Vargas (thigh) is not in the Diamondbacks' starting lineup against the Nationals on Saturday.
Vargas is dealing with a left thigh contusion that forced him to leave Thursday's game against the Dodgers. He entered Friday's game against Washington after being absent from the starting lineup, so Vargas could be available off the bench for the Nationals for Saturday's contest. LuJames Groover will start at first base and bat eighth.
