Matt Kemp suffered a setback in his recovery from a hamstring injury. The extent of the setback and how long it will keep Kemp out is not yet known.

Sunday is not good day for hamstrings at Dodger Stadium. Matt Kemp, in his first day back in Los Angeles after rehabbing for a week at Camelback Ranch in Arizona, suffered a setback while running and will not be ready to be activated from the disabled list on Friday, as originally planned.

“We’ve hit a little bit of a snag because he felt just a little something today still. We haven’t quite made a decision on where he’s going next. The running today was to see where he’s at,” manager Don Mattingly said on Sunday. “That tells us today he’s not quite there. Does that mean two days, three days, seven days? I don’t know that answer, but I do know he’s not 100%. Until we get that, then we’ll start thinking about him going out and playing.”

Yet more bad luck in what has been a lost season thus far for The Bison.

Kemp ran and was doing stretching drills with strength and conditioning coach Brandon McDaniel before Sunday’s game with the Braves, all with trainer Sue Falsone, director of medical services Stan Conte, and team physician Dr. Neal ElAttrache. Kemp did work in the outfield and on the bases, and appeared to be in a good mood in the clubhouse, hugging teammates upon his return.

“It’s always good to have Matt around. It would be really nice if he’s out in the field. It’s good to see him back,” Mattingly said. “He looks good, he’s running pretty good. He’s not quite there yet, talking to medical. We’re still not where we need to be.”

Kemp could have potentially returned this Friday from his 15-day DL stint, but they’re now saying he’s looking at a timetable of next week, but that’s contingent on him passing similar tests and going on a rehab assignment.

Carl Crawford had an MRI on his hamstring injury, and swelling was discovered. He’ll miss more than the minimum on his disabled list stay.

As for Crawford, the Dodgers expect him to miss more than the minimum 15 days on the disabled list after an MRI exam on his strained left hamstring revealed swelling.

“That tells us it was fairly significant,” Mattingly said. “It doesn’t sound like two weeks.”

Crawford was placed on the disabled list on Monday, retroactive to June 2. But the Dodgers aren’t sure he will be back this month.

So yeah, that roster crunch everybody is worried about probably isn’t coming soon.

Hanley Ramirez re-injured his hamstring injury late last week and has been out of the lineup since, though he has been pinch-hitting the last handful of games.

The Dodgers are without Hanley Ramirez for a second straight game against the Braves at Dodger Stadium, only Friday night isn’t a scheduled day of rest. Ramirez has tightness in his left hamstring, the same one that landed him on the disabled list for a month with a strain, per Ken Gurnick of MLB.com.

Ken Gurnick reports HanRam also felt stiffness behind his knee, and Don Mattingly fears a DL stint could be necessary, though trainers disagree.

Hanley underwent an MRI Sunday, and the results were probably about as good as can be expected.

“He’s having continued problems enough that they want to get another look at this thing,” said manager Don Mattingly. “We’ll find out if it’s going to be more serious than we’ve been talking about.”

His current status, well before the MRI results are known, is that he hit but can’t run. Mattingly used pitcher Clayton Kershaw to pinch run for Ramirez after he singled in the eighth inning Saturday.

“Guys want to play, but when they can’t run it’s hard to play,” Mattingly said. “Especially with playing short.”

Dodgers will go a man short for the next week, then he’ll aggravate it somehow after pinch hitting and he’ll be put on the DL. Probably.

Josh Beckett has been shut down for four weeks as he attempts to return from nerve irritation and numbness in his right hand and arm.

Dodgers pitcher Josh Beckett will be shut down from throwing for four weeks because of nerve irritation in his right arm and hand, the team announced on Tuesday. Beckett, who saw a nerve specialist in Dallas who confirmed the initial diagnosis, is expected to return to the team on Tuesday.

Manager Don Mattingly said earlier Tuesday that Beckett’s condition wouldn’t require surgery, that rehab would be the route taken by the right-hander. Beckett will continue that rehab on Tuesday.

But with four weeks without throwing, it could be at least two months before he could realistically return to actually pitch for the Dodgers.

The Dodgers and Beckett have chosen rehab over surgery.

Scott Elbert will undergo Tommy John surgery and is done for this year and much of next.

Dodgers relief pitcher Scott Elbert’s 2013 season is over before it ever began. The left-hander needs Tommy John surgery and is out for the season, and with an expected recovery of 12-16 months his 2014 campaign is in question as well.

