RHP Justin Mitrovich (Elon Baseball) is one mid-major arm... to follow this season. Was excellent as a true Freshman and pitched his way to a 3.68 ERA with 66 Ks to 21 BB across 63.2 IP. Last spring he worked a 5.06 ERA and collected 96 Ks against 30 BB in 80 IP. Mitrovich also showed positive flashes on the Cape this summer and notched 17 Ks in as many IP. Mitrovich has an athletic frame at 6'3" and 200-lbs. Room to fill out physically. Worked exclusively out of the stretch during the spring, but went back to the windup this summer. Works on the 1B side of the rubber, starts his motion with a small side step then gathers himself. Leads into a high lift, and the rest of his operation is up-tempo. Plenty of depth on his long arm stroke, attacks from a three-quarters slot with present arm speed. Some effort. Mitrovich's FB sits in the 91-94 range, but has been up to 96 with some life in the top-1/2 of the zone. Figuring his heater out is going to be the key for him going forward. Threw mostly 4-seamers during the spring, but went 2-seam heavy during the summer and still generated a whiff rate < 20%. A handful of the latter flashed late arm side life, particularly against LHH. Both play well in the top-1/2 of the zone. Needs to iron out the shape and maximize it. Mitrovich's bread-and-butter offerings are his secondaries. His low-80s CH is one of the best of its kind in the college ranks. Averaged over 12 MPH off his FB last spring and is a legit swing-and-miss pitch against both LHH and RHH. Throws it with conviction and will use it in any count. Consistently flashes fade to the arm side as well as ample late tumbling life. True "falling off the table" look. Mitrovich's feel for the pitch is highly advanced, and last spring it generated a 52% whiff rate, 47% chase rate and held opposing hitters to a .198 average. Comfortably a 60. Rounds out his arsenal with a low-to-mid-80s SL that is a particular weapon against righthanded hitters. Gyro look that's not big in shape, but will flash some lateral glove-side life with late bite. Flashed above-average at times last spring and garnered a 45% miss rate. Gets whiffs both in and out of the zone. Mitrovich is a strike-thrower who looks the part of a starter at the next level. As mentioned, the key with him is developing the FB. Fits as a 5th-7th rounder for me right now. (📽️: Elon Baseball)show more

RHP/1B Trace Phillips (Middle Tennessee Baseball) is an interesting... draft-eligible sophomore on which to keep close tabs. Last spring, he hit .304/.360/.547 with 8 2B, 13 HR and 47 RBIs, but it’s his ability on the mound that's the root of his buzz. Phillips' back of the baseball card numbers last season are modest, but there is more to it than meets the eye. At 6'3" and 185-lbs, Phillips has an athletic, high-waisted frame. In the box, he has a simple setup with an ear-high handset and the bat horizontal above his back shoulder. Phillips has a slight load in which he has a noticeable barrel tip and a small stride. He moves well in the box and has some scissor action with his back leg. Phillips’ pure hit tool is fringey, but he has plus raw power and has shown the ability to drive the baseball to all fields. Max EV last spring of 109.4, if he's able to lift the ball more it will lead to a more impressive power output. Phillips’ current prospect status is largely driven by his ability on the mound. His numbers were unimpressive last season, but he took a step forward this fall. There’s some low hanging fruit to clean up in his delivery, but he has a short, whippy arm stroke and attacks from a low-three quarters slot with plenty of arm speed. Phillips’ FB has been up to 96 with ride through the zone (particular life at the top), though his best pitch is a high-70s-to-low-80s CH. He does a nice job of killing spin on it, and It averaged almost 15 MPH off his fastball this fall. It’s a plus pitch that flashes both fade to the arm side as well late tumble. Phillips completes his arsenal with a mid-80s slider that flashed above-average this fall with sharp, two-plane tilt. Both his changeup and slider profile as legitimate swing-and-miss offerings. Another positive development with Phillips this fall is that his strike-throwing took a step in the right direction. Mid-4th-6th round type this July. (📽️: Middle Tennessee Baseball)show more

