After a historic June homer binge, Kyle Schwarber’s July got off to a less promising start. The Washington Nationals slugger exited Friday night’s game against the Los Angeles Dodgers because of an injured right hamstring. Schwarber grimaced rounding first on a single, grabbed the hamstring and immediately left the field. Schwarber was set for an MRI. Schwarber’s mashing from the leadoff spot revived the Nationals’ season in June. He became the third player in major league history to hit 16 homers in 18 games and was chosen NL Player of the Month.
