Bart (back) remains out of the lineup for Tuesday's contest against the Nationals.
Bart will miss a fourth straight start due to lower-back discomfort. He was said to be available off the bench Monday and should be again Tuesday. The Pirates did not call up a catcher to take the roster spot of the injured Endy Rodriguez (finger), suggesting Bart's return to the lineup is imminent. Henry Davis will start at catcher and bat ninth Tuesday.
