MILWAUKEE (AP) -- Scooter Gennett drove in the go-ahead run with a two-out single in the bottom of the eighth, capping the Milwaukee Brewers' rally from a four-run deficit for a 6-5 win Thursday night over the Washington Nationals.
Gennett's bouncer trickled just inside the third-base bag and into left to drive home Shane Peterson from third. A throwing error by second baseman Anthony Rendon that allowed Peterson to reach two batters earlier proved costly for reliever Aaron Barrett (3-2).
Gennett smiled when he reached first. It was his first game back in the majors since being sent down to Triple-A for 17 games to work on his swing.
Will Smith (2-0) pitched a scoreless top of the eighth -- ending that inning by picking off Bryce Harper -- for the win in his first appearance since returning from a six-game suspension for being caught with foreign substance on his arm.
Francisco Rodriguez tossed a scoreless ninth for his 13th save in as many opportunities.
The Brewers are still in last place in the NL Central, but they've been playing much better of late with five victories in their last seven games.
It didn't look like Milwaukee would pull out a win after a sloppy start Thursday.
Three Washington runs scored on errors, including two runs in a three-run fourth following an atypical throwing miscue by third baseman Aramis Ramirez on a two-out bouncer by Rendon for a 5-1 lead.
But the Brewers chipped away over the middle innings, and Gerardo Parra tied the game at 5 with a solo homer to deep right-center with one out in the seventh off starter Tanner Roark.
Nationals: Ryan Zimmerman was placed on the 15-day disabled list before the game with plantar fasciitis in his left foot, an ailment that affected the first baseman all season. Manager Matt Williams said he thought that Zimmerman would need the minimum time on the disabled list, though for now he needed "total rest" and to get off his feet for a few days.
Brewers: CF Carlos Gomez (sore legs) missed a second straight game. Manager Craig Counsell said he hoped to get Gomez back on Friday or Saturday. ... RF Ryan Braun had two hits and an RBI triple on Thursday, a day after leaving Wednesday's 2-0 loss to Pittsburgh because of dizziness stemming from a left ear ailment.
Nationals: Jordan Zimmerman (5-3) is slated to start Friday back in his home state. The right-hander is 2-0 with a 1.50 ERA in three starts against Milwaukee at Miller Park, which is about 180 miles southeast of Zimmerman's hometown of Auburndale.
Brewers: After a tough start to the season, Mike Fiers (2-6) has been effective over his last six starts. He is 1-2 with a 2.78 ERA in that span.
