The Houston Astros hold a five-game lead in the AL West at 62-60 while hosting the Mariners at Daikin Park for a three-game series, giving them home-field advantage and stronger overall roster depth. Seattle sits at 57-65 after recent struggles, including a 3-7 stretch, with key bullpen absences such as Matt Brash on the injured list due to a lat strain and additional wrist issues limiting infield options. Probable pitching matchups and the Astros’ recent division form have shaped trader consensus around the home side’s edge, though Mariners road splits and any late lineup adjustments could influence outcomes in the remaining games.
