Both are expected to return to Los Angeles on Tuesday, when the Isotopes go on the road. Kemp is expected to be activated from the disabled list for Tuesday night's game, while Rivera likely will require additional games at Class A Rancho Cucamonga before his swing is ready. Both players have been out with strained left hamstrings, but Rivera has been sidelined longer.
"You know it's on the horizon to get guys back," said manager Don Mattingly. "We'll get one, and a couple days after that we'll get another guy back. But it's tough coming back. Jerry [Hairston, who returned Friday night] is back, but you know it takes a couple days to get the rhythm back. It's hard to say Matt will come off and be on fire again."
Kemp's injury snapped his streak of consecutive games played at 399. Mattingly said he expects Kemp to be completely healthy when activated, but he also plans to slip in occasional days off to keep him that way.
"It will probably be easier to give him a break because there's not a streak involved," Mattingly said. "He won't want to come out of the lineup. He doesn't like watching. But it makes it easier to give him a day. I can always pull the manager card."
Disabled third baseman Juan Uribe had his resumption of hitting delayed because of continued soreness in his arthritic left wrist. He's been out since May 14 and is doing everything but hitting.
