PHOENIX -- Just as one Dodgers outfielder leaves Class A Rancho Cucamonga, another is gearing up to take his place.

Matt Kemp went 1-for-3 on Friday in his fourth rehab game for the Quakes before shipping off to Triple-A Albuquerque for games Saturday and Sunday, then moving on to Kansas City for the State Farm Home Run Derby, on Monday at 5 p.m. PT on ESPN.

Andre Ethier will join Rancho Cucamonga next Wednesday and Thursday before both him and Kemp will rejoin the Dodgers to start the second half of the season if all goes well.

Ethier, on the disabled list with an oblique injury, is with the club in Arizona and was not originally going to participate in rehab games.

"I'm glad he's going to play," Dodgers manager Don Mattingly said. "It's not that he necessarily needs to play, though. If he's feeling it, we'd rather know he needs more time than activate him. If we activate him and he feels something, that's 15 more days."

Kemp, still nursing a left hamstring strain, was 6-for-14 in four games for Rancho Cucamonga. He played seven innings in center field on Friday night.

"I think he wanted to maybe step up the competition in the last couple days," Mattingly said of why the outfielder will move his rehab to Triple-A.

Even though he won't participate in the All-Star Game, on Tuesday at 4:30 p.m. PT on FOX, Kemp is scheduled to lead the National League as captain for the Home Run Derby. If anything goes wrong the next three days, though, the Dodgers won't hesitate to pull him out.

"I've talked to Matt, if he feels anything at all, he's going to step out," Mattingly said. "We're not worried about Matt getting hurt at all, though. He has been hitting [batting practice] for over a month. We'd know if something was bothering him. From the beginning, the doctor was never worried about him swinging the bat, it's always been about him running."

Dodgers plan to keep Gordon active after surgery

PHOENIX -- The surgery on Dodgers shortstop Dee Gordon's right thumb Friday went as planned, and manager Don Mattingly hopes the 24-year-old will resume baseball activities in a week.

Gordon tore his ulnar collateral ligament in the thumb on a headfirst slide while stealing third base, his Major League-leading 30th steal of the year, in the eighth inning against the Reds on Wednesday night in Los Angeles. He is expected to miss at least six weeks of action.

"He's doing well, it sounds OK," Mattingly said. "It went pretty much as expected, still same time frame. We definitely needed to do it."

In the early stages of Gordon's rehab, the Dodgers will limit what the shortstop can do, but they plan on keeping him active.

"We'll find some stuff for him to do," Mattingly said. "Once he gets past getting stitches out, he'll take ground balls. He won't be able to throw or hit, but he'll be able to do some stuff that'll keep him strong and make sure things don't go away."

Gordon was hitting .229 with a .280 on-base percentage in 301 at-bats in 78 games.

Worth noting

• Second baseman Mark Ellis, who made his first start since May 18 on Thursday, felt good enough to start again Friday against the D-backs.

The 35-year-old, who suffered a severe leg injury earlier this season, was 2-for-4 on Thursday and scored a run.

• Left-hander Ted Lilly isn't ready to throw off the mound yet but is extending himself on flat ground throwing pitches.

The 36-year-old is currently on the 60-day disabled list with a shoulder injury.

"He's at the point of building arm strength," manager Don Mattingly said. "He's been wanting to get on the mound, but we're not there."

• Lost in the shuffle of all the other injuries the Dodgers have suffered this season, right-hander Rubby De La Rosa is beginning to make significant strides in his return from Tommy John surgery.

The 23-year-old threw two innings in a simulated game Friday in Arizona.

Mattingly said the next plan for him is to get in a regular rotation of pitching every few days. That, too, will likely take place in Arizona.
