Phillies Prospect Moisés Chace to Undergo Tommy John Surgery, Sidelining Rising Star…

The Philadelphia Phillies have announced that top pitching prospect Moisés Chace will undergo Tommy John surgery, marking a significant setback for both the young right-hander and the organization’s pitching depth. The news broke ahead of Friday’s matchup against the Pittsburgh Pirates, as reported by The Philadelphia Inquirer’s Lochlahn March.

Chace, a 21-year-old native of Venezuela, had been one of the Phillies’ most promising arms heading into the 2024 season. Acquired from the Baltimore Orioles as part of a three-player deal at last summer’s trade deadline, Chace quickly drew attention with a strong showing in his initial appearances for Double-A Reading. His performance earned him a spot on the Phillies’ 40-man roster and a No. 5 ranking among the club’s prospects by MLB Pipeline.

However, the 2025 season brought challenges. Over six starts with Reading, Chace experienced a noticeable decline in velocity and struggled with control, finishing with a 3.24 ERA and a 1.62 WHIP across 16 2/3 innings. These signs ultimately led to further evaluation and the diagnosis requiring surgical intervention.

Tommy John surgery typically requires a recovery period of 12 to 18 months, meaning Chace will likely be sidelined for the remainder of the 2025 season and potentially a portion of 2026. Despite the setback, the Phillies remain optimistic about his long-term potential, citing his youth, work ethic, and prior success as key reasons to believe he can bounce back.

While the injury is undoubtedly a blow, especially for a team looking to bolster its future rotation, it’s also a reminder of the challenges young pitchers face on the path to the majors. The Phillies will continue to monitor Chace’s recovery closely, with hopes that this pause in his career is just a brief detour on a promising road ahead.
