PITTSBURGH — Eric Thames was unable to get warm in his hotel room on a cold Saturday night. The next day, his bat heated up on a sunny afternoon.

Thames broke out of his slump with a home run and three hits, sending the Milwaukee Brewers to a 6-2 victory over the Pittsburgh Pirates on Sunday.

“It was just miserable, then to go extra innings on top of it,” Thames said about Milwaukee’s 10-inning loss Saturday night. “I woke up in the middle of the night and I felt under the weather. I was freezing. I had the sleeves on and was under the covers trying to warm up.”

Travis Shaw and Jesus Aguilar also went deep for Milwaukee. Thames connected for a solo shot in the ninth inning off Johnny Barbato, his first homer in 10 games after hitting 11 in his first 20 games.

Signed to a $16 million, three-year contract after playing in South Korea the past three seasons, Thames had gone 4 for 27 in his last seven games. He previously played in the majors with Toronto and Seattle.

“I feel like I’ve been getting pitches to hit but I just haven’t been hitting them. I’ve been fouling them off rather than barreling them,” Thames said. “It’s been a matter of my mechanics more than anything the pitchers have been doing specifically.”

Zach Davies (3-2) won his third straight decision as the Brewers avoided being swept in the three-game series. He allowed two runs and four hits in 5 2/3 innings with seven strikeouts.

Pittsburgh rookie Tyler Glasnow (1-2) pitched a career-high 6 1/3 innings but took the loss. He gave up four runs, three earned, and six hits.

“I thought he pitched a very professional game from start to finish,” manager Clint Hurdle said. “I’m very encouraged by the start.”

Jose Osuna accounted for Pittsburgh’s runs when the rookie hit his first career homer in the sixth. That chased Davies and cut the Brewers’ lead to 3-2.

Thames drove in the game’s first run with a third-inning double. Shaw hit his seventh homer leading off the fourth, and the Brewers scored another run in the fifth on a fielding error by second baseman Phil Gosselin to make it 3-0.

Gregory Polanco had two hits for Pittsburgh.

Pirates center fielder Andrew McCutchen got the day off. He is 3 for 24 in his first six games in May.
