Jake
Mazzier

‘26 RHP Jake Mazzier (Gibson Southern) was the biggest winner on the mound. The uncommitted right-hander features an athletic 6-foot-1, 175-pound frame with room to add strength. His athleticism and arm speed immediately stood out, and he showed the best stuff of the day. Mazzier sat 87–89.8 mph with the fastball, which played with life through the zone. His best pitch was a quality 75–76 mph slider with sweep, profiling as a future swing-and-miss pitch. He also mixed in a low-80s changeup with fading action and flashed a mid-80s sinker, as well. The delivery is clean and athletic — he works to a moderate balance point before an aggressive move down the mound. The arm is uninterrupted and quick to a ¾ slot. Shortly after the event, Mazzier earned an invitation to the Prep Baseball Future Games, where he'll represent Team Midwest.

I was excited to see the development from '26 RHP Jake Mazzier (Gibson Southern). Mazzier has made really solid strides since my last looks on him, maturing into an athletic, 6-foot, 175 pound frame. Mazzier moves with a quality mix of athleticism and control, reaching a moderate balance point under control before a more intentful move down the slope. The arm works clean on the backside with above average arm speed. As a youngster, I was fond of his ability to spin the baseball. As he has matured, he has been able to maintain that quality while elevating his overall athleticism and stuff. Mazzier spun a low-to-mid 70s curveball that reached 2700 spin with two-plane shape to allow for wipeout upside. The breaking ball is only complimented by his fastball, which has improved vastly in the past 12 months, now sitting 85-88, touching 89 mph with 20" of IVB on average. A true carry fastball, combined with future-wipeout spin, is a combination that will allow him to really miss bats. Mazzier showed an upper 70s change as a usable third pitch.