Elbert was diagnosed with a complete tear of his ulnar collateral ligament after meeting with Dr. Neal ElAttrache and having an MRI exam on Tuesday.

Unfortunately, he just couldn’t stay healthy. Strong non-tender candidate after the season.

Ted Lilly was scratched from his last start due to a “chronic neck disc issue” and hit the DL Sunday.

Dodgers left-hander Ted Lilly will be scratched from Sunday’s start against the Braves because of a chronic neck disc issue. He most likely will be replaced by Triple-A Albuquerque’s Matt Magill, although the club has not made any announcement.

Chronic and neck are never two words you want to hear in tandem.

—–

Scott Van Slyke has been playing with neck and shoulder discomfort … because of course.

Van Slyke has been playing through worsening discomfort that originated from an attempted diving catch of Yadier Molina’s double on May 25. At the time, Van Slyke described the injury as similar to whiplash.

He pinch-ran yesterday, though.

A number of minor-leaguers were placed on and activated from the 7-day DL, with the most notable name being top prospect Corey Seager.

Placed on 7-day DL: RHP Angel Castro, RHP Luis Vasquez, 1B Paul Hoenecke, OF Ryan Mount
Reinstated from DL: RHP Kyle Cofield, RHP Matt Shelton, RHP Sean White, LHP Onelki Garcia, 2B Pedro Guerrero, SS Corey Seager, OF Joey Winker

Seager came back and hit a homer, so everything seems good on that front. The injury won’t be a concern to his long-term prospects.

A couple of top prospects performed well this week in the Dodgers farm system, but the teams aren’t performing that well — especially the Great Lakes Loons. The squad can’t hit, leading to a system-low 14 wins.

Triple-A Albuquerque Isotopes (3-3)

Player Of The Week

Rusty Ryal – 1B

.421/.450/.474/.924, 1 2B, 2 RBI, 2 R, 1 BB, 3 K

Kind of a slow week for Albuquerque hitters, as Ryal hit a lot of singles and not much else. He’s filling in for Scott Van Slyke while he’s busy hitting in the majors.

Pitcher Of The Week

Angel Castro – RHP

13 IP, 8 H, 4 R, 3 ER, 1 BB, 11 K

Castro, 30, isn’t a prospect, but he had a solid week on the hill for the Isotopes. He’s provided some stability for a continuously changing rotation.

—–

Double-A Chattanooga Lookouts (1-5)

Player Of The Week

Yasiel Puig – OF

.360/.448/.680/1.128, 1 HR, 3 2B, 1 3B, 3 RBI, 4 R, 4 SB, 3 BB, 5 K

Puig was mired in a slump before he returned from the disabled list, but he posted a solid week. Puig has a nice .314/.385/.579 triple-slash on the season, and is showing why he was given the largest international contract ever.

Pitcher Of The Week

Rob Rasmussen – LHP

6 IP, 3 H, 2 R, 2 ER, 1 BB, 5 K

Rasmussen is proving to be quite the useful mammal, backing up Zach Lee in the Lookouts’ rotation (not literally). He has a 2.79 ERA, 1.08 WHIP, and an impressive 8.8 K/9 in his first stint in the Southern League.

—–

High-A Rancho Cucamonga Quakes (3-3)

Player Of The Week

Ryan Mount – 3B

.476/.500/.810/1.310, 2 HR, 1 2B, 7 RBI, 4 R, 2 BB, 4 K

Mount continued his hot play with another fantastic week to lead the Quakes. He’s also been moved into the No. 3 spot in the lineup, which should lead to further team success as long he’s hitting well.

Pitcher Of The Week

Garrett Gould – RHP

6 IP, 2 H, 0 R, 1 BB, 8 K

Gould had another good start for the Quakes this week. He began the season miserably but has seemingly gotten on track. He has a 1.42 ERA in his last three starts.

—–

Low-A Great Lakes Loons (1-6)

Player Of The Week

Kevin Taylor – 2B

.318/.400/.545/.945, 1 HR, 2 2B, 2 RBI, 4 R, 2 BB, 6 K

Offense is scarce in Great Lakes, but Taylor has done nothing but hit since joining the club. He has a solid triple slash of .333/.412/.467 in his first 12 games.

