Bryce Harper left in pain Saturday.

Nationals right fielder Bryce Harper slipped on the first base bag attempting to beat out a grounder, injuring his left knee in the bottom of the first inning of the game Saturday night against the Giants at Nationals Park. It was still raining when Harper's injury happened.

According to the Washington Post's Jorge Castillo, Harper hurt his knee when he lunged for first base trying to beat out a ground ball. He was carried off the field without putting weight on his left leg.

This latest injury could put a damper on the impressive season and create trouble for the Nationals.

Edwin Jackson (2-2, 3.75 ERA with Washington) of the Nationals was slated to face Chris Stratton (0-2, 6.63 ERA) of the Giants in the pitching matchup Friday. The base may have been slippery following a three-hour rain delay.

For all of the Nationals' injuries this season, and there have been plenty of them, they have been able to avoid anything catastrophic since Eaton tore his anterior cruciate ligament. He played in 105 of Washington's first 113 games.
