PITTSBURGH -- Andrew McCutchen could finally crack a smile and have a little fun with the reporters surrounding his locker.

The slumping center fielder had three hits and hard-luck starter A.J. Burnett got his first win of the season on his sixth try as the Pittsburgh Pirates ended their five-game losing streak with a 7-2 victory over the Cincinnati Reds on Thursday night.

McCutchen, who won the National League MVP award in 2013 and finished third in the voting last season, had just his fifth multi-hit game of the season. The center fielder raised his batting average to .210, 86 points below his career mark of .296.

McCutchen answered just "yes" to the first three questions asked after the game, channeling his inner Marshawn Lynch. Finally, McCutchen starting laughing and broke into a grin.

"It feels good to see the work I've been putting in pay off," said McCutchen, who has been playing through soreness in his left knee. "I felt I was close to breaking out the last day or two. If you keep working and keep swinging, eventually the hits will start falling.

Burnett (1-1) went seven innings and allowed two runs and seven hits while walking two and striking out four.

"It's nice to stop the losing streak but the offense was the real stopper in this game," Burnett said.

The 38-year-old right-hander brought a National League-leading 1.45 ERA into the game -- it went up slightly to 1.66 -- but received just five runs of support in his first five starts. He was the first major league pitcher to go winless in his first five starts with an ERA that low since the Chicago Cubs' Ryan Dempster was 0-1 with a 1.02 ERA in 2012.

Burnett, a 17-year veteran, became the 41st pitcher in major league history to strike out 2,400 when he got losing pitcher Anthony DeSclafani swinging in the third inning.

"It's nice and part of it comes from being older," Burnett said. "I'd like to get 2,500, though. I think that'd be a really nice milestone."

Second baseman Neil Walker and catcher Chris Stewart each had two hits for the Pirates (13-15), who had a total of 11 while going 5-for-15 with runners in scoring position. Pittsburgh scored just five runs during its five-game skid and went 2-for-36 with runners in scoring position.

Stewart provided a big hit in the clutch, a two-run single in the seventh inning with the bases loaded and two outs that gave the Pirates a 6-2 cushion. That capped a three-run inning that included a run-scoring single by left fielder Starling Marte, his second RBI of the game.

McCutchen added an RBI single in the eighth.

"This is what we're capable of doing," McCutchen said. "We've got a lot of good hitters in this lineup. We've been able to hold our own without really doing much offensively. We're going to get hot, though, and when we do we're going to get really hot."

DeSclafani (2-3) dropped his third consecutive start. The rookie right-hander gave up three runs in five innings on seven hits and four walks while recording only one strikeout.

"I felt like I put myself in a lot of jams," DeSclafani said. "I definitely wasn't happy with this outing."

Cincinnati third baseman Todd Frazier hit his NL-leading 10th home run. He was one of four Reds with two hits along with right fielder Marlon Byrd, shortstop Kristopher Negron and catcher Brayan Pena.

"I'm happy for Todd on a personal note because he comes to the ballpark with that great attitude every day," Reds manager Bryan Price said of Frazier. "He's comes ready to work, ready to fight, ready to win."

The Reds (14-14), who lost to the Pirates for the first time in six games this season, got within 3-2 in the sixth inning when Byrd hit a leadoff triple and scored on a ground out by first baseman Joey Votto.

The Pirates broke a 1-1 tie with two runs in the fifth inning as Marte hit a sacrifice fly and first baseman Pedro Alvarez followed with an RBI double after Frazier homered in the fourth.

Pittsburgh scored a first-inning run on a single by Walker.
