Guerrier active, Wall down, Gordon to 60-day DL.

Right-hander Matt Guerrier was activated from the 60-day disabled list Thursday, ending a DL stay that began on April 19. He’s eligible to pitch tonight after missing 118 games with tendinitis in his right elbow.

In five rehabilitation outings for Single-A Rancho Cucamonga, Guerrier allowed three hits and two runs in five innings. He pitched a scoreless inning Monday for the Quakes. In seven appearances spanning 6 2/3 innings in May, Guerrier allowed two runs.

To make room for Guerrier on the active roster, Josh Wall was optioned to Triple-A Albuquerque. The right hander was 1-0 with an 11.57 ERA in three games.

To make room for Guerrier on the 40-man roster, Dee Gordon was transferred to the 60-day disabled list. Gordon, who hasn’t played since tearing a ligament in his right thumb July 5, will be eligible to return on Sept. 3.

Kemp improving, could be available tonight.

Matt Kemp‘s list of injuries seems to be growing by the day but, remarkably, the center fielder is a possibility to play off the bench tonight against the Arizona Diamondbacks.

Kemp spoke briefly before the game, telling reporters that his knees were still his greatest source of pain. Dodgers manager Don Mattingly seemed to contradict that by saying it was Kemp’s left shoulder, not his knees, that were the slowest to recover from this crash into the center-field wall Tuesday night in Colorado:

Regardless, Kemp rode a stationary bike and ran in the outfield prior to the game, and could make an appearance later on.

“I made the lineup out thinking he might be able to play,” Mattingly said. “I’m sure he can catch a ball. It depends on the situation we’re in.”

“I’m just going to take it day by day,” Kemp said. “I’m trying to get the swelling to go down a little bit.”

More on Chris Reed.

Double-A Chattanooga starter Chris Reed was pulled after two innings Tuesday because his strict innings limit is becoming even more strict as his first full professional season draws to a close.

The left-hander was the closer at Stanford University a year ago and is slowly being converted to a starter in the Dodgers’ system. In his only three appearances last season at Single-A Rancho Cucamonga,all starts,Reed pitched a total of 7 innings.

In Double-A, Reed has never gone beyond four innings. He’s pitched four innings twice, three innings six times, and less than three innings three times. Yesterday’s outing was predetermined to last two innings. That’s no guarantee that Reed isn’t being talked about as trade bait –a possibility addressed here last night and something the Dodgers have been known to do lately — only that he was not pulled because of a potential trade.

Reed was the Dodgers’ first-round draft pick, 16th overall, in 2011. He is 0-3 with a 4.41 ERA in 32 2/3 innings (spanning 11 appearances and 10 starts) at Chattanooga this season.

On a personal note, I’m off to scout wedding locations for a couple days. The Dodgers and I return home Thursday.
