Nationals star outfielder Bryce Harper is in the midst of perhaps another National League MVP season. But wet field conditions after a three-hour delay may have derailed that on Saturday night vs. the Giants.

In the bottom of the first inning, Bryce Harper hit a ground ball to first base and sprinted to the bag, racing past starting pitcher Jeff Samardzija. But, when Harper hit first base, his left leg slipped on the bag, causing his knee to shoot straight back. 

Harper flew in the air and appeared to be in agony as he hit the ground while clutching onto the front of his knee. 

Friday's Giants game vs. the Nationals in Washington D.C. was postponed due to weather. Saturday's game was scheduled for 4:05 p.m. PT, but first pitch did not happen until 7:05 p.m. PT due to more inclement weather.

The five-time All-Star is batting .326 with a .419 on-base percentage and .614 slugging percentage to go with his 29 home runs in 106 games played. 

More to come...
