Daikin Park (formerly Minute Maid Park), Houston, Texas
First pitch: 7:20 p.m. ET (Sunday Night Baseball)
TV: NBC / Peacock
Venue and Weather Forecast
Daikin Park is a retractable-roof stadium known for being relatively hitter-friendly, especially with the short left-field porch. Current forecast: Sunny and hot with highs around 98°F, heat index values up to 106, light south/southeast winds around 5–12 mph, and no precipitation expected. Extremely warm conditions for an evening game; the roof may be closed for comfort.
Probable Starting Pitchers
Mariners: RHP Bryan Woo (8-8, 4.15 ERA, 1.10 WHIP, 132 strikeouts in 132.1 IP). Solid control pitcher with a low walk rate. Has shown the ability to go deep into games and limit hard contact.
Astros: RHP Hunter Brown (3-2, 3.68 ERA, 1.27 WHIP, 67 strikeouts in 63.2 IP). Strong stuff with a solid ERA in limited innings this season. Has been effective when healthy and provides a slight edge in pure ERA.
Listed Injury Reports
Mariners: Taylor Ward (day-to-day, quadriceps); J.P. Crawford (10-day IL, wrist); Colt Emerson (10-day IL, wrist); Luke Raley (out longer-term, elbow/forearm); Cole Wilcox (15-day IL, oblique); Matt Brash (15-day IL, lat, progressing); longer-term absences include Carlos Vargas, Will Wilson, and others on the 60-day IL. Infield and outfield depth are affected.
Astros: Mike Burrows (15-day IL, elbow, on rehab); Brice Matthews (10-day IL, knee); Carlos Correa (60-day IL, ankle surgery); Brandon Walter (60-day IL, elbow). The absence of Correa remains a notable defensive and offensive loss, though the lineup has adapted.
Current Rosters / Key Players
Mariners standouts: Julio Rodríguez, Randy Arozarena, Cal Raleigh, Josh Naylor, Cole Young (hot recently), Dominic Canzone. Offense has been inconsistent overall (lower run production) but capable of big nights, as shown in Saturday’s 10-5 win. Strong pitching staff ERA ranks well.
Astros standouts: Yordan Alvarez (elite production), Jeremy Peña, Jose Altuve, Isaac Paredes, Christian Walker, Daulton Varsho. Power-oriented attack (high team home-run total) and solid home performance.
Key Player vs. Player Matchups
Woo’s strong control and ability to induce weaker contact will be tested by Houston’s power core, particularly Alvarez. Brown faces a Mariners group that can put together big innings when hitting for average and power simultaneously. Daikin Park’s dimensions and the hot weather can favor fly-ball hitters. Both right-handers create interesting platoon dynamics.
Recent Team Forms
Mariners: 58-66 overall (third in AL West); 25-37 on the road; 3-7 in last 10. Won Saturday 10-5 to even the series after dropping the opener. Have dominated the season series against Houston.
Astros: 63-61 overall (first in AL West); 31-30 at home; 5-5 in last 10. Dropped Saturday’s game after winning Friday in extras. Fighting to hold the division lead.
Series History
Mariners have owned the season series, winning the majority of prior matchups (including a strong early-season mark). The current three-game set is split 1-1 heading into the finale. Seattle aims to take the series; Houston looks to split and protect its slim AL West lead.
Betting Trends
Houston’s home edge and Brown’s ERA edge make them slight favorites, but Seattle’s strong season-series history and recent offensive explosion create value on the underdog. Hot weather and the park lean slightly toward scoring, though both starters can keep games competitive.
The Astros enter as slight home favorites with the better pure ERA starter in Brown while trying to protect their AL West lead, while the Mariners look to capitalize on their strong season-series history and recent offensive surge to take the series. Expect a competitive Sunday Night Baseball contest under hot Houston skies. Check official sources for confirmed lineups and any late updates.
