MLB Injury Updates & Roster Moves

Major League Baseball saw several key personnel shifts ahead of Sunday's slate, dominated by pitching injury setbacks. The Philadelphia Phillies placed closer Jhoan Duran on the 15-day injured list due to a strained left oblique, according to manager Rob Thomson, complicating late-inning leverage situations. Adding to the National League concerns, San Francisco Giants veteran reliever Jose Butto underwent arm surgery Friday, performed by Dr. Jason Lee at Stanford Medical Center, which is projected to sideline him for five to six months. Conversely, the Arizona Diamondbacks activated outfielder Lourdes Gurriel Jr. from the injured list Saturday, less than eight months after he sustained a torn right ACL in 2025, signaling a faster recovery timeline for the key offensive piece.

Schedule Adjustments & Seasonal Debuts

Roster activities also included a significant activation for the Miami Marlins, who plan to debut outfielder Kyle Stowers on Sunday, allowing the All-Star to finally take the field after battling a hamstring strain. Meanwhile, weather concerns forced an organizational change in the Northeast, as the Boston Red Sox pushed back Sunday's contest against the Tigers by three hours to a 4:35 p.m. start time due to anticipated rain following their 4-1 loss to Detroit on Saturday afternoon. Separately, managerial discipline occurred in the American League when Kansas City Royals manager Matt Quatraro received an early ejection during Saturday’s matchup against the Yankees after vehemently arguing calls with the officiating crew in the first inning.
