Calvin Koo (‘23, Ga.) showing some feel for a 2 pitch mix. FB 83-85 early living down in zone. Also flashed a fading CH in mix-70’s. Goes CH-FB here for a weak ground ball to end the inning. #SELaborDay @PG_Uncommitted pic.twitter.com/66okbdXIEO

Class of 2029 Tourney All-American Team
We'll open up by saying this; putting together these two teams wasn't an easy task and we could've easily filled another 2 teams without breaking a sweat. There's a mix of Festivalers from last year's 13u game, top 100 ranked players and others who put together spectacular 2024 campaigns and are more than deserving of this recognition.
