BALTIMORE -- On the night the Baltimore Orioles honored Earl Weaver, they did a lot of things the late former manager might have liked.

Manny Machado hit a three-run home run, and starter Wei-Yin Chen gave Baltimore six good innings that helped seal a 6-1 victory over the Los Angeles Dodgers and clinched a sweep of Saturday's doubleheader in front of a sell-out crowd of 45,248 at Camden Yards.

Machado went 3 for 4 with a home run, double and four RBI, tying a career high. The 20-year-old's three-run homer in the sixth inning broke the game open for the Orioles (10-7), who have won three straight and four out of five. They also won the first part of the doubleheader by the score of 7-5 earlier in the day.

"It definitely pumps us up, having the crowd behind us and cheering us on definitely helps us," Machado said. "It's no pressure at all. It's just something that motivates us more. Having the crowd behind us, cheering us on definitely helps us go out there and just be ourselves and just play."

The Orioles did a lot of the things that Weaver liked. They got power hitting, turned three double plays and pitched well throughout.

But Machado's bat made the big difference in this game.

Machado came up in the fifth inning with the game tied 1-1. He doubled off Dodgers starter Josh Beckett (0-3) to score Nate McLouth and scored on a double by Adam Jones to give Baltimore a 3-1 lead.

In the sixth inning, Machado's home run ended Beckett's night and put Baltimore up 6-1.

"It went down the middle and that was the difference today," Beckett said. "The pitches that their guys were making were pitches I wasn't, and ultimately that's what lost us the game."

The runs gave Chen some support he hadn't gotten recently. Chen (1-2) had received no runs from Baltimore in his last two starts and also had not picked up a victory in his last 10 starts dating back to Aug. 19.

Chen went six innings Saturday, giving up one earned run on three hits. But he wasn't thrilled with his effort.

"I can tell you the truth. I don't think (about it) that much. I can tell my true feelings," Chen said. "I really thank all my teammates, all the guys behind (who) helped me ... get a win tonight. Our belief tonight is to just go out and get a win tonight."

Tommy Hunter earned the save for the Orioles, pitching the final three innings. The save was the first of his career and helped rest a taxed bullpen.

"I would have signed up for that in blood before we started, to try to get through it. Mac is available tomorrow," Orioles manager Buck Showalter said. "Well, everybody is available with the exception of Tommy. We'll see. That was good."

Baltimore also got some help from leadoff hitter McLouth, who finished 2 for 3 with two runs.

The Dodgers (7-10) have lost six games in a row, their longest losing streak since June 24-30, when they dropped seven straight.

"I'm concerned enough that we have to play better," Dodgers manager Don Mattingly said. "I'm not at the point where I'm not confident in my club. I know we have a good club. It hasn't gone quite the way we wanted it too, but I've got confidence in my club. We just have to put a couple wins on the board."

This is the first doubleheader sweep for the Orioles since Oct. 1, 2010, when they beat Detroit twice in one day. Baltimore will go for the series sweep Sunday afternoon.

Los Angeles jumped in front of Baltimore for the second game in a row when Adrian Gonzalez's sacrifice fly drove in Carl Crawford for a 1-0 lead in the top of the first. Crawford had reached after Chen hit him to begin the game.

The Orioles tied the score on a long home run by Chris Davis in the second. Davis had not homered since April 11, and it was his seventh home run this season. It went an estimated 448 feet, the 11th longest in Camden Yards history.

Baltimore threatened again in the third, loading the bases with two outs. But Beckett got Jones to ground out.

McLouth got the Orioles going again in the fifth when he drew a one-out walk from Beckett. McLouth stole second and reached third on catcher A.J. Ellis' throwing error before scoring on Machado's double for a 2-1 lead.

Two batters later, Jones doubled off the glove of Crawford in left to bring in Machado and put the Orioles up 3-1.
