Since the start of 2013, the Nationals have gone 7-18 against the Braves, their foremost divisional rival. If there was ever a time for them to reverse that trend, it would be now. The Braves have lost 10 of 15, and the Nationals have won 12 of 18. Jordan Zimmermann, tonight’s starter, has been the best pitcher in baseball in June, having allowed one run in 25 innings over three starts. Talk about the game right here.
