Jack Postma, the 82nd overall ranked player in the Class of 2028, has announced his commitment to Texas.
‘28 RHP Jack Postma (IL) checks in as the next big time power arm coming out of the Midwest. It’s loud stuff that sees his FB in the low 90s paired with a sweeper & changeup. Athletic operation with a lower 3/4 release. Good extension and continues to be a buzzy name after a great summer. #HookEm commit.

The pitcher with the most interesting ingredients at #PBAAG26? That'd be RHP Jack Postma (Barrington HS, IL, 2028). This is a 6-foot-5, 200-pound righty with a unique release that complements everything he throws.
📐 7.2 ext. / 4.8 rel. height
🔥 FB 91.2 mph (16.2 HM / 13.8 IVB)
🧹 SL 75.8 mph (-18.7 HM / 3.2 IVB)
🪂 CH 83.1 mph (19.0 HM / 5.5 IVB)
A @PrepBaseballIL Future Gamer this year with an immense ceiling. The FB is on an island of its own, metrically, and there's real secondaries.
