Ryan Mountcastle was forced to watch on as the Baltimore Orioles secured a second-straight win, jumping to 8-7 on the 2026 MLB season after a 6-2 win over the San Francisco Giants on Sunday, winning the series 2-1. Now, the Orioles will remain in Baltimore as the Arizona Diamondbacks come to town beginning on Monday. Mountcastle has been the primary starting first baseman for the Orioles in recent years, but with the addition of former New York Mets star Pete Alonso over the offseason, his everyday role at the position has significantly decreased.
