Moyer (9-6) struck out seven, walked two and allowed only two runners past first base.
Alan Mills allowed an infield single to Chad Curtis and walked Chili Davis with one out in the ninth before getting Eduardo Perez to hit into a double play for his first save of the season.
Chuck Finley (13-10) struck out 10, matching his season high, and gave up only two hits in his ninth complete game, tied for tops in the majors. The left-hander walked three, two of which led to the Orioles’ run in the first inning.
