OAKLAND, Calif. -- Center fielder Mike Trout hit a solo home run and a two-run double Wednesday night, powering the Los Angeles Angels to a 6-3 victory against the Oakland A's at the O.co Coliseum.

Trout went 2-for-3 with a walk, drove in three runs and scored twice as the Angels evened the three-game series at a win apiece. He homered in the third inning and doubled during the Angels' three-run sixth.

Angels first baseman Albert Pujols, who has 523 career home runs, left the game in the top of the sixth inning because of left hamstring tightness. He started hobbling while running to first on a bloop single and came out of the game for a pinch runner.

Shortstop Marcus Semien went 3-for-4 with two doubles and scored two runs for the A's.

The Angels built a 3-0 lead, gave it all back, then moved ahead 6-3 with three runs in the top of the seventh.

A's right-handed reliever Ryan Cook issued a leadoff walk to left fielder Matt Joyce. Joyce went to third when designated hitter C.J. Cron grounded a hit-and-run single to right. With one out, second baseman Johnny Giavotella grounded an RBI single to center, driving in Joyce to make it 4-3.

Left-hander Fernando Abad walked right fielder Kole Calhoun, the only batter he faced, loading the bases. Abad gave way to right-hander Evan Scribner, who had struck out Trout, Pujols and third baseman David Freese in order in the ninth inning Tuesday night in the A's 6-2 win. This time, Trout drilled a two-run double to left field.

Angels reliever Fernando Salas (1-1) pitched a scoreless seventh and got the win. Cook (0-1) took the loss.

Angels right-handed reliever Joe Smith pitched a perfect eighth inning, and closer Huston Street a perfect ninth for his eighth save in eight chances.

A's right-hander Jesse Hahn returned to the rotation after missing his previous scheduled start with a blister on his right middle finger and got a no-decision. Hahn allowed three runs on four hits over five innings, walked one and struck out a season-high six.

Angels right-hander Matt Shoemaker came off the bereavement list and made his first start since April 20 against the A's but didn't figure in the decision. He gave up three runs on six hits over 5 2/3 innings, striking out three and walking one.

The Angels grabbed a 2-0 lead in the top of the first inning. Calhoun led off with a single to left and moved to second when Hahn walked Trout. Both runners advanced on Pujols' groundout, and second baseman Erick Aybar lined a two-run single to center.

Trout increased the Angels' lead to 3-0 in the third, lining a home run over the left-field fence with two outs. With a 1-0 count, Hahn threw a 90 mph fastball on the inside part of the plate, and Trout crushed it for his fifth home run of the season and second in three games.

Oakland cut the Angels' lead to 3-1 in the fourth as Semien launched a leadoff double off the left-field fence and scored on catcher Stephen Vogt's opposite-field single to left.
