The Astros completed their first sweep of the Red Sox at Fenway in franchise history. The Mariners won (and, honestly, Oakland - complete with 95 wins before September even starts - was "impressive" "enough" to get one from Seattle this series) and the Rangers choked up a lead against the Mets and lost, putting the Astros "tied" with Seattle for 1st, and settling into 3rd place.
AL West:
Seattle (76-57): -
Houston (77-58): -
Euless (75-58): -1.0
Remember that, in the event of a tie between Seattle and Houston, Seattle gets the nod due to head-to-head record.
