The Nationals continue to gain ground in the Wild Card standings as they beat the Mets, 6-3, at Citi Field on Tuesday night. The Nationals are now six games behind the Reds for the second and final National League Wild Card spot. Nationals right-hander Jordan Zimmermann won his NL-leading 17th game of the season, but it wasn’t easy as he lasted only five-plus innings, allowed three runs on eight hits and struck out four batters.
