Gio Gonzalez takes the mound for the first time since his name was cleared in the Biogenesis investigation. The Nationals have lost four of the past six games, and are 13 1/2 games behind the Atlanta Braves. Gonzalez (7-4, 3.57 ERA) is coming off one of the worst starts of his career. He is opposed by Julio Teheran (8-5, 3.02 ERA), who has pitched well of late. The lineups are here. As always, discuss the game here.
