"I think it had a lot to do with it," Collins said. "But he's also got great stuff.
"He's got a live arm, command of his breaking ball. I was very impressed. He pitched inside when he wanted to. Threw the ball great."
The Miller Park crowd of 38,677 gave Peralta a standing ovation as he walked off after eight. After the game, Peralta drew even greater praise from his teammates.
"I look at his stuff, I don't know how he's not the top prospect in baseball," said Brewers left fielder Ryan Braun. "He's got dominant stuff. There are very few guys who have stuff like that in Major League Baseball."
Peralta set a career high in strikeouts and innings, while the two hits and zero runs allowed also were career bests. With a two-out double in the seventh, Peralta even recorded his first Major League hit.
Mets starter Chris Young may not have been quite as impressive as Peralta on the day, but the veteran right-hander turned in a solid outing of his own. Unfortunately, three big hits -- all home runs -- cost him.
Young served up back-to-back blasts in the fourth to Braun and Aramis Ramirez, and another to Braun in the sixth.
Said Young of the home runs, which came on 2-1, 3-1 and 2-2 pitches: "I fell behind and I didn't hit my spot."
For Braun, the homers were his 39th and 40th of the season, marking his first career 40-home run year.
Braun also reached the career 200-home run mark with his first homer on the day.
"He's one of those guys, he doesn't miss mistakes," Collins said of Braun. "And that's what the great hitters do. When you make a mistake on them, they do big damage. And obviously, you look at his numbers, we're not the only team he hits."
Young went 6 2/3 innings, allowing three runs on eight hits with a pair of strikeouts. The outing was Young's longest since Aug. 21 vs. the Rockies, and 101 pitches marked his highest total since Aug. 14 at Cincinnati.
Making his 18th start of the season, Young has his most in a season since 2008. He also hit 103 innings pitched for the year, eclipsing the 102 1/3 he threw during that '08 campaign.
Has the number of starts this season at all surprised Young coming off a 13-month rehab following major shoulder surgery?
"No. It was my goal," Young said. "I didn't want to come back to get hurt. I worked hard to be where I am. I haven't had a day off. From the time I had the surgery, I've worked hard to be out here. I didn't come back thinking I wouldn't make starts. I've taken care of myself, I've worked hard, and I feel like I'm going to continue to get stronger."
Earlier in the weekend, Collins talked about Young's preparation and how he knows exactly what he has and how to make it work for him. The biggest key is executing pitches and following the game plan, because Young's stuff is not going to overpower anyone.
He made three big mistakes, and the Brewers turned them into three long home runs. But Young's highest praise on the afternoon still came from the same player to put two over the fence.
"He always impresses me," Braun said. "He's always been good. He's one of those guys who is really deceptive. He throws a fastball that's really difficult to get on top of. He's got above-average command, he doesn't walk guys, he rarely gets himself in trouble.
"He certainly threw the ball well today -- we only got a few hits against him, but we were able to make those few hits count."
