Kaleb Cowart hit a go-ahead grand slam in a six-run sixth inning before adding an RBI triple, and the Angels rallied past the Oakland Athletics 9-7 on Tuesday night.
Oakland dropped five games back of the AL West-leading Astros and 2 1/2 behind the Yankees for the top wild card after Houston and New York each won.
Andrelton Simmons hit a two-run single to get the Angels started in the sixth before Cowart connected against Lou Trivino (8-3) for his club's first grand slam of the season.
With Simmons batting before his hit, the A's challenged that a fan interfered on a potential catch by right fielder Stephen Piscotty in foul territory.
