SEATTLE (AP) — Khris Davis hit a three-run homer, Paul Blackburn pitched one-run ball into the eighth inning for his first major league victory and the Oakland Athletics beat the slumping Seattle Mariners 7-4 on Thursday night.

Davis' 24th homer propelled a four-run fifth inning that put the Athletics in front 7-0. Marcus Semien, activated off the disabled list Thursday, singled to open the inning, and Yonder Alonso walked. Davis, who struck out in his first two at-bats, then sent a 1-1 pitch over the wall in center to make it 6-0. Bruce Maxwell added a two-out solo homer, his first, to chase starter Sam Gaviglio (3-4).

The only run off Blackburn (1-0) was Mitch Haniger's seventh home run, a solo shot in the fifth. Blackburn allowed eight hits, did not strike out a batter and walked one over 7 2/3 innings in his second consecutive strong start. He gave up one unearned run in six innings without a decision in his debut on Saturday.
