San Francisco Giants reliever José Buttó has been diagnosed with a blood clot in his pitching arm, requiring a procedure to remove it. The discovery comes after Buttó's recent struggles on the mound, with a 4.50 ERA in 2025 and a rocky start to 2026. The team has been tight-lipped about the specifics, but the absence of a return timeline suggests a cautious approach as Buttó embarks on his recovery.

Why it matters

Blood clots can be associated with thoracic outlet syndrome, a condition that has affected other pitchers, raising questions about Buttó's long-term health and the potential impact on his career. The situation also highlights the physical toll that baseball can take on the human body, and the fine line between perseverance and health risks that athletes often face.

The details

Buttó was acquired by the Giants from the Mets in a trade last summer, and was expected to bolster the team's bullpen. However, his recent performances have been less than stellar, leading to the initial diagnosis of arm fatigue. The discovery of the blood clot adds a new layer of complexity to his situation.

  • Buttó has been pitching with this issue for a while, according to reports.
  • The procedure to remove the clot is a necessary step in Buttó's recovery.
