Giants Pitcher Undergoes Blood Clot Procedure

San Francisco Giants reliever José Buttó is set to undergo a procedure to address a blood clot discovered in his pitching arm. The announcement came on Friday, April 4, 2026, following his placement on the 15-day injured list the previous day due to right arm tightness. This development occurred after Buttó experienced a significant drop in velocity during his most recent outing against the Padres on Wednesday, April 1, 2026.

Following Buttó's injury assignment, the Giants promoted Blake Tidwell, who successfully recorded his first Major League save on Thursday, April 2, 2026, against the New York Mets. The team had initially hoped Buttó would only miss the minimum 15 days on the injured list, but the discovery of the blood clot has altered that outlook. Further details regarding his prognosis and recovery timeline are currently unavailable.

Buttó was acquired by the Giants last July in a trade that also brought Tidwell and outfielder Drew Gilbert from the Mets. Last season, Buttó made an immediate impact on the bullpen after joining the Giants. He appeared in 55 games, posting a 5-3 record with 58 strikeouts in 67 innings pitched.
