Thank you, MLB DC! 🌟 One month and four weekends of northeast @PBRTournaments action has officially wrapped up for the MLB Development Center squad based out of Wuxi, China! All 22-rostered guys got to showcase their talent in some great competition across the empire state including this year’s annual #NYSGames. They ended off their stay here in Cortland as champions of the #NYSummerChampionships 🏆 Thankful to have had this great opportunity to cover these young athletes and watch them grow and improve as the weeks went on while competing in our tournaments at the @LumberYardNY!

2025 RHP/OF Trout He (ChangZhou Beijiao HS); 6-0 175 lbs FB: 87-89 T90 SL: 75-76🥏 Clutch relief appearance by the ultra-physical utility man. The SL has been the pitch of the afternoon thus far. Super late, deceptive break✔️ Peppered the k-zone w/ a firm, arm side FB that missed many barrels. Impressive outing‼️ #NESummerChampionships | @prepbaseballint | #MLBChina | @pbtscouting
