The Nationals sit 8.5 games behind the NL East-leading Atlanta Braves and only half a game ahead of the Philadelphia Phillies. The lone Nationals wins since the all-star break have both come as a result of walk-off home runs. Dan Haren (4-11, 5.79 ERA) takes the mound on Saturday and opposes Dillon Gee (7-7, 4.07 ERA). The lineups are here. As always, discuss the game and other stuff here.
