Who won Seattle Mariners vs Houston Astros?
Seattle Mariners beat Houston Astros 7-3 at Daikin Park on September 21, 2025.
The Seattle Mariners secured a decisive 7-3 victory against the Houston Astros at Daikin Park, continuing their strong performance in the latter part of the season. This win allowed the Mariners to clinch the series 4-3 against the Astros, showcasing their dominance in recent matchups. The Mariners have been in impressive form, boasting a record of 9-1 over their last ten games, with an average of 5.0 runs scored per game while allowing only 2.9 runs. Their recent winning streak includes two consecutive victories, with their last game resulting in a commanding 4-0 win over the Astros just a day prior to this matchup.
In contrast, the Astros have struggled recently, finishing their last ten games with a record of 6-4. They averaged 4.3 runs scored and allowed 3.9 runs during this stretch. The Astros' performance has been inconsistent, highlighted by their recent loss to the Mariners, which marked their first defeat in the series after winning three consecutive games against the Texas Rangers prior to facing Seattle.
The game featured significant scoring plays, particularly in the second inning when the Mariners took control. Robles walked to bring in Polanco, followed by a home run from Crawford that scored three additional runs. Raleigh capped off the inning with another homer, putting the Mariners ahead 7-0 early in the game. The Astros managed to respond with a home run from Cole in the third inning, but they could not close the gap significantly. Altuve and Paredes added runs for Houston later in the game, but it was not enough to overcome the Mariners' lead.
In terms of home and away performance, the Astros have a home record of 3-1 in their last four games at Daikin Park, while the Mariners have excelled on the road with a 3-1 record in their last four away games. The Mariners' success away from home has been a crucial factor in their overall strong season, as they continue to push for a playoff position.
Injuries have impacted both teams, with the Astros missing key players such as Brice Matthews, Mike Burrows, and Carlos Correa, all of whom are on the injured list. The Mariners also face challenges with Brendan Donovan and Cole Wilcox among others sidelined. The absence of these players has forced both teams to adapt their lineups, affecting their strategies and overall performance.
The betting market reflected the Mariners' strong form leading into this game, with odds favoring them as the away team. The Astros, despite being at home, were seen as underdogs, with a home win probability of 0.0 according to the final market analysis. This indicates a lack of confidence in their ability to secure a win against a surging Mariners team.
Weather conditions at Daikin Park were favorable for baseball, contributing to a lively atmosphere as fans witnessed an exciting matchup. As the season progresses, both teams will need to address their injury concerns and find ways to maintain performance levels, particularly as they head into the final stretch of the regular season. The Mariners' ability to capitalize on scoring opportunities and the Astros' need to improve their offensive consistency will be key factors to watch in their upcoming games.
