BALTIMORE (AP) Oakland's Khris Davis had another great day. Baltimore's Chris Davis had yet another awful one.
Khris Davis hit a pair of home runs for the second straight game, increasing his major league-leading home run total to nine and leading the Athletics over the Orioles 8-5 Thursday.
''He's hit over 40 home runs a year in a ballpark that's not conducive to hitting home runs,'' Oakland manager Bob Melvin said. ''He's just a great hitter.''
Chris Davis was 0 for 3 with a walk and extended his record hitless streak to 53 at-bats. In the fourth season of a $161 million, seven-year contract, he is 0 for 32 this season and hasn't gotten a hit since Sept. 14, setting the mark for most consecutive hitless at-bats by a non-pitcher.
''I feel like I'm seeing the ball a lot better,'' he said. ''I feel like I'm putting good swings on the ball. I lined out again, drew a walk a little bit later. Just continue to work.''
Josh Phegley, Kendrys Morales and Marcus Semien also homered for the A's, who won three straight after losing the series opener. Oakland hit 16 home runs in the series.
Aaron Brooks (2-1) started against Baltimore for the first time in his career and allowed three runs, three hits and three walks in six innings. Blake Treinen pitched a perfect ninth with a pair of strikeouts for his fourth save.
Dylan Bundy (0-1) gave up six runs and seven hits in five-plus innings with eight strikeouts, and he tied a career-high by allowing four homers. The Orioles have given up at least one home run in all 13 games this season.
''I thought from the stuff-standpoint, it was the best I've seen him all year,'' Orioles manager Brandon Hyde said. ''He kept guys off balance. It was just a few mistakes. They didn't hit singles. They went deep.''
Khris Davis gave Oakland a 2-1 lead with a two-run home run in the fourth, and Phegley boosted the margin to 4-1 with a two-run homer in the sixth. Davis and Morales hit back-to-back home runs in the sixth that ended Bundy's afternoon.
''Guys are putting good ABs back to back,'' Khris Davis said. ''Each guy has taken it upon themselves to follow the guy who preceded them with a good at bat.''
Dwight Smith hit his first home run for the Orioles in the first inning, and Pedro Severino was hit on the helmet by a curveball from J.B. Wendelken with the bases loaded in the seventh. Semien hit a solo homer off Mychal Givens in the ninth.