2027 RHP/1B Cole Kuhn (St. Joseph's Prep, PA); 6-4,... 185 lbs. 🚨 Sidearm ‘27 up to 91 🚨 FF: 87-90 (outlier VAA, life) SI: 89-91 CB: 72-74 CH: 77 Arsenal can go a lot of ways. Could evolve to SI/SW, but wouldn’t rule out the high-carry FF (18+ IVB). Tough look for any hitter from a long-lever frame that doesn’t throw anything straight. If you’re a fan of pitch design, outlier arsenals, and potential draft picks - this is your guy. Even more in the tank and command should improve as the young man gets more innings under his belt. #PreseasonID | @ColeKuhn2 | Shooter Huntshow more

LHP Andrew Healy (Duke Baseball) is one of my... favorite Sophomore-eligible arms in this year's Draft. Enjoyed an outstanding true Freshman campaign in '23, pitching his way to a 2.32 ERA with 45 K to just 7 BB across 42.2 IP. Great body at 6'6" and 200-lbs. High-waisted with room to fill out. Smooth, aesthetically pleasing operation on the mound. Clean arm stroke and hides the ball well. Attacks from mid-three quarter slot. Pretty low effort delivery. Healy's FB will mostly sit in the 90-93 range, but he has been up to 94/95. It gets on hitters quick and plays particularly well on his arm side/elevated. Little bit of carry to it. Healy has plus command and control of it. His go-to secondary offering is a high-70s CH that on average is 10+ MPH off his FB. Healy maintains his arm speed well and it features serious late tumbling life. Had a 40% miss rate in '23. Would put a 55 on it. Healy features two distinct breaking balls in a high-70s SL and mid-70s CB. SL has long, sweeping action and is particularly deadly against LHH. After throwing it just 5% of the time in '23, Healy this fall has upped his CB usage. It's an okay 4th pitch and at times will flash some depth. Perhaps most interesting about Healy's profile is his ability to generate swings. Last year he posted a 48% overall swing rate and an impressive 70% in-zone swing rate. Overall control/command would grade out as a 60. Healy is a slam dunk starter professionally and could pitch his way into a top-3/4 round Draft choice. (📽️: Duke Baseball)show more

Shortstop Kyle DeBarge (Louisiana Ragin’ Cajuns® Baseball) is one... of my favorite non-P5 Draft prospects. After a strong Freshman season, DeBarge enjoyed a sensational Sophomore campaign in which he hit .371/.448/.546 with 15 2B, 7 HR, and 18 SB. Was an All-Sun Belt selection last year. Plays bigger than his 5'9", 175-pound frame suggests. Twitchy, athletic operation in the box. Front side starts slightly open, minimal load and stride with not a lot of unnecessary movement. Above average bat speed, extends really well through the baseball. Does a nice job of creating leverage to the pull side. Plus-plus bat-to-ball skills with an 88% overall contact rate (93% against FB), and an absurd 95% IZ contact rate. Advanced feel for the barrel. Pure hit tool is a 60. Strong defender up the middle with smooth actions. His natural athleticism really shines. Quick feet, good internal clock. Arm is a borderline 55, could end up at 2B long term where he profiles as an above average defender. 70-grade runner who this summer turned in < 4.00 home-to-first times. Absolutely flies when in gear! Product of National power Barbe High School. DeBarge is a winner and a leader in the dugout. Potential top-two round pick this July.show more

RHP Cole Leaman (Lehigh Baseball) is an arm I'm... really looking forward to following this spring. Fresh off a strong Sophomore season in which he worked a 2.31 ERA with 49 Ks to 23 BB across 46.2 IP. Showed some positive flashes on the Cape. While slightly undersized, Leaman has a strong and athletic build at 6' and 190-lbs. Has put on a lot of good weight over the last couple of years. Leaman has almost a "check point" delivery in which he takes a noticeable side step towards the 1B side, gathers himself and breaks into the rest of his motion. Lengthy arm stroke and attacks from a high-3/4 slot from a low release height. Leaman is a high-level athlete and a dynamic mover on the mound. Sits really well on his back glute and his lead leg block enables him to generate power and drive his back side through. Drop and drive delivery. Little bit of effort, but plenty of arm speed. Leaman's FB sits in the 91-94 range, but it was up to 96 this summer and 98 this fall. Jumps out of his hand from a ~5'3" release height and flashes riding life through the zone. Averaged 15" of carry this summer and 2,361 RPMs. Gets over the barrels of opposing hitters when located in the top-1/2 of the zone, which is where the pitch is at its best. Command can be erratic at times. Would give it a 55. Leaman's most-used off speed pitch is a high-70s-to-low-80s CB. Shape is inconsistent and it can get a little slurvy at times, but he snapped off a handful of really good ones between the spring and summer. When it's at its best, it will flash a bigger shape with sharp, downward tilt. Leaman will also mix in a low-to-mid-80s SL that's distinct in shape. Another pitch he's still gaining a feel for, but like his CB it's also shown big time flashes. Shape of it will vary, but it will sometimes flash plus with sharp, two-plane break (more sweep than depth) and essentially take a late, hard left turn. Rounds out his arsenal with a high-80s cutter and a mid-to-high-80s CH. The former is more intriguing than the latter. Curious to see how much he uses the cutter this spring, threw a couple this summer that had late glove-side life. Leaman has a very intriguing blend of athleticism and stuff, though he'll need to iron out his command and control in order to maximize his upside. As mentioned, it's a bit scattered right now and has hindered him in some starts. 5th-8th round type this July. (📽️: Falmouth Commodores)show more

