AL West preview: Seattle Mariners looking for their first World Series title

The Astros had been a mainstay atop the AL West for eight years — claiming seven division titles during that time — but now the division appears to be under new management.

Last season, the upstart Mariners finally broke through after years of promise, winning 90 games and claiming their first division crown since 2001. This season, the club hopes to take the next step forward and reach the World Series for the first time in franchise history. Seattle locked up cleanup man Josh Naylor to a five-year, $92.5-million contract, solidifying their lineup. The M’s also traded for super utilityman Brendan Donovan, who, as a member of the St. Louis Cardinals, was named an All-Star for the first time in his career last season.

The Astros, in their third year under manager Joe Espada, are hoping to return to the top of the division. They’ll have their work cut out for them, with just seven players remaining from the Astros’ 2022 World Series team.

Even after a pair of mediocre seasons, the Rangers remained aggressive this winter, making a pair of blockbuster trades, acquiring frontline starter MacKenzie Gore from the Nationals and outfielder Brandon Nimmo from the Mets. Ex-Marlins manager Skip Schumaker will take the reins from four-time World Series champion Bruce Bochy, who did not return as the club’s skipper.

Entering their second season playing in Sacramento, the Athletics grabbed veteran Jeff McNeil from the New York Mets in a trade, while locking up promising youngsters Tyler Soderstrom and Jacob Wilson to long-term extensions. The Angels installed rookie manager Kurt Suzuki, replacing Ron Washington.

After bidding farewell to Eugenio Suárez and Jorge Polanco, the Mariners are betting on young infielders Cole Young and Colt Emerson. Newcomer Brendan Donovan should provide a nice spark to the M’s lineup. 26-year-old Bryan Woo emerged as the club’s ace last season while George Kirby missed the first two months with shoulder inflammation and was never quite right. A healthy Kirby could make a huge difference this season for an already formidable M’s rotation.

Even after an offseason in which the Astros lost stars Kyle Tucker, Alex Bregman and Justin Verlander, the team still led the West for most of the season in 2025. One player to watch will be second-year outfielder Cam Smith, who the Astros acquired as the centerpiece of the Tucker trade. It was a tale of two seasons for Smith, who dazzled with a .297/.357/.443 slash line through his first 75 big league games, but hit a snag over his next 59 games, slashing just .153/.248/.232.

2025 | 76-86, 4th in West

Last year in playoffs | 2020

Two years after losing 112 games, the A’s showed encouraging progress in their first season in Sacramento. First baseman Nick Kurtz ran away with AL rookie of the year honors, winning the award unanimously, with shortstop Jacob Wilson placing second. Between Kurtz (36), catcher Shea Langeliers (31), designated hitter Brent Rooker (30), left fielder Tyler Soderstrom (25) and right fielder Lawrence Butler (21), the A’s had five players hit for 20 or more homers last season.

4 | Texas Rangers

2025 | 81-81, 3rd in West

Last year in playoffs | 2023

The Rangers have posted just one winning season over the last 10 years, and it came in 2023, the same year that the club won its first-ever World Series. In order for new manager Skip Schumaker to return the Rangers to form, he’s going to need his position players to bounce back in a big way. Freshly-acquired MacKenzie Gore should add length to the Rangers’ rotation, while former Vanderbilt teammates Jack Leiter and Kumar Rocker will have an opportunity to establish themselves as formidable major league starters.

5 | Angels

2025 | 72-90, 5th in West

Last year in playoffs | 2014

The Angels upped their win total by nine games from 2024 to 2025, and the club could continue to progress in its first season under rookie manager Kurt Suzuki. General manager Perry Minasian enters the final year of his contract, after the Angels failed to post a winning record in each of his first six seasons.
