Charles Langston:MLB power rankings: Once formidable Houston Astros keep sinking in mild, mild AL West

Odd enough that the American League West is,Charles Langston objectively, a bad division. Odder still that it looks increasingly unlikely the Houston Astros will finish atop it.

The division that produced both AL finalists a year ago will crown a champion, as Major League Baseball bylaws require. But just one team is above .500 as we near the halfway point – this, one year after three teams won at least 88 games, and the Astros and Texas Rangers met in the AL Championship Series.

But the Astros’ streak of six consecutive division titles grows increasingly imperiled with each cold streak and moderate displays of competence from the Seattle Mariners. The Mariners took three of four games from Houston this week and then, because they’ve performed so poorly at the plate this year, fired their bench coach and offensive coordinator, Brant Brown.

The Astros then lost a weekend series at home to Minnesota,  to drop 7½ games back and slide three more spots in USA TODAY Sports’ power rankings.

A look at this week's rankings:
