Morse will sit for a third straight day Wednesday against the Nationals, Chelsea Janes of the Washington Post reports. Morse has now yielded three straight starts to Justin Bour at first base, which could signify a change. Bour has excelled in a pinch hitting role to begin the season, and it has now earned him some playing time while Morse's .193/.253/.284 start has sent him to the bench. Nobody within the organization has confirmed a swap, but it looks as though Morse's grasp on the position has loosened at the very least.
