With Astros vulnerable, can Mariners dethrone them in AL West?

Slowly but surely, the stars of the Houston Astros’ 2017 World Series-winning team have scattered about in the years since.

Seattle Mariners’ next big prospect decision is more complicated

George Springer is in Toronto now, Alex Bregman in Boston and Carlos Correa in Minnesota. Justin Verlander pitches for San Francisco. Jose Altuve and Lance McCullers Jr. are still with the Astros, but it feels like it’s only a matter of time before Houston’s dominance of the AL West comes to an end.

The question is whether anyone else in the division has what it takes to force a changing of the guard.

If it weren’t for Oakland’s division title in the pandemic-shortened 2020 season, Houston would have a streak of seven straight AL West championships. Only the Braves, Dodgers and Yankees have had runs that long since divisional play began. But last year, the Astros won just 88 games, their fewest in a full season since 2016. Only the mediocrity of the rest of the division kept them on top.

This year, Houston is 32-27, which puts the Astros on pace to win 88 games again. Nonetheless, they trail the first-place Seattle Mariners by just a half-game.

Astros slugger Alvarez’s injury worse than initially thought

The challengers all have their problems. The Athletics had an encouraging start but have lost 17 of their last 18. The Los Angeles Angels look headed to a 10th straight losing season. Texas won it all as a wild card two years ago but has been one of the worst offensive teams in baseball in 2025.

That leaves Seattle. The Mariners have the major league home run leader in Cal Raleigh — yes, he’s ahead of both Shohei Ohtani and Aaron Judge with 23.

Seattle also has Bryan Woo and Luis Castillo leading the pitching staff, but its team ERA is pretty middling at 3.86. All-Star and opening day starter Logan Gilbert missed all of May with an elbow issue.

The Mariners haven’t won a division title since 2001. It’s there for the taking right now, but are they up to the task?

Trivia time

There are six current major league franchises that have never won back-to-back division titles. Who are they?

Agony of defeat

Boston was swept three straight at Milwaukee, with the last two losses coming in walk-off fashion. Christian Yelich hit a 10th-inning grand slam to beat the Red Sox on Tuesday night, and the following day Caleb Durbin ended it with a sacrifice fly.

Boston has lost a major league-high seven games in walk-off fashion — and those games account for over a fifth of their 32 defeats.

Line of the week

Junior Caminero went 4 for 5 with two homers, two doubles, five RBIs and four runs in Tampa Bay’s 16-3 rout of Houston on Saturday. Even after a loss Sunday, the Rays have won nine of their last 12 and are just a half-game behind Minnesota for the American League’s final wild card.

Comeback of the week

Minnesota trailed Seattle 6-3 with two outs in the top of the ninth Friday night when Willi Castro hit a two-run homer off closer Andrés Muñoz. Then Byron Buxton singled, stole second and scored on a single by Trevor Larnach.

In the top of the 10th, the Twins scored six runs on their way to a 12-6 victory. Seattle had a win probability of 98.9% in the ninth, according to Baseball Savant.

Muñoz had not allowed an earned run all season. He blew another save against Minnesota on Sunday but ultimately got the win.

Trivia answer

The Miami Marlins and Colorado Rockies have never won ANY division titles. The other four teams that have never gone back-to-back are:

• San Francisco Giants (NL West titles in 1971, 1987, 1989, 1997, 2000, 2003, 2010, 2012 and 2021)
• New York Mets (NL East titles in 1969, 1973, 1986, 1988, 2006 and 2015)
• Chicago White Sox (AL West titles in 1983 and 1993, AL Central titles in 2000, 2005, 2008 and 2021)
• Seattle Mariners (AL West titles in 1995, 1997 and 2001)
