Ellis set for rehab after testing quad on bases

LOS ANGELES -- Dodgers second baseman Mark Ellis said he expects to begin a rehab assignment Friday with Double-A Chattanooga, and utility man Jerry Hairston won't be far behind.

Ellis tested his strained right quad Tuesday afternoon at Dodger Stadium, running the bases for the first time since he suffered the injury April 26 vs. the Brewers.

"That was definitely the last thing we had to do before I was able to play," said Ellis, who has been taking batting practice, fielding ground balls and throwing for more than a week. "I felt pretty good. It went really well."

Ellis thinks he needs to play at least two rehab games before he's ready to be activated, and manager Don Mattingly agreed.

"Just enough to know that he's going to be able to do it and not feel something," Mattingly said before Tuesday's game against the Nationals.

Hairston, on the disabled list with a left groin strain, has been working out in Arizona at the Dodgers' Spring Training facility at Camelback Ranch-Glendale. He's scheduled to play four innings in the outfield and infield during a simulated game Thursday. If all goes well, Hairston could join Ellis in Chattanooga to begin a rehab assignment.

Lilly, Elbert to make rehab outings at Class A

LOS ANGELES -- Dodgers left-hander Ted Lilly expects to start Wednesday in a Minor League rehab game with Class A Rancho Cucamonga, where reliever Scott Elbert is also scheduled to pitch.

Lilly, on the disabled list with a strained right rib cage, said he will throw about 75 pitches. He threw a bullpen session at Dodger Stadium on Saturday afternoon, and manager Don Mattingly said Monday that the veteran was not experiencing discomfort.

Elbert is working his way back from a pair of elbow operations during the winter. The left-hander began his rehab assignment Friday with the Quakes, tossing a perfect inning and earning the win. He had another 1-2-3 inning Monday, striking out two and throwing 17 pitches. Elbert has not pitched in the Major Leagues since August.

Kemp moves into No. 2 spot for first time since '10

LOS ANGELES -- Dodgers manager Don Mattingly shuffled his lineup for Tuesday's game against the Nationals, with Matt Kemp batting second for the first time since 2010.

Kemp entered Tuesday's game with a 12-game hitting streak. He's batting .320 (16-for-50) during that stretch, with 14 singles and two doubles. Kemp has just one homer and seven doubles in 37 games entering Tuesday.

The Dodgers entered Tuesday's action with 129 runs in 37 games, the second fewest in the National League.

"This is nothing other than trying to just shake our lineup up just a little bit and see if we can put some runs on the board," Mattingly said Tuesday afternoon. "Matt has hit in 12 straight. Even though he hasn't hit for power yet, he's swinging the bat better."

With Kemp in the No. 2 hole behind Carl Crawford, Mattingly believes the center fielder will get better pitches to hit from Nationals starter Dan Haren when Crawford is on base.

"It puts pressure on Haren to throw him strikes if Carl's on base," the manager said. "It's the same thing you're trying to do all the time, match the order."
