The Mariners will open the season at home against the Boston Red Sox on March 25 and finish the season on September 26 in West Sacramento, California, against the Athletics.

Offseason

After finishing the 2025 season in third place in the American League West and with a losing record for the first time since 2020, manager Dan Wilson stepped down and many coaches were not retained. The team announced days after the season ended that bench coach Manny Acta, hitting coach Kevin Seitzer, infield coach Perry Hill, and first base coach Eric Young Jr. would not return in 2027.

Transactions

• October 2, 2026: Claimed Michael Toglia off waivers from the Cincinnati Reds.