Pitcher Of The Week

Carlos Frias – RHP

7 2/3 IP, 8 H, 2 R, 1 ER, 1 BB, 3 K

Frias has helped to pick-up the slack left by some of the young starters (Zachary Bird, Jonathan Martinez, Miguel Sulbaran). The Great Lakes rotation seems to be shaping up, now the team just needs to start hitting.

Pitching was the story for the Dodgers‘ farm system this week, but one positional prospect stood out and was recognized for his great offensive performance.

It’s nice to see youngsters take advantage of their given opportunities.

Triple-A Albuquerque Isotopes (1-6)

Player Of The Week

Matt Angle – OF

.333/.448/.583/1.031, 1 HR, 1 2B, 1 3B, 2 RBI, 5 R, 2 SB, 4 BB, 9 K

Angle, who somehow remained on the 40-man roster for the entire 2012 season, is having a decent 2013 so far. He’s getting consistent playing time with the injury to Alex Castellanos. He, along with others, are going to have to pickup the slack with Tim Federowicz and Scott Van Slyke playing in LA these days.

Pitcher Of The Week

Kelvin De La Cruz – LHP

4 1/3 IP, 4 H, 1 R, 1 ER, 0 BB, 7 K

De La Cruz was an under-the-radar minor-league signing this winter, and so far, he’s pitching well. He’s getting a lot of strikeouts (13.1 K/9) and proving to be a valuable reliever out of the Isotopes’ bullpen.

—–

Double-A Chattanooga Lookouts (4-2)

Player Of The Week

Joc Pederson – OF

.619/.692/.810/1.502, 1 HR, 1 2B, 1 RBI, 3 SB, 5 BB, 2 K

Pederson was somehow not named Southern League Player Of The Week, but he continues to do nothing but hit for Chattanooga. He’s making all kinds of noise and is quickly becoming a more realistic option to be recalled than Yasiel Puig.

Pitcher Of The Week

Ross Stripling – RHP

6 IP, 5 H, 1 R, 1 ER, 1 BB, 8 K

Not bad for a Double-A debut. The 23-year-old was promoted to Chattanooga and was thoroughly impressive. Stripling is proving to be a fast mover and could be some time in LA next year.

—–

High-A Rancho Cucamonga Quakes (3-4)

Player Of The Week

Ryan Mount – 3B

.556/.571/1.074/1.645, 3 HR, 3 2B, 1 3B, 12 RBI, 6 R, 1 BB, 3 K

Mount was named the California League Player Of The Week with an outstanding performance that included a 5-for-5 game. The nearly 27-year-old is this year’s version of C.J. Retherford. Honorable mention goes to Darnell Sweeney, who hit for the cycle in a game this week.

Pitcher Of The Week

Duke Von Schamann – RHP

6 IP, 5 H, 2 R, 2 ER, 1 BB, 5 K

The Quakes’ starter had another good week and is adjusting to the Cal League rather nicely. With Stripling having been promoted to Double-A, Von Schamann is the most consistent starting pitcher the Quakes have remaining.

—–

Low-A Great Lakes Loons (1-5)

Player Of The Week

Kevin Taylor – 2B

.348/.423/.391/.814, 1 2B, 4 RBI, 2 R, 3 BB, 3 K

Taylor got his first action of the season this week and performed well. Too bad he’s about the only Loon who hit even remotely well. Corey Seager is on the disabled list and the “veteran” hitters aren’t hitting right now.

Pitcher Of The Week

Angel Sanchez – RHP

13 IP, 6 H, 3 R, 0 ER, 3 BB, 16 K

It’s disappointing to see Sanchez repeating Low-A, especially at the age of 23, but it’s nice to see he’s pitching well thus far. It’ll be interesting to see if he can continue it, get a call-up to High-A, and try to do better this time around.

The Dodgers continue to spend internationally with the signings of teenagers Michael Medina and Carlos Aquino out of the Dominican Republic, both of whom Chad covered here.

—–

The Dodgers signed three more players to minor-league deals with invitations to Spring Training: Victor Garate, Mario Santiago, and Ryan Mount.

Garate is a former Dodger prospect who is probably best known for being one half of the package the Dodgers sent to the Nationals in exchange for Ronnie Belliard. His acquisition is the most interesting because of his role as a left-handed reliever.

—–

The team also signed right-handed pitcher Kyle Cofield and outfielder Jaylen Harris to minor-league deals.
