Mariners Keep Beating Astros But Their Season Is Still Falling Apart

Once contenders with high hopes, the Seattle Mariners' season falters amid offensive struggles and missed opportunities, leaving fans frustrated with a dashed playoff dream.

The Seattle Mariners’ season has gone off the rails in a way nobody in that dugout could’ve wanted, especially after all the preseason hype that had them pegged as an AL West contender and even a possible World Series team.

Before the first pitch, the Mariners were a trendy pick to take the division. ESPN had them as the biggest threat to the Los Angeles Dodgers’ title reign, and the network also projected Julio Rodriguez as the 2026 AL MVP. Sports Illustrated was just as bullish, forecasting a division crown, a World Series trip, and another AL MVP nod for Rodriguez.

That optimism looked justified early when Seattle kept hammering Houston. Mariners fans had every reason to talk after their club went 9-2 against the Astros this season, including a May beatdown that had Seattle believers dreaming big. Even after Houston stole a massive comeback win in the opener of an August series, the Mariners still took two of three and kept the rivalry edge on their side.

But the rest of the season never matched the head-to-head swagger.

Seattle’s trouble has been obvious for a while, and it really started showing up around the trade deadline. Fans were frustrated by how little the front office seemed willing to do, and the criticism has only grown louder as the losses piled up.

For a club that opened the year with World Series expectations, the deadline approach felt cautious at best. Last year’s additions of Eugenio Suarez and Josh Naylor stood out because Seattle actually pushed then.

This time, the message was basically the opposite: they knew they needed help and did almost nothing.

That hesitation looks even worse given where the team sits now. The Mariners are dead last in the American League in runs scored and in batting average with runners in scoring position.

On top of that, they’re tenth in the AL in pitching ERA, a sharp drop for a staff that was once the backbone of the franchise. Seattle had the best ERA in the AL in 2024, slipped to sixth in 2025, and has now fallen to tenth.

And despite all that dominance over Houston, the division race is over. Seattle is nine games under .500, six games back in the division with 15 games left, and there’s no realistic path to catching the Astros.

The last two games against Houston won’t matter for Seattle’s playoff hopes. The Mariners are also five games out of a wild card spot and sit behind five other teams.

So even with the one thing they’ve done well - beating the Astros - the bigger picture is brutal. Seattle had the hype, the favorable predictions, and the rivalry edge. What it didn’t have was enough offense, enough pitching, or enough urgency to turn any of it into a season that lasted.

Astros Playoff Push Now Rests On Four Slumping Contributors

As the Astros try to stay in the AL West race and protect their playoff position, a few familiar names have become part of the conversation for the wrong reasons. Jeremy Pena has been fighting through a slump since early August, Yordan Alvarezs power has been quieter since late July, and Bryan Kings uneven run on the mound has already led to a demotion before a recent recall. For a team that has leaned on production from all over the roster, those stretches have made the margin for error feel a little smaller.

Steven Okert adds another layer to the picture because his job has become one of the more important ones in the bullpen. The left-hander has been used as a stopper and setup man, which means Houston needs him steady in the spots that can swing games late. If the Astros are going to keep pressing toward the division title, they will need those four contributors to look a lot more like themselves than they have lately. [Read more 🡒]

Astros Offseason Uncertainty Now Includes Tatsuya Imais Next Decision

Tatsuya Imais first season in Houston has not gone the way anyone around the club expected, and the Astros now have another winter question hanging over their roster picture. After struggling enough to be moved to the bullpen, the veteran right-hander has not just become a performance issue, but also a contract storyline, with his two-year, $36 million deal suddenly part of the broader uncertainty facing the team.

ESPNs Jeff Passan has already weighed in on what comes next, predicting Imai will stay put rather than opt out and test the market. The reasoning is straightforward enough: with a 5.20 ERA overall and better results in relief than in the rotation, it is hard to see a cleaner path to a richer offer elsewhere. For the Astros, the next chapter is less about whether Imai has talent and more about whether a rebound can turn this from a difficult season into a salvageable investment. [Read more 🡒]

Jeremy Pea Just Became A Real Astros Offseason Dilemma

With Dana Brown gone and Jim Crane still hunting for a new general manager, the Astros are already navigating an offseason that could shape more than just the front office. Even while they sit atop the AL West, the decisions ahead are the kind that reach well beyond the standings, especially when it comes to players who have become central to the clubs identity and long-term planning.

Jeremy Pea has quickly moved into the center of that conversation. MLB.coms Mark Feinsand has identified the shortstop as a top trade candidate this winter, particularly if Houston cannot work out an extension before he gets to free agency. For an organization trying to balance present contention with whatever comes next under a new GM, that is the sort of dilemma that tends to linger until it is finally resolved. [Read more 🡒]
