It's Finally Here: Mariners Open Season Against Cleveland at T-Mobile Park Tonight
The wait is over. After months of spring training and endless offseason debates, the Seattle Mariners are ready to throw the first pitch of 2026. Tonight at T-Mobile Park, the Guardians roll into town for the season opener, and you better believe this crowd is going to be loud.
First pitch is at 10:10 p.m. EDT, and the Mariners are favored going in. Logan Gilbert takes the mound for Seattle against Cleveland's Tanner Bibee, both throwing zeros on the season record. This is the moment. No more what-ifs. No more hypotheticals. Baseball is back in the Emerald City.
What Seattle Brings to the Table
The Mariners finished last season at 90-72 overall, and they were absolutely dominant at home with a 51-30 record. That's the kind of home field advantage that matters in October, and the M's will lean on that tonight. Offensively, Seattle averaged 8.3 hits per game last year while posting a .244 batting average. The bats need to stay hot if the Mariners want to make a run.
But there's a catch. The injury report is already piling up. Miles Mastrobuoni is on the 10-Day IL with a calf issue. J.P. Crawford is sidelined with a shoulder problem. Bryce Miller is dealing with an oblique and will miss 15 days. Logan Evans is out long-term on the 60-Day IL with an arm injury. That's a lot of bodies missing on opening day, and depth is going to be tested early.
Cleveland Comes Ready
The Guardians are no joke. They finished 88-74 last season and went 43-38 on the road. They averaged 2.6 extra base hits per game, and they're hitting home runs at a clip of 1.0 per game. Bibee takes the ball for Cleveland, and he'll be looking to keep the Mariners quiet early.
Cleveland's dealing with some injury headaches too. George Valera is on the 10-Day IL with a calf strain. Andrew Walters and Hunter Gaddis are both out 15 days with lat and forearm injuries respectively. Both teams are limping into this one, which means the teams that can stay healthy will have the edge.
What's at Stake Tonight
This is Game 1 of a seven-game series spread across the season. The Mariners host the first four games here at T-Mobile Park starting tonight, then they head to Cleveland for three more in late June. Every win matters in April, and momentum is real. Get off on the right foot, and you ride that energy deep into the season. Drop this one, and the noise starts immediately.
Tickets are available starting at $42. Get loud tonight, 12s. Let's go Mariners.
