So far this year the Astros have handed out 49 losses to American League West opponents. That's not inflating the division's win total.
The AL West, like all divisions, has a cumulative .500 record in intra-division games.
While the AL East had an overall cumulative losing record entering Friday's games, the AL West was 35 games above .500.
But, hey, the Orioles beat the Mariners on Friday.
