Harper is in the lineup, playing right field and batting cleanup Tuesday against the Mets, Jamal Collier of MLB.com reports.
As expected, Harper is not missing any time after suffering several nicks in Monday's game including being hit by a foul ball and falling at first base. After homering nine times in the Nats' first 18 games this season, the 23-year-old has cooled off, batting .231 and going yard only six times over 56 games since then.
