Chaparro isn't in the lineup for Saturday's game against the Marlins, Mark Zuckerman of NatsJournal.com reports.
Chaparro will take a seat Saturday after going 0-for-2 with a pair of walks and two runs scored during Friday's win. While he rests, CJ Abrams will serve as Washington's DH, Abimelec Ortiz will start at first base and Brady House will cover third.
