Harper (neck) is out of the lineup Sunday against the Giants, Mark Zuckerman of MASN Sports reports.
Harper was an early exit Saturday due to a stick neck, so it's not all that surprising to see the outfielder rested, especially with a team day off on tap for Monday. The Nationals actually find themselves with two days off this week, but will begin a stretch of playing on 20 consecutive days this Friday. Now is as good of a time as ever to rest the team's No. 3 hitter, and until Harper is back, Chris Heisey stands to see extra reps in right field.
