Seattle Mariners Release 2026 Season Schedule Including Doubleheader

The 2026 MLB schedules for the Seattle Mariners and Baltimore Orioles have been released, highlighting key matchups and challenges ahead. The Mariners will open their season at home against the Cleveland Guardians, followed by the New York Yankees, and have a rare home doubleheader against the Boston Red Sox on June 20, scheduled around the World Cup games in Seattle. Their late-season schedule is less travel-intensive, with no games east of Denver in the final 22 contests, ending at home against the Houston Astros and Los Angeles Angels. The Orioles begin their season hosting the Minnesota Twins and Texas Rangers before their first road trip to face the Pittsburgh Pirates, with a critical stretch after the All-Star break involving series against top teams like the Houston Astros, Boston Red Sox, Atlanta Braves, and Philadelphia Phillies. Baltimore's roster construction centers on Samuel Basallo after a major midseason fire sale and managerial change, aiming for contention in 2026 despite a grueling schedule. Both teams face strategically important schedules that could shape their playoff prospects, with the Mariners balancing baseball with the World Cup event and the Orioles enduring a tough post-All-Star schedule to prove their competitiveness.
