Key dates for the 2026 Mariners season
With a 162-game schedule, watching the Mariners can feel like a roller coaster at times. After reviewing the 2026 calendar, I’ve mapped out several impactful stretches that will define the team’s hunt for another division title.
- Home Opener (March 26): The Mariners begin their 50th franchise season at T-Mobile Park with a high-profile series against the Cleveland Guardians.
- AL West matchups: You’ll want to keep a close eye on games against the Houston Astros, Texas Rangers, Los Angeles Angels, and Athletics. Divisional play is always intense, but with Seattle defending the AL West crown, these matchups carry even more weight this year.
- MLB All-Star Week (July 11–14): There were three Mariners in the 2025 All-Star Game. If the team remains in contention, you’ll likely see multiple players represented at Citizens Bank Park in Philadelphia for the 2026 Midsummer Classic.
- MLB Trade Deadline (Aug. 3): If the Mariners believe they are just a move or two away from a World Series run, keep a close eye on the front office leading up to the Monday, August 3 deadline.
Best T-Mobile Park promotional nights in 2026
Mariners games are always fun, but they’ll have a special flair this season as the franchise celebrates its 50th year. You’ll want to keep a close eye on the Mariners promo schedule so you don’t miss out on these limited-edition collectibles.
Fans will want to be in the stands for Randy Johnson’s Jersey Retirement on May 2. Every month or so, the team will give away a pin honoring a particular decade of Mariners baseball. To that end, 50 Seasons Celebration Night is on August 8.
