Bryce Harper could come off the disabled list and return to the Nationals' lineup Monday night in the opener of a three-game series at Philadelphia.

"We're still trying to make up our minds," manager Dusty Baker said after Sunday's victory over the New York Mets. "So I will let you know [Monday]."

Harper has been sidelined with a bone bruise in his left knee since slipping on a wet base while running out a grounder Aug. 12. Before getting hurt, the star slugger was batting .326 with 29 home runs and 87 RBIs in 106 games.
