Trea Turner hit a two-run homer with none out in the bottom of the ninth inning as the Washington Nationals overcame blowing a three-run lead and continued their surge with a 6-4 victory over the visiting Chicago White Sox on Wednesday afternoon.

The Nationals won their season-high fourth straight and for the ninth time in 11 games since a four-game sweep to the Mets in New York from May 20-23. They overcame an eighth-inning collapse by their bullpen, which had produced scoreless outings in the previous three games and a 2.70 ERA in the last seven contests.

Turner gave the Nationals their fourth walk-off win when he lifted a 95 mph letter-high fastball off Alex Colome (2-1) into the left field seats. It was Turner's third career walk-off homer and occurred after pinch hitter Brian Dozier drew a four-pitch walk.

Before winning in their last at-bat for the seventh time, the Nationals coughed up a 4-1 lead. Kyle Barraclough gave up Abreu's two-run homer, and Wander Suero allowed a game-tying drive to Welington Castillo. Sean Doolittle (4-1) kept the game tied by striking out Yoan Moncada with two on in the ninth.

The Nationals built the 4-1 lead on two RBIs by Kurt Suzuki, a sacrifice fly by Victor Robles and by capitalizing on a fielding error by Chicago shortstop Tim Anderson.

Suzuki had an RBI single in the second and hit a run-scoring groundout with the bases loaded in the fourth -- two batters after a fielding error by Chicago second baseman Yolmer Sanchez.

After Moncada homered off Anibal Sanchez in the sixth, the Nationals added two runs when Matt Adams scored on Robles' fly ball and Suzuki scored when Anderson misplayed a pop-up by pinch hitter Gerardo Parra.

In his second start off the injured list, Sanchez allowed one run on four hits in 5 1/3 innings. He struck out seven and retired nine in a row before Moncada homered and ended his outing.

Chicago's Dylan Covey allowed two runs on seven hits in five innings.

The White Sox lost for the third time in four games following a season-best five-game winning streak.
