CINCINNATI (AP) -- Brayan Pena's second career pinch-homer started Cincinnati's big eighth-inning rally and swept the Reds to over the Milwaukee Brewers 8-3 Thursday night.
The Reds hit three homers in all as they pulled within 6 games of the NL Central leaders.
Tucker Barnhart led off the fifth with his first career homer. Todd Frazier added a two-run drive in the sixth off Marco Estrada, who gave up six hits and four walks in six innings.
Pena had homered during a 9-4 loss to the Cubs on Wednesday night. He hit for Bailey with the score tied at 3 in the eighth and connected on the first pitch from Jim Henderson (2-1) for a two-run homer. Cincinnati sent 11 batters to the plate while scoring five times during the inning.
Homer Bailey (2-2) allowed eight hits in a season-high eight innings, finally returning to form after missing much of spring training with a strained groin.
Milwaukee has lost back-to-back games for only the second time this season. The Brewers haven't dropped more than two in a row.
Cincinnati opened the four-game series with another injury. Leadoff hitter Billy Hamilton sprained knuckles on his left hand while making a diving catch in center field and will miss a few games.
Hamilton stretched all out to reach Carlos Gomez's line drive that opened the game. He grimaced and flexed his left hand and wrist as he got up. Chris Heisey hit for him in the bottom of the inning.
Gomez stole a hit from Joey Votto in the bottom of the first, catching his fly at the top of the wall in center. Votto pointed two fingers toward Gomez, who also stole a potential go-ahead homer from him for the final out in Milwaukee's 4-3 win last July 8.
Jean Segura singled in a run in the second, and Gomez doubled home a pair of two-out runs to tie it 3-all in the seventh.
Milwaukee got two players back in the lineup, but outfielder Ryan Braun missed his fifth game because of a strained oblique. Braun is expected back this weekend.
Segura returned at shortstop after being out of the starting lineup for four games because of an injury to his face. Third baseman Aramis Ramirez was back after missing two games with a sore left elbow and went hitless, extending his slump to 0 for 25.
Outfielder Logan Schafer is eligible to return from the disabled list on Saturday, recovered from a strained right hamstring. For now, manager Ron Roenicke is using Mark Reynolds in right field, a position the infielder played during spring training.