Today's #SaturdaySleeper is RHP Derek Vartanian (Campbell Baseball). He... comes to Campbell by way of Gaston College, where last season he pitched his way to a 3.08 ERA with an impressive strikeout-to-walk ratio of 76-to-9 across 76 IP. Slender build at 6'4", 200-lbs. Short, quick arm stroke and attacks from a high-three quarter slot. Vartanian's FB will sit in the 93-96 range, but this fall he topped out at 98. Features big time carry through the zone with upwards of 24" of IVB. There is still likely more in the tank, especially with better use of his lower-half. Vartanian features two distinct breaking balls with a SL and CB. High-80s gyro SL is still developing, but at times flashes effective late, lateral movement. Low-80s CB boasts big time depth with some teeth and almost true 12-6 break. His best secondary pitch is his Splitter. It plays really well off his FB as it sits 80-82, and features big time fade to the arm side with some tumble. Vartanian does an excellent job of killing spin, and the spin rate on his changeup will get as low as 800 rpm. Vartanian this spring will anchor Campbell's rotation and be the cornerstone of the Camels pitching staff. An advanced strike thrower whose stuff will only tick up, Vartanian profiles as a starter professionally and a potential Top 5 round pick this July.show more

Was very impressed on Friday by East Carolina RHP... Trey Yesavage, who allowed just 1 ER and struck out 11 across 6 IP. FB sat 93-96, topped out at 97. Jumped out of the hand from his near over-the-top slot. Plenty of carry through the zone, shape of the pitch is outstanding. Control and command of it were both impressive, threw it for strikes 73% of the time. 55, borderline 60 pitch. Mixed in two distinct breaking balls with a high-70s CB and mid-80s SL. It's clear on Friday he didn't have the best feel for his CB. Threw a couple good ones that flashed plenty of depth, but it lacked its usual sharp, downward bite. Will typically flash plus. Gyro SL was a lot better. Threw it with conviction, confidence in the pitch was there. Flashed late teeth with some depth, generated 7 whiffs. Would give it a 55. I was most impressed with his SPL-CH. Got nice separation off his heater with a 10+ MPH difference. Threw it to both LHH and RHH. Flashed ultra-late tumbling life; seemingly fell off a table ~1-2 feet in front of the plate. Kills spin really well. Maintained arm speed. Looked like a plus pitch. Yesavage this year has a 1.80 ERA with 19 Ks to just 3 BB across 10 IP. He is one of the premier college arms in this year's draft class and has first round upside. (📽️: ACC Network)show more

While he won't toe the rubber this spring for... the Hoosiers, RHP Luke Sinnard (Indiana Baseball) is an arm to be familiar with come July. Began his college career at Western Kentucky, but blossomed last year as a Sophomore at Indiana and pitched his way to a 4.27 ERA with 114 Ks (led the Big Ten) to just 25 BB across 86.1 IP. Earned a Second Team All-Big Ten selection. Towering, workhorse frame at 6'8" and 230-lbs. Sinnard attacks from an ultra high-three quarter slot and possesses an outlier release height north of 7-feet. Somewhat of a deep pull here, but his arm slot is a little reminiscent of former College of Charleston RHP William Privette, though not as sling-shotty or true OTT. His FB sits in the 91-94 range (T96) but it plays up thanks to the carry Sinnard is able to get on it through the zone. Last year, it averaged over 2,500 RPMs and over 19" of IVB. Sinnard's low-80s CB is a true bat-misser. Flashes immense depth and almost true 12-to-6 shape with some teeth. He has good feel for the pitch and it is effective against both right and lefthanded hitters. Held opponents to a .118 average and generated a 46% miss rate last spring. Also features an effective high-80s Cut/SL hybrid. Boasts late lateral life with a touch of depth. Gets under the hands of LHH. Another pitch that Sinnard has plus control of. Lastly, Sinnard throws a low-80s Split/CH. Feel for it is inconsistent, but it gets good separation off the FB and at times flashed tumbling life. It's an okay 4th offering. Sinnard has pro-level starter written all over him and even though you won't see him this season, he profiles as a potential 4th-7th round pick in this year's Draft. (📽️: Indiana Baseball)show more

