But Mattingly added that he was less confident on Monday that Kemp would avoid a return to the disabled list than he was Sunday after Kemp injured the ankle with an awkward slide into home plate in the ninth inning of the Dodgers' 9-2 win in Washington.
Swelling in the ankle remained about the same as Sunday, even though Kemp spent most of Monday in the trainer's room receiving treatment.
Kemp already has spent two stints on the disabled list for shoulder and hamstring issues totaling 35 games and was activated only Sunday, when he hit a home run before suffering the injury when, he said, he didn't run hard from third base because he wasn't expecting a play at the plate.
Yasiel Puig started in center field for the Dodgers Monday night, but Mattingly said Andre Ethier would probably start in center Tuesday and Wednesday nights.
