Garcia is out of the lineup for Wednesday's game against the Mets, Mark Zuckerman of NatsJournal.com reports.
Andres Chaparro will get the nod at first base while the left-handed-hitting Garcia takes a seat against Mets southpaw Zach Thornton. Garcia had started in each of the Nationals' last six games, going 4-for-22 with two doubles and two walks over that stretch.
