Vargas is out of the lineup for Wednesday's game against the Reds.
Though Vargas slugged a solo home run in Tuesday's 5-4 extra-inning loss, he's slashing just .198/.288/.396 with four long balls, 15 runs, nine RBI and one steal in 23 games since the All-Star break. Vargas had started every game since June 22, so manager Will Venable will give the 26-year-old a breather with the hope that the rest day helps ignite his bat over the remaining six and a half weeks of the season.
