PITTSBURGH — Starling Marte hit a two-run home run and Trevor Williams combined with four relievers on a five-hitter as the Pittsburgh Pirates beat the Washington Nationals 2-0 on Wednesday.
Marte homered to center field with two outs in the third off Gio Gonzalez after Jordy Mercer led off the inning with the first of his two doubles. That was enough to give the Pirates just their third win in nine games.
Williams (7-7) won for just the second time in his past 10 starts, giving up four hits with three strikeouts and three walks. He is 2-5 with a 6.26 ERA in that span after going 5-2 with a 2.72 ERA in his first nine outings.
Gonzalez (6-6) remained winless since May 28 despite allowing just two runs, six hits and one walk while striking out four. The left-hander is 0-4 in his past eight starts.
Washington (46-46) lost for the 11th time in 16 games and fell back to .500. The Nationals entered the season as favorites to win a third consecutive NL East title.
Richard Rodriguez, Edgar Santana, Kyle Crick and Felipe Vazquez followed Williams with one scoreless inning each. Vazquez earned his 20th save in 24 opportunities.
Pittsburgh's David Freese had two hits.
NEW BATS FOR BRYCE
A new shipment of bats were in the clubhouse when Nationals CF Bryce Harper arrived at the ballpark, a day after striking out four times in a 5-1 loss on Tuesday.
The bats didn't help much, though, as Harper went 0 for 2 with two walks and a strikeout. His batting average is now .213.
