Athletics 2B Zack Gelof Faces Season-Ending Left Shoulder Surgery After Injury

Athletics second baseman Zack Gelof is expected to undergo season-ending surgery on his left shoulder after dislocating it during a game against the Pittsburgh Pirates. This injury adds to an already difficult 2025 season for Gelof, who missed the first three months due to a fractured hamate bone and a stress reaction in his rib cage. Since returning on July 4, Gelof struggled at the plate with a .174 batting average, two home runs, and a .502 OPS over 30 games. Manager Mark Kotsay praised Gelof's relentless defensive effort but acknowledged the setback and the need for rehab during the offseason. With Gelof sidelined, Darell Hernaiz has taken over second base for the remainder of the season. Gelof's future as a regular starter is uncertain, especially with promising prospects like Leo De Vries and Jacob Wilson potentially reshaping the Athletics' infield plans.
