Ryan Zimmerman singled home the go-ahead run in the seventh inning to lead the Washington Nationals past the San Diego Padres, 5-4, in the middle tilt of a three-game set at Nationals Park.
Bryce Harper had three RBI, Adam LaRoche hit a solo homer and Denard Span went 2-for-3 and with a pair of runs scored for the Nationals, winners in three straight.
Jesus Guzman cracked a three-run homer for the Padres, losers in eight straight.
Nick Vincent (2-1) was pegged with the loss after putting the eventual game- winning run on base in the seventh.
San Diego catcher Yasmani Grandal left the game in the third inning with an apparent right knee injury. Grandal suffered the injury after Nationals second baseman Anthony Rendon slid into his right leg on a play at the plate. Grandal remained on the ground for several minutes before we has carried off the field by the Padres training staff.
The Padres went into the sixth inning trailing 3-1, but Guzman crushed a three-run blast to put the Padres in front. Carlos Quentin and Chase Headley hit back-to-back singles to put two on with one out, chasing Jordan Zimmermann from the game.
Ross Ohlendorf (2-0) came on in relief and promptly served up Guzman's homer, a towering blast to left field.
Washington, though, rallied for a pair of runs in the seventh. Span and Ian Desmond hit back-to-back singles before moving into scoring position on Joe Thatcher's wild pitch. Harper then lifted a sacrifice fly to score Span before Zimmerman ripped a base hit to right field to plate Desmond.
San Diego put two runners on in the ninth with one out, but were unable to cash in on the scoring opportunity. Rafael Soriano got Mark Kotsay to ground out before LaRoche made an incredible diving stab to rob Everth Cabrera of a base hit to end the game. It was Soriano's 24th save of the season.
The Padres finished the game 1-for-14 with runners in scoring position and left six runners on base.
Washington got on the board in the third after Harper worked a bases-loaded walk, and LaRoche's solo shot in the fourth made it 2-0.
Jason Marquis, who started the game for the Padres, helped his own cause with an RBI base hit in the fifth inning.
Harper roped an RBI single to center in the fifth to score Span.