LHP Zach Root (Arkansas Baseball) is one of the... best college lefthanders in this year's Draft class. After splitting time between the bullpen and rotation as a Freshman, Root last year was a full time starter and pitched his way to a 3.56 ERA with 76 Ks to 21 BB across 68.1 IP. Slightly undersized at 6'1" and 186-pounds, but there's present strength and physicality in his lower-half. Natural funk and deception in his delivery that includes a high leg lift and some tilt in his upper-half. Average arm stroke with a slight wrist coil, attacks from a mid-three quarter (maybe a tick lower) slot with a bit of cross fire. Root's FB will sit in the 91-94 range, but it was up to 97. Will flash arm side life through the zone and is best when located on either third (arm or glove side) of the plate or in the top-half. Not a real bat-misser right now, so refining its shape should be a point of focus both this spring and beyond. Bread and butter offerings are his secondaries. Root's low-80s CH gets averaged almost 10 MPH of separation off his heater and it's a pitch he throws with conviction. Consistently flashes fade to the arm side as well as late diving life. Generated a 46% miss rate last spring, would stick a plus grade on it. High-70s-to-low-80s CB flashes big-time depth with some sharpness. 11-to-5 shape against RHH, but will be longer than it is deep against LHH. Has a decent feel for the pitch, and last season it held opposing hitters to a minuscule .048 average while generating a 48% miss rate. Rounds out his arsenal with a mid-to-upper-80s CUT/SL that against LHH will flash sweeping life with some late bite. Potentially average offering. Would like to see his strike-throwing improve this season. Day 1 profile this July. (📽️: ECU Baseball)show more

Shifting focus to 2025, RHP Tyler Bremner (UC Santa... Barbara Baseball) is one of my favorite College arms in the class. As a freshman, Bremner split time between the bullpen and the rotation and pitched his way to a modest 5.37 ERA with an impressive strikeout-to-walk ratio of 80-to-17 across 55.1 innings. Bremner has a lean, athletic build at 6'2" and 180-lbs. He has room to fill out physically and as he does, his already-electric stuff will only tick up. Bremner has a low maintenance, under control operation with present arm speed. He attacks hitters from a high-three quarter slot and his fastball sits in the 93-96 range and tops out at 98. It has elite riding life (averaged over 21" of IVB in '23) and is most effective when located in the top-half of the zone. Between its velocity and shape, it is a 60-grade offering. He boasts two quality secondary offerings in a mid-80s changeup and low-80s slider. Bremner’s changeup is the more polished of the two, but his sweeping slider has plus potential. In 2023, Bremner’s changeup generated an impressive 48% miss rate. He has advanced feel for the offering, and he will throw it to both left and righthanded hitters. It plays well off his mid-90s fastball and flashes big time late tumbling life and some fade to the arm side. Bremner threw his slider just 12% of the time in 2023, but it has the chance to be a true out pitch in the future. It features ample late sweeping life as well as some depth, and is a real weapon especially against righthanded hitters. It has reportedly taken a step forward this fall and could be a lethal offering in 2024. Between his plus control, low effort delivery, and the chance to have three plus or better pitches, Bremner profiles as a starter professionally. He has a chance to become a household name this spring and with two strong seasons pitching in the rotation, Bremner has 1st Round upside in 2025. (📽️: UC Santa Barbara Baseball)show more

