I guess this is D3 Baseball these days, or at least you’re seeing more of it. 92-94 T95 mph out of Ithaca, Jack Picozzi Keep an eye out for this rising arm. He’s only getting better. @FlatgroundApp

RHP Jack Picozzi JR | '26 elig. @Ithaca_Baseball SI: 91-93; 94 x1; 95 x1 CT: 84-85 SL: 80-81 CH: 84-85 Legit D3 arm. Fluid mover with feel for 4 pitches. Was getting 20+ HB on some sinkers + 2600+ spin on the slider. Some rawness but definitely worth another look this spring.
Saw this kid yesterday at a D2/D3 scout day. Definitely something here. Was 91-94 t95 with a 4 pitch mix. Will have some video up later.

Extended look at Cole Kuhn (‘27 PA) really high ceiling with the 6-6/195 frame and unconventional arm angle, great action on his entire repertoire…sinking FB 87-92/93 with low-80s sweeper and occasional CH @PG_Uncommitted #WWBAWorlds

Marlins righthander Karson Milbrandt used his AFL debut to show off his filthy cutter. Batters came up empty 9 of the 15 times they swung at the pitch 👀⤵️

TB to the days where you get cut bc u weren’t good enough for “travel ball” and u weren’t placed on a “C” team to just go pitch 2x/wkend + play the field just to lose #Development

Athletes that specialize early in baseball/pitching need to make up for lack of exposure to movement solutions But how? 1. Variety in the weight room 2. Athletic throwing Why? This dials in feel for their body, time & space. All critical to continue raising their ceiling

Arkansas transfer Michael Anderson should be in the lineup every day for @PennStateBASE, but his upside on the mound makes him even more intriguing. @Michael_A110's fastball averaged 88 mph as a Rhode Island freshman, but it averaged 97 in our 17-pitch look this fall.

Great bullpen @AscentAthlete on Friday. FB sitting 87-90 (video #1) and offspeed stuff feels solid (video #2). Looking forward to the @i95Metro showcase on 10/12. Thank you for getting me right this phase @samgrace_31 @kellerbsbl @PitchincoachPRO. The hard work is paying off and

#Uncommitted Daniel Kellis (‘26, PA) works from a big + strong RH frame w/ length. Goes from the stretch, working into a high + quick LL and a long AA + 3/4 slot. Got a run/ride FB up to 93 (90-92) w/ added ASR at times. Mixed in a tight hz SL w/ late bite. #JrSubwaySeries
