ATLANTA — Bryce Harper hopes to begin running and hitting next week, and come off the disabled list the first day he is eligible.
But he acknowledged Sunday that his injured left knee had not improved.
Harper was placed on the 15-day DL on Saturday, retroactive to May 27, with bursitis in his left knee.
Harper said, "I feel all right," before adding "It's still swollen and crappy. I'm just trying to get treatment and see if the swelling will go down."
Nationals manager Davey Johnson said Saturday the team would not have placed Harper on the disabled list if the outfielder was close to being ready to play.
Harper said he would have tried to play through the injury in a more critical stage of the season.
"If we're in September, October, I'm going to play," he said. "I wouldn't be sitting down right now. It's one of those things, you've got to be smart about what you do and just try to come in every day and get better."
He is eligible to come off the disabled list June 11, when the Nationals open a series at Colorado.
The knee has bothered Harper since he crashed into the wall May 13 against the Dodgers. He confirmed Sunday that he aggravated the injury with a head-first slide into third base against the Phillies on May 25.
"That's when it got very puffed up, and then it got bad," he said.
SIZEMORE STILL TRYING: Former Indians All-Star CF Grady Sizemore, who hasn't played since 2011 because of a series of injuries, has resumed baseball activities, the Boston Globe reported.

DODGERS: OF Yasiel Puig, one of the team's top prospects, was promoted from Double-A Chattanooga.
