Gallo is out of the lineup for Wednesday's game against the Yankees.
Gallo will return to the bench after he had started in three of the Nationals' previous four games while going 2-for-14 with one walk against six strikeouts. In the wake of prospect Dylan Crews' recent call-up from Triple-A Rochester, Gallo no longer appears to have a path to regular playing time in right field and will instead have to settle for part-time work at first base and designated hitter as part of a rotation with Juan Yepez and Andres Chaparro.
