Schwarber singled to the right-center field gap and grimaced while rounding first. He made a hard stop as Cody Bellinger cut off the line drive and reached for his right hamstring after he returned to first base.
Manager Dave Martinez and a team trainer came to check on Schwarber, who immediately walked off the field. Schwarber yanked off his batting gloves and threw them as he limped through the dugout.
Martinez told reporters Saturday that Schwarber has a ‘significant’ hamstring strain and will miss extended time.
The Middletown native set a franchise record with 16 homers in June — seven of them leading off a game — as he helped the Nationals turn their season around and climb back into the NL East race. He became the third player in major league history to hit 16 homers in 18 games, and only Sammy Sosa (20 in 1998) has hit more homers in June.
Earlier Friday, Schwarber was named NL Player of the Month.
