Vargas is not in the starting lineup for Saturday's game against the Angels, Spencer Nusbaum of The Washington Post reports.
Vargas will begin Saturday's contest in the dugout after going 0-for-4 with one strikeout in Friday's 3-2 win over the Halos. Jose Tena will make his Nationals debut at third base while Nasim Nunez returns to the lineup at shortstop.
