AL West Winner Odds & Predictions 2025: Is it Time to Count the Houston Astros Out?

• Julio Rodriguez is batting .293 with four home runs in August

• Josh Hader was placed on the 15-day IL with no timetable to return

• Hunter Brown is 1-2 with a 4.46 ERA since July 1

After a busy trade deadline, the Seattle Mariners now sit atop the AL West standings with the Houston Astros. The team has been one of the hottest in baseball, though the dominance of the Milwaukee Brewers has somewhat overshadowed their success. With less than two months remaining in the season, will this be the year the Astros' AL West dominance finally ends?

MLB AL West Winner Predictions

We hope you locked the Mariners in when we told you, because BetMGM has finally installed them as the betting favorite to win the AL West. As of the time of this writing, Seattle has won eight straight games and ten of their previous 11. They are 16-8 since the All-Star break, leading them to tie the Astros atop the division.

Houston really seemed to have enough to win the AL West for the fifth-straight season, but they have been hit hard by injuries. They lost their top hitter a couple of weeks ago in Isaac Paredes, who appears to be set to miss the remainder of the season. While their rotation is finally getting healthy, elite closer Josh Hader has landed on the IL and seems likely to miss more than the two weeks required. 

Another big concern for the Astros is Cy Young candidate Hunter Brown (9-5, 2.51 ERA, 0.98 WHIP). While his season numbers remain fantastic, he has delivered just one quality start over his last six games, going 1-2 with a 4.46 ERA during that run. The Astros don’t have the depth for him to regress, putting their division hopes in even more doubt.

While they sit 6.5 games behind the Mariners and Astros, you still can’t count out the Texas Rangers. Their hot streak came to an end over the last week as the offense cooled off. With an elite rotation, solid bullpen, and red-hot Corey Seager, don’t be surprised if the Rangers climb their way back into this race.

MLB AL West Winner - My Pick

Seattle Mariners (+130) at BetMGM Sportsbook

Seattle certainly has momentum on their side, but we also believe they have the better roster. Josh Naylor has been fantastic since joining the Mariners, and Eugenio Suarez will get going soon. Julio Rodriguez has also gotten hot in August, with a .293 average and four home runs. If he can continue to see the ball well, this lineup could be dominant down the stretch.

With Seattle’s rotation remaining one of the best in baseball, Seattle is the only AL West bet to make.
