The Mid-Atlantic ProCase was held on Saturday, February 10th at the TSI Training center in Henrico, Virginia. Prospects from Delaware, Maryland, and Virginia came out to showcase their talent in front of scouts from around the region. Though it was a majority of 2018 graduates hoping to turn a few heads, there were also a small amount of 2019 and 2020 graduates wanting to get their names out early. Today we are doing the first of a three part series where we give our initial thoughts from the event.  

Early Thoughts from the Mid-Atlantic ProCase


Jacob Zebron RHP / OF / Colonel Richardson, MD / 2018

One of the most impressive performances from the event came from the arm of this Eastern Shore right handed arm. Zebron has a long and lanky 6-foot-2, 181-pound frame with a free arm action throwing from a high three-quarter slot. Zebron pitches with light effort but the ball came out with a fury that got up to 93 during the day which was an event best. He had a big breaking ball that he threw with confidence and a change-up that he does slow down on but shows potential. Most exciting is that when you watch Zebron you see that he still has untapped potential in his velocity as he add room to that long and lanky frame.


Wesley Clarke C / 1B / Liberty Christian, VA / 2018

Clarke was our highest ranked 2018 in the class there and the South Carolina commit showed quickly why we think so highly of him. He was making loud contact throughout his rounds of BP that got better with each swing, putting frozen ropes on the net out at TSI. Clarke then posted a top pop of 1.94 getting up to 82 mph from the catcher position. Clarke's receiving ability might the part of his game I like the most, and he continued to show that again at the ProCase. Catching a lot of new arms with high velo and late breaking off speed, Clarke made them comfortable and caught each different arm with ease.


Seth Mayberry RHP / 1B / Dinwiddie, VA / 2018

One of the biggest risers from the event had to be this much improved righty from Dinwiddie HS. Mayberry has made noticeable improvements to his 6-foot-2, 195-pound frame looking much more put together. On the mound, Mayberry had one of the more impressive days pitching 90-92 with a 79 mph breaking ball. The breaking ball showed late breaking action, though he did leave a little up in the zone. He pitches with some effort, but with his lightening arm, Mayberry was one of the big winners from the event.


Alex Greene OF / RHP / DeMatha, MD / 2020

Maryland's No. 1 in the 2020 class and No. 10 in the PBR overall 2020 rankings did not disappoint at the ProCase. Green arguably had the best workout of all players in attendance, showing explosive quick twitch at the plate to go along with his howitzer from the outfield, getting up to 95 mph on his outfield throws. On the mound, Green was 88-90 and showing late sink on his two-seam fastball. He showed good command of his arsenal, and showing difference between his two offspeed. His bigger action breaking ball was up to 74 mph while his late action slider topped out at 80 mph.




Lliam Grubbs RHP / SS / Louisa, VA / 2018

Command of the zone and the ability to manipulate the baseball, that's what Grubbs does. The low slot righty topped out at 87 on the day, but his frame and arm speed tell you he will get more velocity as he gets older and adds to his frame. What impressed the most, was his ability to make the ball dance at times, with later life on all his pitches. Grubbs ability to spin the baseball and command/action on his change-up should give him an opportunity to contribute pretty quickly at the next level and as he gets stronger could be an interesting arm to watch down the road.




Hunter Hoopes RHP / OF / W.T. Woodson, VA / 2018

Hoopes has been one of the better stories of 2017, where one year ago the lanky right-hander was sitting 81-84 at our Underclass preview. We knew that eventually the velo was going to match the arm speed, and that was the case early this summer where Hoopes was pitch up to 87, then touching 89 at our top prospect games and then this weekend at the ProCase topped out at 91. I still don't think this kid is done gaining velo. I would personally like to see his offspeed at a higher velocity than it currently is, but Hoopes will be one to follow to see how much more he can gain and especially as he adds to his frame.




Thomas Keehn SS / RHP / DeMatha, MD / 2019

Another candidate for the top workout of the day had to go to this talented underclassman. Keehn has really begun to fill out his frame and is playing the part as well. At the plate it was a little longer path at the plate, but Keehn showed bat speed and some explosion as well, Keehn was a solid defender in the field, looking like he has filled out to fill a third base role. On the mound, it was a clean delivery and arm action that produced 92 with regular effort. Really like his breaking ball that showed true 12/6 action that bottomed out at times.




Sayo Kintunde LHP / Patuxent, MD / 2018

Possibly the biggest breakout performance came from this raw left–handed prospect from southern Maryland. A physical 6-foot-3, 200-pound frame, Kintunde was a little known arm who had been slowly gaining momentum this winter with rumors of his live arm and gaining velocity. Kintunde threw one of the easier 88's on the day and looks to have plenty more in the tank with his low effort delivery and fast, easy arm speed. Kintunde spun a 1/7 breaking ball with good arm speed up to 73. With the strong and longer athletic frame, its hard not to think that Kintunde will continue to gain velocity as he gets older.
