Stone underwent right shoulder surgery Wednesday and is likely to miss the entire 2025 season, Juan Toribio of MLB.com reports.
Stone was initially sidelined with right shoulder inflammation in early September and was unable to return. He'll now likely be sidelined for all of 2025 after posting a promising 3.53 ERA and 1.21 WHIP with a 116:37 K:BB across 140.1 innings in 2024.
