Bryce Harper missed all of June with bursitis in his left knee and required treatment for the joint earlier this week. Now the situation has worsened further.

According to Mark Zuckerman of CSN Washington Harper is not in the Nationals’ starting lineup for Game 2 of Friday’s day-night doubleheader with the Mets because he aggravated his left knee while diving for a ball in the outfield in Game 1. It wasn’t a serious aggravation but it’s worrisome nonetheless for a Washington team that carries a disappointing 49-54 record into the nightcap at Nationals Park.
