Washington Nationals Bryce Harper, knee problems

WASHINGTON (AP) - Bryce Harper is out of Monday's lineup against the Baltimore Orioles due to bursitis in his left knee.

Nationals manager Davey Johnson says Harper aggravated his sore knee in Sunday's 6-1 win over the Philadelphia Phillies with multiple headfirst slides and by hitting a foul ball off of it.

Team medical director Wiemi Douoguih said the outfielder has inflammation of the bursa sac in front of his knee, which he anticipates clearing up in a couple of days. Harper underwent an MRI which showed some soft tissue swelling, but no structural damage, Douoguih said.

Harper is hitting .287 with 12 home runs and 23 RBIs.

Catcher Wilson Ramos, out since May 16 with a left hamstring injury, will miss another four weeks, Douoguih said.
