Starting Pitchers Ready for the Series Finale
Luis Castillo is expected to start for Seattle. Castillo enters with a 0-4 record, 6.57 ERA, and 1.62 WHIP over 38.1 innings. He has allowed 49 hits while recording 37 strikeouts, 13 walks, and six home runs. Houston is projected to counter with Mike Burrows, who carries a 2-4 record with a 5.04 ERA and 1.48 WHIP across 44.2 innings. Burrows has allowed 52 hits while striking out 42 batters, walking 14, and surrendering eight home runs. 
Mariners Looking to Continue Offensive Momentum
Seattle enters this matchup with a 21-22 overall record and a 9-11 road record. The Mariners recently won over Houston 10-2 and recently won over Houston 3-1 to begin this series. Before that, Seattle recently lost to Chicago 2-1 and 6-1 but recently won over Chicago 12-8. The Mariners have shown flashes of strong offense during this stretch, particularly in games where the power hitting has been active.
The Mariners are batting .231 as a team with 180 runs, 327 hits, and 49 home runs. Seattle owns a .320 on-base percentage and a .380 slugging percentage. On the mound, the Mariners have been solid statistically with a 3.67 ERA and 1.22 WHIP while allowing opponents to hit .253 against them. Seattle pitchers have also collected 370 strikeouts while issuing only 105 walks.
One major strength for Seattle has been the pitching control. The Mariners have issued significantly fewer walks than Houston while also carrying the lower ERA and WHIP. That ability to limit free baserunners has helped Seattle stay competitive even when the offense has gone through quieter stretches.
Astros Trying to Halt a Difficult Stretch
Houston enters this contest with a 16-27 overall record and a 9-12 home record. The Astros recently lost to Seattle 10-2 and recently lost to Seattle 3-1. Before that, Houston recently lost to Cincinnati 5-0 and 3-1 before finally recently winning over Cincinnati 10-0. The Astros have struggled to maintain consistency over the last several games, especially offensively during the current losing stretch.
Houston is batting .255 as a team with 199 runs, 373 hits, and 52 home runs. The Astros hold a .330 on-base percentage and a .421 slugging percentage. On the pitching side, Houston owns a 5.61 ERA with a 1.59 WHIP while allowing opponents to hit .263 against them. Astros pitchers have also recorded 374 strikeouts while issuing 217 walks this season.
Houston’s biggest strength remains offensive production. The Astros hold advantages in batting average, total runs, hits, home runs, on-base percentage, and slugging percentage compared to Seattle. However, the pitching numbers remain a concern, especially with the high ERA, WHIP, and walk totals entering this matchup.

Seattle Mariners vs Houston Astros Picks and Prediction
Seattle Mariners vs Houston Astros Pick
- Pick: Seattle Mariners Moneyline
Seattle looks like the stronger side entering this matchup after consecutive wins over Houston in the series. The Mariners hold a clear advantage on the mound statistically with a much lower team ERA and WHIP, while also allowing fewer walks overall. Seattle has already outscored Houston 13-3 across the first two games of the series, and the Astros continue to struggle defensively and on the mound. Even with Houston’s offensive numbers being strong overall, Seattle’s pitching profile gives the Mariners the edge.
Seattle Mariners vs Houston Astros Total Pick
- Pick: Over 8.5
I would lean toward the over in this matchup because both starting pitchers enter with ERAs above 5.00, and Houston’s pitching staff has struggled all season with a 5.61 ERA and 1.59 WHIP. Seattle has already scored 13 runs across the first two games of the series, while Houston still carries strong overall offensive numbers despite the recent losses. With both teams capable of generating power offensively and the pitching matchup showing vulnerability, this game has a good chance to produce steady scoring.
Final Score Prediction: Seattle Mariners 6 – Houston Astros 4
