Another Hitting Disciple making noise. 🔥
Nathan Wong (‘27, IL) drove a ball in the gap for an RBI single. Uber quick hands that put barrel on ball. #WCOpen

Another good BP session with @CoachRalf - Exit velo averaged over 90+mph, hitting my highest at 98mph.

Completely agree.
Mookie stops the hitter: “Why swing harder?” Young hitters think more effort = more damage. But your best performance usually isn’t max effort. It’s the effort level where your technique stays clean, you square balls consistently, and the barrel keeps good direction.
