Realmuto is not in the lineup for Wednesday's game against the Nationals, Clark Spencer of the Miami Herald reports.
Realmuto will head to the bench for what looks like a routine rest day, with an early-afternoon game on tap following a night game. A.J. Ellis will step in behind the plate. The 26-year-old Realmuto has hit safely in nine of his last 11 games and sits with an even .800 OPS for the season.
