MIAMI -- Bryce Harper left the Washington Nationals' game against Miami on Sunday for precautionary reasons after colliding with Marlins second baseman Derek Dietrich in the first inning.
Harper reached base on a fielder's choice and was attempting to run to third on Jayson Werth's grounder to shortstop Miguel Rojas. Dietrich was going to second to cover the base when the two collided as Rojas' throw went to first base for the final out.
Harper stayed down for several moments, then walked off on his own after trainers tended to him.
Harper is hitting .333 with 36 homers and 85 RBIs. He was replaced by Matt den Dekker.
