The Mariners head to Houston on Monday for a four-game series against the Astros, carrying both a reminder of how quickly baseball can change and a chance to reset after a strange weekend in Chicago. Seattle scored 12 runs on Friday, then managed only two runs total over the final two games.
That slump has not knocked the Mariners off the board. Seattle is still the favorite to win the division and holds the third highest playoff odds in the AL, but the margin for error is getting thinner as the schedule tightens and the mariners - astros matchup arrives again.
The last time these clubs met, Seattle swept Houston in four games, a clean run that showed how far the gap can swing from one week to the next. This series now gives the Mariners a chance to prove that stretch was not a one-off, while the Astros try to keep pace despite a roster that has been battered almost nonstop.
Houston has 15 players on the injured list, the most of any team in the majors. Carlos Correa hurt his ankle last week and is out for the season, Hunter Brown, Cristian Javier and Josh Hader are working through significant injuries, and six other pitchers have been sidelined with minor issues. The Astros have still scored the second most runs in the AL this season, powered by Yordan Alvarez’s career-high 188 wRC+ and Christian Walker’s nine home runs and 143 wRC+.
The lineup has been forced to carry more than its share of the load. Isaac Paredes has been covering third base while Correa was handling shortstop for the injured Jeremy Peña, and Brice Matthews and Zach Cole have provided steady work in the outfield while Jake Meyers and Joey Loperfido have been out. That is the tension in Houston: an offense good enough to stay dangerous, but a roster thin enough that one more injury can change the shape of the series.
There are also signs the Astros have tried to patch holes creatively. Peter Lambert signed a minor league deal with Houston this offseason after a stint with the Yakult Swallows of NPB, and he has looked pretty solid across four starts this year. The right-hander also developed a straight cutter in Japan, one of several small adjustments that have helped keep him in the mix. Houston signed Tatsuya Imai to a three-year deal this offseason, even as questions followed how his fastball and slider would translate against MLB hitters. His slider has the least amount of horizontal movement of any slider thrown in the majors, the kind of detail that matters if the Astros are to squeeze value out of every arm they have left.
The Mariners do not have to win the division this week, and they are not in major trouble even after the recent wobble because the AL has been described as uninspired. But Houston is still the place where the race can tilt, especially against an opponent that has been near the bottom of the AL West for much of the season and has little room to absorb more damage.
