Nunez isn't in the lineup for Tuesday's game against the Padres, Mark Zuckerman of NatsJournal.com reports.
Nunez's playing time has begun to dwindle after collecting just three hits in 39 at-bats across his last 15 games. He'll now miss out on the starting nine for the third time in four games while CJ Abrams starts at shortstop and Jorbit Vivas mans second base.
