Chien-Ming Wang pitched six strong innings as the Washington Nationals recorded a 4-1 win over the Atlanta Braves on Saturday at Nationals Park.

The Braves saw their wild-card lead shrink to two games over the St. Louis Cardinals, who rallied for a 2-1 victory on Saturday.

Wang (4-3) allowed four hits and struck out four to defeat the Braves for the first time in his career. He was 0-3 against the Braves in four previous starts.

Drew Storen pitched a scoreless ninth inning to earn his 41st save of the season.

Atlanta's Brandon Beachy (7-3) struck out nine in six innings, but was victimized by a three-run outburst in the fourth that was highlighted by Danny Espinosa's two-run single.

Atlanta received its only run on rookie Freddie Freeman's 21st homer in the fifth.
