Khris Davis homered twice for the second consecutive day, and the Oakland A's banged out five homers for a second straight game Thursday in an 8-5 victory over the host Baltimore Orioles.

Davis, who now has an MLB-leading nine homers this season, became the first Oakland player to have back-to-back multi-homer games since Josh Reddick on Aug. 9-10, 2013.

In Wednesday's 10-3 rout of the Orioles, Davis had two homers and four RBIs. This time, he belted two homers and drove in three runs.

Home runs were the story for the A's throughout this four-game series. Oakland won three games and went deep 14 times to snap out of an early season slump.

The power display helped Aaron Brooks (2-1) earn the victory. He went six innings and gave up three runs on three hits.

Dylan Bundy (0-1) took the loss, again running into home run issues. He allowed an MLB-high 41 homers last year and gave up the first four in this contest, as Oakland scored six runs on seven hits against Bundy in five innings. He struck out eight.

Baltimore's Chris Davis continued to struggle. He flied out in his first at-bat to extend his streak to 58 consecutive hitless plate appearances, dating back to last season. That broke the major league record held by Cleveland's Tony Bernazard since 1984.

Davis went 0-for-3 Thursday and is 0-for-32 for the season.

Dwight Smith gave Baltimore a 1-0 lead in the first with his solo blast off Brooks.

Oakland took a 2-1 lead on Davis' two-run homer in the fourth. Josh Phegley added a two-run shot in the fifth before Davis and Kendrys Morales opened the sixth with back-to-back solo homers for a 6-1 lead.

That ended Bundy's day, and the A's added a run later in the inning before the Orioles rallied in the seventh.

They got one run on a hit batter, another on a wild pitch. The Orioles then used the bats for the final two runs of the inning, the first coming on a Cedric Mullins grounder and the second on Smith's RBI double.

That cut the lead to 7-5, but the Orioles could do no more. Marcus Semien added Oakland's last homer in the ninth, and Blake Treinen closed it for his fourth save.
