Giants’ José Buttó Undergoes Arm Surgery, Set For 5–6 Month Absence

Giants reliever José Buttó underwent surgery to repair an axillary artery in his upper right arm and will miss 5–6 months. In 2025, he went 5-3 with a 3.90 ERA and 58 strikeouts over 67 innings. The setback leaves San Francisco with a bullpen gap as Buttó begins a long recovery process and starts rehab while rotation depth thins quickly.
