Seattle Mariners 2026 Spring Training Schedule

This is a tentative schedule. Home games in bold. SS = split squad. All time local. Still to come: broadcast schedules.

The Seattle Mariners share spring training digs with the San Diego Padres at Peoria Stadium, which was significantly upgraded before the beginning of spring training in 2015. The ballpark also underwent some more changes before spring training in 2016 and 2017, including the addition of a kids’ play area.

Peoria Stadium is considered by many to be among the best ballparks in the Cactus League, despite being one of the oldest these days. The Seattle Mariners and the San Diego Padres share the ballpark, so a visit to Peoria – a suburb of Phoenix – during any point in spring training will undoubtedly find a game going on, but recent renovations tightened the supply of tickets available for most dates.

The complex was the first MLB spring-training facility shared by two teams. (There had been situations where two teams played games in the same ballpark, but they maintained separate training facilities.) Today, of course, almost every new training camp in the Cactus League is built for two teams.

The Peoria Sports Complex contains Peoria Stadium, two 40,000-square-foot clubhouses, indoor and outdoor batting tunnels, 12 major-league-sized practice fields (two lighted), and four half fields. The extensive facility allows both teams and their minor-league squads to practice simultaneously.