Everybody says they want it… But Few have the... fortitude to do the things it takes to get what they say they want Seneca 2024 & UPJ commit Zyler Freedman - after a long chase- slays the 🐉 dragon 90 mph off the mound tonight Here’s the story 📖 Zyler came to PVS baselining on the mound at 76.2 summer between Frosh and Sophomore year. No great size or mobility gifts… but what he did have- was the heart of a Lion. And that determination and discipline led to some great gains in his first year at PVS. He had a goal of 90 mph on the mound at PBR in Feb of 2023. He came up short in a memorable display of determination : 88 mph @PBRPennsylvania He dusted himself off and put his efforts into pitch design and command. He became one of the WPIAL’s best pitchers in the toughest baseball section. After that- he went to the Youngstown Class B summer league and pitched well there and committed to UPJ. After his commitment - we sat down and devised a plan. A plan most kids don’t have the patience to execute. It was rooted in Alan Jaeger Jaeger Sports principles of Weening off volume and building two weeks for every down week. We are talking 5 months folks. Throw by throw execution for five months. Five months. Along the way- we built him up using several Randy Sullivan MPT, CSCS concepts as well as tried and tested in house methods. Today was his first “Go day”. And he hit that 90. His boys were as pumped for him as they would have been for themselves. Our plan has just begun - More lay ahead. And what’s certain is- he’ll execute whatever it takes to keep moving forward in this game “It Takes What it Takes” has long been one of our mottos- That’s perhaps never been better demonstrated than Zyler these past 10 monthsshow more

RHP Jacob Mayers (LSU Baseball) is an interesting arm... in this year's Draft class. Was outstanding as a true Freshman and pitched his way to a 2.02 ERA with 105 Ks to 58 BB across 75.2 innings en route to taking home Southland Conference Pitcher of the Year honors and being named a First Team Freshman All-American. Took a bit of a step back in 2024 and compiled a 4.58 ERA with an SLC-leading 106 Ks to go along with 76 BB in 70.2 IP. Mayers has a projectable, high-waisted frame at 6'5" and 205-pounds. He doesn't have the cleanest or simplest delivery and he'll struggle to repeat it at times. Mayers has a somewhat abbreviated arm stroke and attacks from an over-the-top slot with present arm speed. Front side will sometimes fly open which has led to command issues, but there's some pretty low hanging fruit to clean up in his operation going forward (Ex: getting more into his lower-half, refining it to become more repeatable). Adding strength and explosiveness will be key. Mayers' fastball is his bread-and-butter pitch. It sits in the 92-95 range, but has been up to 97 out of an outlandish 7-foot release height. His release height is certainly a contributing factor here, but the pitch also averaged an eye-popping 24.3" of ride and nearly 2,400 rpm. Mayers threw his heater a whopping 91% of the time and was still able to generate a 35% whiff rate, including a 30% (!) IZ whiff rate, on it. There are plenty of outlier traits, but his command is below-average. If he can up his competitive pitch % and stay in and around the zone on a more consistent basis, it will make it that much more effective. While his FB is the money-maker of his arsenal, Mayers will occasionally mix in a gyro SL in the low-80s that lacks teeth right now. He's still gaining a feel for the pitch and there is work to be done on it going forward, but it could be a potentially above-average offering in the future. 40/45 currently. One of the biggest question marks with Mayers is the development of a third pitch. He mixed in a handful of mid-to-upper-80s and a couple piqued my interest; one showed some fade to the arm side and another flashed late tumbling life. It's clear he isn't comfortable throwing it yet, but this could be the pitch to develop at least to the point where it's serviceable. Mayers right now is very much a work in progress and all signs right now point to him ending up in a relief role long term. However, he's a very fun, moldable ball of clay to try and develop and get the most out of. As the low hanging fruit continues to get cleaned up—whether it be at LSU or in pro ball—polish will hopefully follow. 5th-8th round pick right now. (📽️: Nicholls Baseball)show more

