Bryce Harper also connected for the Nationals, who reduced their magic number to three. They have a four-game lead over Atlanta with six to play.

Gonzalez (21-8) settled down after a shaky start and lasted six innings, allowing three runs and six hits. He's the first NL lefty to win more than 20 games since Dontrelle Willis won 22 for the Florida Marlins in 2005.

Gonzalez and Mets knuckleballer R.A. Dickey (20-6) are considered the leading candidates for the NL Cy Young Award.
