WASHINGTON - Didi Gregorius drove in the go-ahead run with a bunt single in the 11th inning and Aaron Hill homered as the Arizona Diamondbacks beat the Washington Nationals 3-2 Thursday night to salvage the finale of a three-game series.
Miguel Montero led off the 11th with a ground-rule double off Craig Stammen (4-3). A.J. Pollock ran for Montero and Cody Ross bunted him to third. After Jason Kubel drew a walk, Gregorius bunted down the first-base line. Pollock ran on contact and scored the go-ahead run and Gregorius beat the throw at first.
Josh Collmenter (4-0) pitched the 10th inning and Heath Bell picked up his 14th save as the Diamondbacks snapped a three-game losing streak.
Ian Desmond homered for the Nationals.
Arizona's Patrick Corbin, who came in 9-0, and Stephen Strasburg matched up for seven innings with each allowing two runs.
Strasburg gave up six hits while striking out four and walking two as he threw 113 pitches. It was the first time Strasburg allowed as many as two earned runs in a game since May 4.
Corbin allowed five hits while striking out six and walking two. He threw 111 pitches in what was his fifth straight no decision.
Arizona starting pitchers are 0-7 in 19 starts since Wade Miley won on June 5.
The Diamondbacks trailed 2-0 when Corbin led off the sixth with a single. With one out, Hill, in his third game back from the disabled list, homered off a Strasburg fastball to tie the score. The next two hitters reached base before Strasburg got two fly-ball outs to end the inning.
Washington went ahead in the fourth. Corbin retired the first two Nationals, but walked Adam LaRoche. Desmond then hit a 2-2 breaking ball into the visitors' bullpen for his 13th homer of the year to make it 2-0.
Both pitchers benefited from a sparkling defensive plays.
In the seventh, after Washington pinch hitter Chris Marrero singled and pinch runner Jeff Kobernus stole second, Denard Span hit a shot down the line, but first baseman Paul Goldschmidt made a diving stab and beat Span to first.
Arizona's Jason Kubel made a diving catch in left-center to take an extra-base hit away from Anthony Rendon in the first. In the second, Span made a leaping catch against the center field wall to rob Kubel of extra bases.
