HOUSTON (AP) - Chris Carter hit his 32nd homer, a three-run drive in the eighth inning that lifted the Houston Astros over the Oakland Athletics 4-2 on Tuesday night.
Oakland starter Jason Hammel had retired 10 straight batters when he was replaced by Luke Gregerson (3-3) for the eighth inning. Robbie Grossman reached on an error by first baseman Stephen Vogt with one out and Gregerson hit Jose Altuve with a pitch.
Carter then launched a 90 mph fastball onto the tracks atop the wall in left field to put Houston on top.
Josh Fields (4-6) pitched a scoreless eighth for the win and Chad Qualls did the same in the ninth for his 15th save.
The A's began the day tied with the Angels for the AL West lead.
