+ RHP Jacob Mrosko (Chanhassen HS, MN), a Purdue recruit, was effectively wild for the Mariners Scout Team on Friday night. He dodged barrels all game long against GRB Rays Green but couldn’t help but dishing out five free passes. Still, Mrosko had his swing-and-miss stuff. The 6-foot-2, 185-pound prospect sat 87-89 mph in the first frame, touching one 90 mph, and grappled with his 12/6 breaking ball. After that first inning of work, in which he pitched over walking the bases loaded, Mrosko mostly settled in as he sharpened his curveball. His lively fastball still burst out of his hand, earning empty hacks up in the zone especially, but Rays bats were also too tempted by his breaking ball that bit beneath the strike zone. Mrosko showed precisely why he’s both committed to a program like Purdue and ranked No. 5 overall in Minnesota’s 2020 class.

6-foot-2, 175-pound left-handed hitting 2-way player. 2018 Futures Games participant and Purdue commit.  Ranked #453 Overall in 2020 class.  7.01 runner.  Athletic frame.  Slightly open balanced start.  Small leg lift and hands load back.  Big swing.  Uses the whole field with line drive and fly ball contact.  Flashed average pop with good barrel contact.  85 mph exit velocity.  OF- Athletically moves to baseball.  Fields ball clean.  Good footwork into throws.  90 mph arm strength with above average carry and average accuracy.  On mound- Athletic mound presence.  Good tempo.  Lands across body down mound.  Arm works and throws from a high ¾ arm slot.  Fastball was 89-90 mph with late cut action.  Curveball has 12/6 break with solid spin and shape at 68-70 mph.  Change-up has average feel and can be firm at 79-81 mph. 

2018 PBR Future Games- Mrosko has some funk in his delivery that creates deception. The FB sat 86-88 and crept up to 89 at one point and was complimented by the CH at 77-77 with hard arm side drop as his best secondary pitch. His third pitch was a BB 68-71 with 10-4 shape that has the potential to become a + pitch. 0-2 in game action with 4 walks and a HBP.

7/11/18- 6-foot-2, 175-pound left-handed hitting two-way player.  6.91 runner.  Tall stance with rhythm to load and arm bar to start.  Loose athletic swing in the box.  Mid/pull approach with line drive pop in the bat.  85 mph exit velocity.  OF- Athletic in the field with average hands.  Above average arm with online throws and good carry to target.  88 mph arm strength.  On mound- Step to rock left lift in delivery.  Fastball is 83-87 with good downhill action.  Inconsistent feel for above average slider thrown at 73-76 mph.  Firm flat change-up with flashes of fade and sink.

3/17/18- Mrosko touched 87 mph in his bullpen after going through the full workout as an outfielder, and I think there is much more velocity on the way in the future. Tall stance with deeper load, varying swing plane, aggressive swinger, hard pull contact, tends to flare oppo. Athletic in field, long strides, covers ground, well above avg. arm with carry and accuracy to target. Still trying to sync up with the long limbs that his 6-foot-1, 175-pound frame holds, he could have a chance to make a big jump as he becomes more comfortable with the new movement patterns. He ran a 7.01 60-yard dash, and has wiry-athleticism throughout his frame. On the mound, he stepped slightly across his body as his loose arm worked freely in the back before delivering out of a high ¾ slot. Though his curveball was thrown slower at 66-68, it did take multi-tier shape, and has a chance to develop even more in the future. He tended to cut his changeup. Given the fact that he is still figuring out how his long limbs move, and the fact that he should be able to add a significant amount of strength, Mrosko is a player to follow moving forward.
