The Seattle Mariners went into the All-Star break on a high note, winning six of their previous ten games. This allowed them to trim the Astros’ lead in the AL West to five games heading into the second half of the season. While this team has talent, does Seattle have enough to compete with a surprisingly great Houston Team?

MLB AL West Winner Predictions

The All-Star break came at a great time for the Houston Astros. After going 19-7 in June, the team has lost five of its previous six games. While the team’s hot streak finally ending isn’t a big surprise, an ever-growing list of injuries should have fans worried as we head into the season’s second half.

The most significant injury involves slugger Yordan Alvarez, who has been on the IL since early May. The star hurt his hand with what the team thought was a strain, but would prove to be a fracture. Reports indicated he was on the brink of returning, but that’s no longer the case after the injury was aggravated. A re-evaluation is needed, and it appears he may now be in danger of missing the remainder of the season.

Speaking of key injuries, the Mariners finally have most of their elite pitching staff healthy. While Bryce Miller remains on the IL, he is already throwing and should soon start a rehab assignment. With Cal Raleigh and Randy Arozarena both raking at the plate, it seems Seattle is far from out of the AL West race.

The Rangers sit 8.5 games out of the division lead, but still own an impressive +47 run differential. There is no question that this team has the pitching to compete for another World Series run, but the lineup has been bad. The team’s .676 OPS is the sixth-lowest in the league, leading the Rangers’ record to hover around the .500 mark. A couple of trades could help, but we still don’t think it will be enough to win the division in 2025.

MLB AL West Winner - My Pick

Seattle Mariners (+375) at BetMGM Sportsbook

We have been backing the Astros this season, but that has now changed. The setback for Alvarez is a brutal blow, but the rotation is also a critical concern, with Hunter Brown and Framber Valdez carrying the load alone in the first half.

We have always known the Mariners' pitching is elite, but we are starting to fall in love with their lineup. Cal Raleigh continues to be one of the best stories of the season, but we are more intrigued by the recent play of Randy Arozarena. The All-Star seemed like a bust for the Mariners, but finally figured things out in June. That success carried over to July, with the star posting seven home runs and a 1.112 OPS.

As impressive as Houston has been, we believe their injuries make Seattle’s roster the more appealing of the two.
