OAKLAND, Calif. -- After blowing a huge lead and losing Friday night to the Los Angeles Angels, the Oakland Athletics needed a big game from right-hander Jesse Hahn and a bounce-back victory on Saturday.

The A's got both.

Hahn gave up one run in 7 2/3 innings, and the A's defeated the Angels, 4-1, at O.co Coliseum. Hahn (5-5) allowed four hits, struck out four and walked four to improve to 4-1 in his past six starts.

Hahn kept the Angels off balance with a mix of sliders, curves and changeups to go with his best pitch, a low-90s sinker.

"My curveball and my slider really weren't there at the beginning of the year, and I think throwing them more, working on them more in side sessions, I kind of got a feel for them again, and I've been throwing more strikes lately," said Hahn, who gave most of Oakland's depleted bullpen a day off after Friday's 12-7 loss.

"You can't get by with just a fastball. Good hitters, they'll lock into that fastball eventually, so I need to show something else for a strike."

Designated hitter Stephen Vogt went 3-for-3 with an RBI and one of Oakland's five doubles. Shortstop Marcus Semien, right fielder Josh Reddick, third baseman Brett Lawrie and catcher Josh Phegley each hit a double.

The A's scored a run in the first inning and three more in the bottom of the sixth after the Angels had pulled even in the top of the frame.

"Obviously any time you can give Jesse that kind of run support with the way he was throwing, you got to feel pretty good about it," Vogt said. "He looked great out there today, and for the offense to come through for him today is always huge. I'm glad we could do that.

"It's exactly what we needed right there, was our starter to go eight innings. We had great offense last night and again today, so we got to feel good about today's game with the chance to win the series tomorrow."

A's closer Kyle Clippard got the final four outs for his 11th save of the season.

Angels right-hander Jared Weaver (4-8) lost his fourth straight start, matching his career high. He allowed four runs and six hits in 5 2/3 innings, striking out four and walking one.

"Everything was flat," Weaver said. "Command's not there. I was able to keep them off-balance a little bit, but they got to me there in the sixth."

Oakland ended a two-game skid and snapped the Angels' two-game winning streak.

Center fielder Mike Trout went 1-for-2, scored a run and walked twice for the Angels (35-34).

"Obviously, we don't want to be there," Trout said. "We want to be a little better than that. From a team standpoint, it's just putting together wins. Like I said, got to turn the page and win the series. "

The A's took a 1-0 lead in the first inning when Semien ripped a one-out double and Vogt doubled him home for his 51st RBI of the season, which pulled him into a tie at that point with Detroit first baseman Miguel Cabrera for the American League lead.

Hahn escaped jams in the second and third when the Angels put runners on second and third base after he retired the first two batters.

In the second, Hahn struck out third baseman Kyle Kubitza swinging on a 75 mph curve to end the inning. Then in the third, Hahn retired first baseman Albert Pujols on a fly ball to center field.

"He had the ball down all day in the zones," Angels manager Mike Scioscia said. "We had a couple chances early and he got out of it. He pitched into the eighth inning so he pitched a good games for those guys."

The Angels pulled even in the sixth when Trout singled softly to center with one out, Pujols walked on four pitches and shortstop Erick Aybar lined an RBI single.

Hahn got second baseman Johnny Giavotella to ground into an inning-ending double play.

Oakland took control with three runs in the bottom of the sixth.

Vogt led off the inning with a single, and after left fielder Ben Zobrist grounded into a fielder's choice, Reddick brought him home with an opposite-field double down the left field line.

Lawrie lined an RBI double to the alley in left center, making it 3-1 and knocking Weaver out of the game.

Phegley hit right-hander Cam Bedrosian's first pitch down the left field line for a double, bringing Lawrie home. Second baseman Eric Sogard lined a single, but Angels left fielder Efren Navarro threw home to nail Phegley at the plate in a close play.

"To be able to add on a couple late in the game feels like more than a couple at the time, but you certainly have to close it out," A's manager Bob Melvin said. "Clippad came in and did great job for us."

NOTES: Angels 1B Albert Pujols came into Saturday's game with an American League-leading 20 home runs, including nine in June. "I think we're seeing Albert the way he hit during his whole career in St. Louis, and I think it's really exciting," Angels manager Mike Scioscia said. "I think he's healthy. He's swinging the bat as well as he ever has in his life." ... A's backup C Josh Phegley made his 25th start of the season, but No. 1 C Stephen Vogt remained in the lineup, making his second start at designated hitter, after going 2-for-4 with a home run, double and three RBIs Friday night against the Angels. ... Angels LF Efren Navarro, who went 1-for-3 with a double on Friday when he hit leadoff for the first time this season, remained in that spot in the batting order. ... RHP Mike Morin (left oblique strain) will begin a rehab assignment Monday in the Arizona League and then pitch Wednesday for Triple-A Salt Lake. He went on the 15-day disabled list on May 24. ... A's LHP Scott Kazmir will make his eighth career start Sunday against the Angels, one of his three former major-league teams. He is 2-5 with a 7.56 ERA and four straight losses against the Angels.
