Caleb
Mosley

Athletic 5-foot-11, 179-pound frame. Mosley would showcase a fastball up to 86 mph to pair with a 12/6 curveball at 71-74 mph. Worked strictly from the stretch while showing a deceptive arm action from a 3/4 slot, hides the ball well out of the hand. Not too often you find a left-hander with stuff like this still on the market, so Mosley seemingly earned more attention for himself following his performance in Franklin.

+ This was our staff’s first viewing at LHP Caleb Mosley (Waukesha North, 2026) and we were pleasantly surprised. Mosley measured at 5-foot-11, 177 pounds with more strength coming to his frame. The left hander used a smooth and easy delivery to drive the 86-87 mph fastball through the zone. He used a sharp sweeping type slider out of the same window as the fastball at 73-74 mph and was able to locate the pitch in the zone for strikes. He also showed feel for a 73-75 mph change up to round out his three pitch mix which should play well as a starter. Mosley opened some eyes on Sunday and is a name that is being talked about among the Prep Baseball staff.
