MLB AL West Season Recap

To the surprise of no one, adding offense elevated the Seattle Mariners in 2025. Randy Arozarena, whom they acquired last summer, returned to form to smack 27 home runs and steal 28 bases. The team added a couple of dangerous bats this year in Eugenio Suarez and Josh Naylor, who both helped them win the AL West for the first time in almost 25 years.

Those bats have turned the offense around, helping them rank tenth in the league with 745 runs scored, despite ranking 20th in batting average (.244). However, none have been as important as AL MVP favorite Cal Raleigh. The catcher has smashed several records with 58 home runs. 121 RBIs, and 14 stolen bases. His breakout performance drove the offense, which improved as the season progressed.

This division race was decided after the Mariners and Astros series last weekend. The Mariners went on the road and swept their rival, ending the division race once and for all. The offense hammered Houston’s top three starters, while the trio of Woo, Kirby, and Gilbert delivered on the mound. 

There is plenty of blame to go around in Houston, but injuries helped nail the coffin shut on their division title hopes. The team’s most dangerous bat, Yordan Alvarez, was limited to just 48 games by injuries. Elite close Josh Hader also landed on the IL down the stretch, the latest in a long line of pitchers to do so. 

The Texas Rangers forced themselves into the AL West and Wildcard races in the second half of the season, but an eight-game losing streak ended those hopes. It negated an incredible run the team made in August, wasting a year of a healthy Jacob de Grom in the process. 

It appears the Rangers have pitching to build around, but the offense remains a massive problem. Corey Seager is a great player, but he struggles with staying healthy, playing just 102 games so far this season. 

While the Rangers have some young bats they hope will develop, there is concern over the future of Adolis Garcia. The 32-year-old slugger hit 39 home runs and drove in 107 RBIs during the team’s 2023 World Series season. However, he finished this year with 18 homers and 74 RBIs. Those are on pace to be his lowest season totals since becoming a full-time starter in 2021.
