San Francisco Giants right-handed pitcher Jose Butto is scheduled to undergo a procedure to remove a blood clot from his right arm after being placed on the 15-day injured list with arm fatigue. Butto had been experiencing discomfort and struggled in his first two innings of the season, posting a 22.50 ERA.

Why it matters

Blood clots can be a serious medical issue for athletes, potentially sidelining them for an extended period. Butto's injury is a setback for the Giants' pitching staff as they look to bounce back from a disappointing 2025 season.
