Washington Nationals star Bryce Harper is scheduled to play for the Harrisburg Senators in a rehab start on Saturday in Bowie Maryland. Harper is working his way back to the Nationals after sitting out with a knee injury that has kept him out of the lineup. Harper played with Harrisburg on Thursday and will likely start on Saturday in Bowie. Game time is 6:35pm. The Senators were rained out Friday night in Bowie. They will make up the game as part of a doubleheader on Sunday.
