Seattle will try to stretch its winning streak to eight when the Mariners visit the Baltimore Orioles in a key American League showdown on Tuesday at Camden Yards. Seattle, riding a 9-1 run over its last 10 games, sits at 66-53 and is 29-28 on the road this season. Baltimore stands 53-65 and 28-29 at home in 2025, and has won six of the past seven meetings with Seattle.
First pitch is scheduled for 6:35 p.m. ET. The Mariners have been successful against the Orioles lately, and Seattle carries momentum into this matchup as it chases continued improvement down the stretch of the season.
Projected starters feature a pair of veterans at Oriole Park: George Kirby (7-5, 4.04 ERA) will start for Seattle after a string of solid performances, including an 8-6 win over the White Sox last week in which he worked six innings with two earned runs allowed. For Baltimore, Dean Kremer (8-8, 4.35 ERA) takes the mound after a tough outing in his most recent start.
Offensively, catcher Cal Raleigh has been a driving force for Seattle. In 116 games this season, Raleigh is batting .247 with 16 doubles, 45 home runs, 98 RBI and 78 runs. He’s riding a three-game hitting streak, homering in each of the weekend’s three games against Tampa Bay. Against Baltimore this season, Raleigh has gone 4-for-12 with a homer and four RBIs in limited action this year.
For the Orioles, shortstop Gunnar Henderson has been a bright spot, collecting hits in eight of 10 games and delivering multiple hits in several recent outings. Henderson went 3-for-9 with a homer and three RBIs in Baltimore’s weekend series against Oakland and has shown pop and run-producing ability in recent matchups.
Vegas and betting markets list Seattle as the favorite here, with the Mariners around the -158 money-line range and the over/under set near 9 runs. The latest projections from the prevailing MLB analytics model suggest a high-scoring game, with a projection around 9.7 combined runs, signaling that offenses could have the edge in this matchup.
Why Seattle can win: Kirby has been a steady force for the rotation, delivering strong work across his starts as Seattle looks to continue its recent success. Raleigh’s power at the plate provides a critical middle-to-late lineup boost, and Seattle will look to keep Baltimore’s offense in check with timely pitching and defense.
Why Baltimore can win: Kremer gives Baltimore a reliable chance to keep Seattle’s scoring in check and flip the game with a strong start. Henderson’s recent run-producing ability and the Orioles’ depth in the lineup could spark a weekend turnaround and help Baltimore’s offense support a potential upset at home.
How to watch and what to watch for: The clash begins at 6:35 p.m. ET at Camden Yards. Look for Seattle to lean on Kirby to extend the rotation’s late-season success, while Baltimore will rely on Kremer to stabilize the mound and generate enough offense to support the bullpen.
Summary: Seattle heads to Baltimore hoping to keep rolling and extend its winning streak, while the Orioles aim to surface a strong home performance to turn around a challenging stretch. With Kirby on the mound for Seattle and Kremer for Baltimore, this game could hinge on timely hitting from Raleigh and Henderson as well as the ability of each starter to work deep into the game.
Positive note: If Seattle continues its recent form, short-term momentum could help them strengthen their position as the season progresses, keeping pressure on opponents in the tightly packed American League standings.
