DENVER -- Disabled Dodgers relievers Kenley Jansen and Hong-Chih Kuo pitched two perfect rehab appearances Saturday night.

Jansen had two strikeouts in two innings for Double-A Chattanooga and could return to the big-league club as early as Monday. Jansen has retired all nine batters he's faced in two rehab appearances, with five strikeouts. He is eligible to be activated Monday after suffering from shoulder bursitis.

Kuo struck out the side in his second rehab appearance this week for Single-A Rancho Cucamonga later Saturday night. He's been out with anxiety disorder and there's no timetable for his return.

Disabled closer Jonathan Broxton threw a bullpen session for the Dodgers in Denver, but manager Don Mattingly said there is no timetable for him to start a rehab assignment.

Meanwhile, the Dodgers removed catcher Hector Gimenez from the 40-man roster and he accepted an outright assignment to Double-A Chattanooga. He made the Dodgers' Opening Day roster, but required knee surgery in April and just completed a rehab assignment.

And veteran infielder Juan Castro, designated for assignment earlier this week, accepted an outright assignment to Triple-A Albuquerque.

Dodgers get Kemp back in starting lineup

DENVER -- Dodgers center fielder Matt Kemp was back in the lineup Saturday night after being a late scratch with a tight left hamstring Friday night.

Kemp was still able to appear as a pinch-hitter Friday night to keep his leading active consecutive-games streak intact at 269, and in the process slugged his 19th home run to trigger a futile five-run rally in the ninth inning of the Dodgers' 6-5 loss to the Rockies.

Kemp took treatment Friday night and Saturday afternoon and was put through agility drills three hours before Saturday's game by trainer Stan Conte. He then took batting practice and shagged flies in the spacious Coors Field outfield.

"I'm better," Kemp said. "I'm going to try."

Manager Don Mattingly said the decision on starting Kemp with a minor injury is a tough one, weighing the cost and benefit of trying to win without him vs. risking a more severe injury that would sideline him longer.

"He's been so hot, so good, that it's really a different lineup if he's out of there," Mattingly said. "There's our two-headed monster with Dre [Andre Ethier]. We don't really have a four-hole guy if he's out of there."

Mattingly batted Casey Blake fourth Friday night, but he went 0-for-3 and couldn't start Saturday night because of a stiff neck.

Mattingly said he couldn't tell Kemp to take it easy to avoid aggravating the injury.

"That's hard to do," he said. "It's wrapped to where he can feel it and that lets you know. It's hard to stop that first movement. A center fielder, with a ball in the gap, he's got to feel comfortable with that. He doesn't necessarily have to be careful, but he has to be honest with us. We can't afford to lose him for two weeks. But it's a tough outfield to play. There's a lot of ground out there."

Stiff neck keeps Blake out of Dodgers' lineup

DENVER -- Dodgers third baseman Casey Blake, who has already been on the disabled list twice this season, was out of the starting lineup again Saturday night with a stiff neck.

"Casey's got a little thing going on with his neck," manager Don Mattingly said. "He's kind of available, but limited. I didn't know about it until last night, but it's been coming on a couple days. It's a pinched nerve. The slow roller last night he really felt it and had trouble turning his head in the [batter's] box."

Blake did not participate in batting or fielding practice before Saturday night's game with the Rockies. He came on as a pinch-hitter for starter Ted Lilly in the sixth inning and delivered a go-ahead bases-clearing double in the Dodgers' 11-7 win.

Mattingly also didn't start struggling infielder Juan Uribe, who is 2-for-17 against Colorado's Saturday night starting pitcher Jason Hammel. In their places, Mattingly started Jamey Carroll at second base and Aaron Miles at third base. Miles had a clutch two-run pinch-single in the Friday night comeback attempt.

"It's a day for Juan to regroup," Mattingly said. "He was looking at film with Manny [Mota] to get back on track. He's been chasing the breaking ball since he came back."

Uribe is hitting .153 with one double in five games since returning from the disabled list with a strained hip flexor muscle. The 37-year-old Blake is hitting .161 on the trip and .196 in 12 games since returning from a month on the disabled list with a staph infection in his left elbow.
