Mariners Game Today: Live Score, TV Channel, Starting Lineups & How to Watch Seattle’s Must-See Showdown

The Seattle Mariners host the Baltimore Orioles this afternoon at T-Mobile Park, with first pitch scheduled for 1:10 p.m. PT (4:10 p.m. ET) in the finale of a three-game set that could widen Seattle’s slim grip on first place in the AL West. Probable pitchers • Mariners: RHP Shane Baz (3-2, 3.58 ERA) makes his seventh start since returning from elbow surgery. The 27-year-old has held opponents to a .212 average and fanned 37 in 33 innings, but command lapses (12 walks) have pushed up his pitch counts. • Orioles: RHP Kyle Bradish (4-4, 4.00 ERA) owns a 1.15 WHIP and has spun at least six frames in five straight outings. He punched out 10 Mariners the last time he faced them in 2024. What’s at stake Seattle (38-36) leads Oakland by 1.5 games in a jumbled division race, while Baltimore (34-40) is fighting to stay within shouting distance of the AL East Wild Card picture. A series win would give the Mariners their fourth consecutive home series victory and keep momentum rolling into a weekend showdown with Boston. Key storylines to watch • Julio Rodríguez, listed day-to-day after crashing into the wall Tuesday, is back atop the lineup. His .921 OPS at T-Mobile is the team’s best among qualified hitters. • Seattle’s bullpen owns a 2.89 ERA since June 1. Look for Andrés Muñoz and Matt Brash in late innings if Baz exits early. • Gunnar Henderson’s leadoff homer Wednesday snapped a 2-for-20 skid for the O’s shortstop; containing his left-handed pop is priority one for Baz. How to watch & stream • TV: Root Sports Northwest (SEA market); MASN (BAL market) • Streaming: Mariners.TV on MLB.TV (in-market access, no cable required); out-of-market on MLB.TV and participating OTT platforms • Radio: Seattle Sports 710 AM; Orioles Radio Network Weather & conditions Forecast calls for partly cloudy skies and 65 °F (19 °C) at first pitch, with light west winds—favorable for pitchers who keep the ball on the ground. Stat of the day Seattle is 26-4 this season when scoring at least four runs, but just 12-32 when held to three or fewer, underscoring the need for early offense against Bradish’s heavy-slider mix. Bottom line With a division lead on the line and a sellout crowd expected for Kids Appreciation Day, the “Mariners game today” offers playoff-race stakes, a high-octane pitching duel, and multiple ways to watch—exactly the recipe to keep Seattle surging and search engines buzzing.
