Vargas went 1-for-3 with a run scored and a stolen base in Wednesday's win over Atlanta.
The 32-year-old utility player began the game on the bench but took over at third base when Nick Senzel fouled a ball off his knee in the second inning. Vargas has posted career-best numbers to begin this season, slashing .298/.383/.404 through 109 plate appearances with four steals, seven RBI and 11 runs. If Senzel misses any time, Vargas would be the next man up at the hot corner.