OF Nick Dumesnil (California Baptist Baseball) is one of... the higher upside college bats in this year's Draft. Showed flashes across a limited sample as a Freshman, but exploded last year to the tune of a .362/.440/.702 slash line with 40 XBH (19 HRs) and 45 RBIs across 61 games. Proceeded to have an excellent summer on the Cape in which he hit .311/.378/.489 with a league-leading 12 2B, 4 HR, 15 RBIs and a league-leading 26 SB in 36 games. Strong, athletic frame at 6'2" and 205-pounds. Big league body. Slightly wide base in the box with a somewhat high handset (lowered his hands as the summer went on, was ultra-high at school with his bat pointed almost straight down behind his back shoulder. Drew Burress-ish look). Ultra-small stride that is more of a toe tap than anything else. Hands already start pretty far back, though they drift slightly in his load. Engaged lower-half, especially his back side. Easy plus bat speed. Dumesnil showed the ability to drive the baseball to all fields both at school and on the Cape. Would give his power a 55 overall, but it's a 6 to the pull side. Top spun a 2-run HR (EV of 106) off the scoreboard in the ASG. Very curious to monitor how his hit tool progresses this spring. There's a present feel for the barrel and his bat-to-ball skills are plus (ovr. IZ contact rate of 90%, including 93% and 91% against FB and SL, respectively). Will certainly need to shore up his pitch recognition skills and swing decisions in order to maximize his offensive upside. Some chase up/out against FB, down/out against secondaries. Key will be doing a better job of picking up spin out of the hand. Plus runner—who most importantly knows HOW to run—whose speed translates on both sides of the baseball. Chaos-causer on the bases, Dumesnil's speed also gives him the opportunity to take an extra base on a ball in the gap or down the line. I thought his instincts in CF got better as the summer went on. Dumesnil's speed and elite athleticism allow him to cover plenty of ground and his arm is average, I'm sure he'll get the opportunity to prove he can stick there in pro ball. Chance he could move off and end up at a corner eventually. Key for Dumesnil is adding polish to his hit tool. There is 5-tool upside (key word) with him and he can impact the game in a number of ways. Potential first round pick this July. (📽️: California Baptist Baseball)show more

Wondering if you are “quad dominant” in your throw... and if you should change it? Maybe you shouldn’t 🤷♂️ A coach’s post coming from Austin Roark 🚀⠀ -⠀ One question I get from a lot of athletes is whether they should change their lower half because their knee is over their toe during their loading phase down the mound. ⠀ -⠀ The biggest thing that I look for when trying to figure out if it is an issue or not is to see how they are able to get out of that position. Some guys are able to leverage and rotate from that position extremely well, which then I would say that it’s not an issue.⠀ -⠀ On the other hand, there are some guys who will get out of this position by driving extension out of their back leg, killing their ability to rotate their pelvis and get it in an open position into landing.⠀ -⠀ This is when I would suggest trying to make a change. I think a lot of people jump into certain ideologies that you shouldn’t do certain things because it’s “inefficient” or it looks “wrong”. ⠀ -⠀ Take a look at these pitchers shown in the video. All 3 of these high level arms have some degree of knee flexion over their toe. Now, granted, they all have insane levers to help them, but the way they are moving is what makes them efficient in how they throw. ⠀ -⠀ I think if you told Dustin May that he had to hold a vertical shin down the mound, it would be a disaster and mess a lot of things up upstream that would impact him in a negative way.⠀ -⠀ The big takeaway here is that there are no absolutes. One thing that may look inefficient to you could be the thing that makes someone else very efficient.⠀ -⠀ When trying to figure out if you should change something about someone's delivery, make sure to look at the entire unit as a whole and don’t jump into any quick changes.show more

Furniture assembly is the task everyone name-drops and nobody... actually attempts at real scale. Every demo I have seen is a scaled down IKEA leg or a single arm on a toy chair. This paper does it properly, real scale, bimanual, up to 7 subtasks and 1,550 control steps per episode, and it is validated on a real Kinova Gen3, not just in sim. That real-robot number is the one that matters: only a 16 percent drop on the hardest task going from simulation to hardware. That is a small enough gap to take seriously, and it did not happen by accident. They built a VR teleoperation rig specifically for coordinated dual-arm collection, because generic single-arm teleop setups do not capture the coordination real assembly needs, and the model predicts a continuous progress signal alongside the action chunk rather than a discrete subtask label, letting it auto-transition and catch drift before it compounds into total failure. The simulation ablation is what got them there, 48 to 80 percent over baselines, with another 21 points from their perception and control design study alone, but that is groundwork, not the headline. Watch the video, there is a clip of the robot misgrasping the seat panel, reopening the gripper, and regrasping on its own. That is not scripted recovery behaviour, it emerged from training, and it emerged on hardware. Excellent work from the team from Mitsubishi Electric Research Laboratories, with Oxford and UNC Chapel Hill Clinical Laboratory Science.
