Jack Weisenburger

Thanks for having me @mbain_38 @3PD_Performance ! Great experience all around. Free agent still seeking an opportunity to get out and compete this spring.

Jack Weisenburger | Pro Day 2026 Ran fastball up to 96.4, averaged 95.7, mid 80s slider and a changeup. Got valuable experience in the Atlantic league last summer. Big time arm🔥 #OwnYourFuture

@CraigStem You’re the man Craig!

SIGN WEISENBURGER Jack is about to have a major career resurgence! The PR at 98 mph is huge! Keep in mind he’s doing this indoors in January in Michigan. Average velocity will easily be 95+ He got valuable experience as a starter in the Atlantic league last year Totally different pitcher than when he was last in the minor leagues. Sign the man. DM me for more info on Jack! @TreadHQ
