A right leg issue has Nationals slugger Bryce Harper sitting again Friday night in Philadelphia.
Harper, who was also sidelined Thursday, was originally considered to be dealing only with a cramp.
Manager Matt Williams said Harper's hamstring is feeling better. He also said Harper underwent an MRI, which revealed no major damage, but Harper will take at least one more day of rest before returning to the lineup.
He is enjoying a breakout season with a slash line of .340/.466/.719.
