2/18/23

RHP Jack Welak (Catholic Memorial, 2025) is a top-40-ranked member of the state’s sophomore class. He stood out again last weekend, where the 5-foot-10, 160-pound athlete displayed a repeatable delivery and a loose arm showcasing the ability to drive balls through the zone with his tailing fastball at 82-83 mph. He also wields a slider with big lateral movement that he can land in the zone for strikes and expand for chase and swings and misses. Finally, Welak showed impressive feel for a fading changeup at quality arm speed to round out his three-pitch mix. He’s an interesting uncommitted follow to monitor this spring and summer.

Welak made a strong impression on our scouting staff on Sunday, boasting a heavy sinking fastball up to 80 mph. Welak then went to a sharp 10/4 slider at 69-72 mph while showcasing mature feel, navigating it around the zone with ease.
