Built at an upside 6-foot-1, 174 pounds, LHP/OF Logan Wierzba (West De Pere, 2026) put together an intriguing two-way performance on Saturday. On the mound, the southpaw features an uptempo delivery and is a dynamic mover downhill with a shorter, efficient arm action. He pounded the zone with his low-80s fastball which played with some heavy arm-side run, over a foot on average. He also spun in a 12/6 breaking ball and a changeup with slight cut at times. With the bat, he took short and direct swings to the ball working gap-to-gap and registering a max exit velocity of 93 mph.
Wierzba impressed during his championship game start on the mound. High ceiling left-handed pitcher that showed above average pitchability. Three pitch mix with a fastball that sat in the upper-70s and touch 80 mph a handful of times. Flashed feel for a changeup in the low-70s that got swings and misses low in the zone. Also used a curveball with depth to get hitters out in front and force weak contact.
Uncommitted. Gave an intriguing look on the mound for GRB Rays North. The southpaw worked his fastball up to 80 mph with a loose, fluid arm action. Ripped off a 61-63 mph breaking ball to pair off the fastball.
The freshman had a stellar week for the Phantom's. He threw a complete game with 11 strikeouts, one walk, no earned runs and two hits allowed in their 4-3 win over Menasha.
