PITTSBURGH (AP) -- Struggling rookie Orlando Arcia had three hits, including a tiebreaking single in Milwaukee's four-run eighth inning, and the Brewers beat Pittsburgh 7-4 on Saturday night to extend the Pirates' losing streak to five games.

Arcia grounded a bases-loaded single into right field against Felipe Rivero, lifting the Brewers to a 3-2 lead. Pinch hitter Manny Pina followed with a two-run single and Keon Broxton capped the big inning with an RBI single as Milwaukee won its third straight following a six-game losing streak.

Pittsburgh's Neftali Feliz (4-2) was charged with two runs, retiring only one of the three batters before leaving with right arm discomfort.

Arcia, considered the Brewers' top prospect entering the season, raised his batting average to .206 in 29 games since making his major league debut Aug. 1.

Milwaukee slugger Chris Carter had four hits, including a two-run drive off Ivan Nova in the sixth inning for his 31st homer. He had gone hitless in 10 at-bats in his previous three games.

Broxton, a rookie who was acquired from the Pirates in an offseason trade, also had three hits and swiped two bases.

The Pirates rallied for two runs in the eighth inning to cut the deficit to 6-4. Starling Marte hit a 434-foot home run to the batter's eye in center field off Corey Knebel and pinch hitter John Jaso added an RBI single.

But Blaine Boyer got Josh Harrison to hit into an inning-ending double play and Carter added an RBI single in the ninth. Tyler Thornburg got three outs for his eighth save.

The Pirates remained 2 1/2 games behind St. Louis for the second NL wild card. The Cardinals lost 9-1 at Cincinnati.

Carlos Torres (3-3) got the win despite allowing Andrew McCutchen's 19th homer in the seventh inning, tying it at 2.

Marte had three hits and Harrison added two.

Brewers starter Jimmy Nelson allowed only one run in 5 1/3 innings despite six walks. He gave up four hits and struck out four.

Nova surrendered two runs and five hits in six innings with six strikeouts and one walk.
