Nationals star Bryce Harper was back in the starting lineup for Friday night's matchup against Miami after the outfielder sat out the previous four days with a left thumb injury. Washington began the day two games ahead of the Los Angeles Dodgers for home-field advantage in their upcoming matchup in the Division Series. Nationals manager Dusty Baker has given Harper additional time to heal after the reigning NL MVP jammed his thumb on a slide Sunday at Pittsburgh.
