In his first and only plate appearance against Samardzija, Harper roped a ball up the first base line that rookie Ryder Jones snagged with a dive toward the foul line. He immediately fell to the ground clutching his knee and had to be helped off the field.
He's fourth in the majors in slugging percentage (.614), fifth in batting average (.326) and OBP (.419) and tied for ninth in home runs (29). Harper remained on the ground for an extended period of time.
A World Series contender might have suffered a serious blow Saturday night.
The start of the game was delayed 3 hours, 1 minute by rain Saturday and there was a light rain in the top of the first inning. And shortly after the game starter, Harper's injury reminded the clubs of the danger of playing in harsh conditions.
With one big league team actually in the stadium, the Nationals finally announced the obvious: Friday's series opener was postponed because of rain, and will be made up as part of a split doubleheader on Sunday.
