"I've been sick, and she said, `What's wrong with your voice?"' Lutz said. "She said, `Take your vitamins."'

Lutz wasted no time proving to his mom, Marlen, that he was healthy. The rookie, who was born in the United States and grew up in Germany, hit his first career home run, a three-run drive off the right-field foul pole in the second inning that led Cincinnati over the Milwaukee Brewers 5-1 for a three-game sweep.
Bronson Arroyo (3-4) ended a four-start winless streak, allowing five hits in 6 2/3 scoreless innings with one walk and five strikeouts. He had been 0-3 since beating Philadelphia on April 15, and he snapped out of the slump despite not feeling well, manager Dusty Baker said.
"I'm not sure what he had," Baker said. "Sometimes, you just don't feel right. It's not something you can name. We knew about the seventh that he was about out of gas."
Arroyo rarely feels well in day games, he said.
"I didn't have a whole lot of stuff," he said. "I was grinding from the first inning on. I knew I was getting away with pitches that I normally wouldn't. Luckily, they were beating them into the ground."
Peralta (3-3) gave up four runs -- three earned -- on five hits and two walks in six innings.
Baker got his 1,603rd win as a manager, moving past Hall of Famer Fred Clarke into sole possession of 17th place on baseball's career list, 16 behind Ralph Houk. Baker, in his 20th season as a manager, is 1,603-1,448 (.525).
The Brewers have lost 10 of 12 against Cincinnati. The Reds have won the last four series against Milwaukee in Cincinnati and five of the last six overall.
"It was awesome," Lutz said. "My mom and grandma were watching [on television]. I'm sure they were pretty excited."
He hadn't promised to hit a home run during his pregame Mother's Day phone call.
"I didn't want to get ahead of myself," Lutz said.
Peralta had no problem with the pitch.
"I made a great pitch," he said. "There's nothing I could do. If I had to put it right there again, I would. I don't think he'd hit it."
Cincinnati scored an unearned run in the third. After a throwing error by Peralta on a comebacker, Bruce hit a potential inning-ending, double-play grounder, but shortstop Jean Segura's relay sailed over first baseman Yuniesky Betancourt for another error.
The Brewers have been their own worst enemies, according to manager Ron Roenicke.
"We haven't played well," he said. "We can't do the little things against good teams."
Paul led off the seventh with his second homer of the season, a 404-foot drive into the right-field seats on an 0-2 pitch from Mike Fiers, recalled from the minors Saturday and making his first big league appearance since April 16. Paul has four career pinch-hit homers, including two this season.
