Matt Kemp has not played for the Dodgers since July 21 and it does not look like Los Angeles will activate him for a while.
He has not a physical setback as he recovers from an ankle injury, but Kemp has struggled in his rehab assignment.
"He doesn't feel good yet at the plate," manager Don Mattingly told the Los Angeles Times on Sunday, "He's not pushing us to say, 'I want to be there tomorrow.'"
Kemp, playing for Class-A Rancho Cucamonga, is 0-for-11 with five strikeouts. He has hit the ball out of the infield only once in three games.
Rancho Cucamonga is in position to make the playoffs -- the season ends on Monday -- and Mattingly said Kemp might remain with the Quakes or go to the Arizona Instructional League.
When Kemp is activated, there will be a logjam in the Dodgers' outfield with Yasiel Puig, Carl Crawford and Andre Ethier filling in while Kemp has been injured.
Kemp, the NL MVP runner-up in 2011, is batting .263 in 62 games for the Dodgers this season, with five home runs.
