Phillies Prospect Moisés Chace Undergoes Tommy John Surgery

Moisés Chace, a top pitching prospect for the Philadelphia Phillies, will undergo Tommy John surgery after experiencing a significant drop in velocity and elbow discomfort during the 2025 season. Acquired last summer in a trade with the Baltimore Orioles, Chace had shown promise with strong velocity and strikeout numbers but struggled with control and conditioning this year. Phillies manager Rob Thomson confirmed the surgery, noting that Chace was removed from a recent start due to elbow issues and is likely to miss the remainder of the season, with a possible return not expected until mid-2026. The 21-year-old right-hander had a 3.24 ERA and 1.62 WHIP in six starts at Double-A Reading, but his fastball velocity fell from around 95-97 MPH last season to about 90 MPH this year. The Phillies had concerns about his physical conditioning coming into spring training, and his decline led to further medical evaluation and the surgery decision. Chace's injury is a significant setback for the Phillies’ pitching prospects, especially following his promising acquisition alongside Seth Johnson in the Soto trade.
