Washington Nationals' Bryce Harper grabs his knee after he was injured running to first during the first inning of the team's baseball game against the San Francisco Giants, Saturday, Aug. 12, 2017, in Washington. The Washington Nationals have had more than their fair share of injuries this season, and yet they've maintained and even extended their lead in the NL East. Star slugger Bryce Harper slipped while trying to beat out an infield hit in the first inning Saturday night, and he immediately collapsed in pain holding his lower left leg.
