WASHINGTON -- Ian Desmond's seventh-inning inning broke a tie, and the Washington Nationals came back to beat the Miami Marlins 4-3 Wednesday.
The decisive hit came after Miami reliever Mike Dunn (3-4) issued an intentional walk to hot-hitting Jayson Werth to face Desmond with two outs and runners on first and second.
It was the third hit of the game for Desmond, who also had three hits in Washington's win Tuesday. Desmond is now 13-for-28 (.464) in his past seven games. He leads major league shortstops in with 54 extra-base hits, though his past six hits have been singles.
Werth crushed a long solo homer, his 20th of the year, to center to tie the game at 3 as he led off the sixth against Arquimedes Caminero.
The Marlins took a 3-2 lead in the top of the sixth on an RBI single by Jeff Mathis. Giancarlo Stanton tied the game earlier in the inning with a leadoff homer against Washington reliever Ryan Mattheus, who gave up his first home run of the year in his 24th outing. It was the 17th homer of the year for Stanton and his 12th overall at Nationals Park in just 25 games.
Washington (67-65) won for the eighth time in 11 games. The Marlins fell to 49-82, officially clinching a losing season, though that was most likely sealed when the team began the year 1-9.
Drew Storen (4-2) picked up the win for Washington, which used six pitchers. Tyler Clippard pitched a scoreless eighth, and closer Rafael Soriano threw the ninth for his 35th save.
Mathis golfed a low outside pitch from reliever Craig Stammen over the fence in left to cut the Washington lead to 2-1 in the fifth.
Steve Lombardozzi, getting a rare start at second, had an RBI double in the second to give the Nationals a 1-0 lead before a rain delay.
Washington starter Stephen Strasburg was at the plate with an 0-1 count when the game was delayed by rain in the last of the second.
Strasburg was pulled after the 72-minute rain delay, as manager Davey Johnson had Scott Hairston pinch-hit for Strasburg. Haiston struck out. Stammen came on in the top of the third after Strasburg threw 22 pitches and allowed one walk and no hits in two scoreless innings.
Stammen went three innings and allowed the one run before Anthony Rendon pinch-hit for him in the last of the fifth.
Marlins starter Henderson Alvarez was replaced after the rain delay by Ryan Webb, who gave up an RBI double to Bryce Harper in the third as the Nationals took a 2-0 lead.
