Mets infielder Jonathan Villar left Game 2 of Monday's doubleheader against the Atlanta Braves with right calf tightness after hitting a double down the right field line in the sixth inning.
Villar grimaced rounding first and then exited the game, as Jose Peraza came in to pinch run for him.
Villar is batting .246 with six home runs and 15 RBI over 183 at-bats in 61 games this season.
