MILWAUKEE (AP) -- Prince Fielder is feeling good at the plate again, and he's got the numbers to prove it.
"They all feel good to me," Fielder said of his homers.
The big first baseman, who led the NL with 50 homers last year, has 16 this year after connecting in the sixth and seventh innings. He also doubled and scored on Hart's 12th homer in the second.
Fielder is batting .341 (47-for-138) with 11 homers in his last 36 games, raising his average from .241 on May 12 to .292. After his latest big game, he said he is feeling better at the plate than he has at any time this season.
"Hopefully, I can keep it up," he said. "When you feel comfortable, good things happen."
Manny Parra (7-2) struggled through five innings but won his fifth consecutive start. He helped himself get out of trouble by inducing three double plays.
"Good thing for the double plays because I was struggling with the strike zone," Parra said. "It was just a bad ol' day, one of those days where I was struggling to find my command."
Parra issued a career-high six of the Orioles' 10 walks, but only one scored. Baltimore went 1-for-12 with runners in scoring position, and left nine runners on base despite hitting into five double plays.
"It's a crazy game," Orioles manager Dave Trembley said. "Things happen and there really isn't any rhyme or reason to it as how it works out. It don't figure."
Garrett Olson (5-3) gave up four runs and four hits in five innings for the Orioles.
"I felt overall I pitched pretty well, I just had a couple of pitches I wish I had back," said Olson, who is 2-3 with a 6.39 ERA on the road and 3-0 with a 3.49 ERA at Camden Yards.
The Brewers have hit 45 home runs in their last 22 games, going 15-7 in that span.
"They got their runs with one swing of the bat, multiple times," Trembley said. "That was the difference in the game."
Baltimore took a 3-2 lead on Kevin Millar's RBI double in the fifth.
Ryan Bukvich, promoted from Triple-A Norfolk before the game, replaced Olson to open the sixth, and Fielder greeted him with a 435-foot home run just inside the right-field foul pole.
Parra allowed three runs and five hits.
"We had a chance early in the game to get Parra out of the game, and we didn't do it," Trembley said. "We had his pitch count way up and had a chance to put a lot more runs on. It didn't happen."
