The Nationals have a chance to even the four-game series against the Braves thanks to the dominant performance from Doug Fister on Saturday. Tanner Roark will take the mound for the Nationals on Sunday and he will be opposed by right-hander Ervin Santana, who has struggled of late. He has a 6.17 ERA over his past seven starts, allowing six home runs and walking 17 batters. The lineups are here. As always, discuss the game below.
