Washington Nationals star Kyle Schwarber exited early with a hamstring injury Friday night, and it was uncertain when the streaking slugger would return to the lineup. Schwarber, who hit a franchise-record 16 home runs in June, was removed in the second inning of a 10-5 loss to the Los Angeles Dodgers. Schwarber singled to the right-center field gap and grimaced while rounding first.
