Athletics win 1st AL West title since 2013

The Oakland Athletics clinched the American League West title by virtue of the Seattle Mariners' 6-1 victory over the Houston Astros on Monday.

It's the A's 17th division title and first since 2013.

At 33-20, Oakland currently owns the third-best record of the three division leaders. The Athletics would host the Astros in a best-of-three first-round series at the Coliseum if the postseason started today.

Houston's loss officially ends its three-year reign atop the AL West. The Astros now hold a 3 1/2-game lead on Seattle for second place in the division.
