GLENDALE, Ariz. -- Top right-handed prospect Rubby De La Rosa has pitched well enough this spring to earn two more starts, including the final exhibition game, March 30 at Dodger Stadium, manager Don Mattingly said Sunday.

The 22-year-old De La Rosa, who held the champion Giants hitless Friday, is not expected to make the club's Opening Day roster, but Mattingly admits he's coming faster than expected.

"Last spring I never heard Rubby De La Rosa," Mattingly said. "For a guy to hit the radar -- I saw it in L.A. at the development camp and now in live competition -- he makes you open your eyes. All of a sudden he jumps on the radar. It's been quick. You can't really deny what he looks like facing Major League hitters. He could put a smile on your face."

De La Rosa split last year between Class A and Double-A, and was named the organization's Minor League pitcher of the year. The previous year, at rookie ball, he pitched in eight games before being sent home after allegedly having a run-in with a trainer.

Mattingly said the most impressive aspect of De La Rosa is his stuff.

"It's filthy," he said. "He's 97-98 [mph] with a changeup that guys don't see. He has work to do on his breaking ball, but his stuff is legit. You can't teach 98 and the feel he has for the changeup. The breaking ball, at times he doesn't seem to have as good a feel for it."

Mattingly said De La Rosa's progression is now at a critical point.

"He's really still in the spring category where he opens your eyes and you send him down, and he should rip it up and the year could just go bad," he said. "He'll let us know. If he keeps looking like he does now, he'll let us know that he's ready."

Blake gives back a rest, Carroll progressing

GLENDALE, Ariz. -- Casey Blake eased off exercise Sunday to give his sore back a break, showing no signs that he'll be ready for Opening Day.

Blake, who injured his thoracic spine eight days ago, was given a "spa day," according to manager Don Mattingly, with aqua-tred exercises but not baseball action. The previous two days Blake hit off a tee, but conceded that he felt soreness at the end of any torque motion.

"We're just making sure it doesn't go in a different direction," said Mattingly. "He's having a light day today but he's progressing."

Mattingly said he isn't thinking about getting Blake into a game.

"We have to get him into batting practice first, then we'll get him into a game," he said. "We're trying to keep him in shape and not irritate it. He said he feels good until the very end of stuff."

Meanwhile, Jamey Carroll continues to take at-bats in Minor League games while resting his sore right index finger that was hit by a pitch two weeks ago. Carroll is able to hit without pain, but the finger bothers him throwing. He is expected to be active for Opening Day.

Guerrier feels good despite numbers

GLENDALE, Ariz. -- The Dodgers came up with comparatively big money for durable reliever Matt Guerrier because they didn't want to rely on Ronald Belisario again.

So far, though, Guerrier isn't pitching like Guerrier. He was rocked for a pair of homers and four runs in one inning Sunday. In six innings, he's allowed 12 hits, three of them homers, and has an ERA of 9.00.

The initial suspicion is that something must be physically wrong, but Guerrier said that is not the case.

"I go off how I feel and how the ball is coming out of my hand, and right now I feel good," said Guerrier, a six-year veteran signed to a three-year, $12 million deal after establishing his credentials with workhorse efficiency for the Twins. "The results will come. That's what I expect."

The Dodgers, with less than two weeks until Opening Day, are trying not to panic.

"I'm glad it's here. Spring Training is for working things out," said manager Don Mattingly, who noted that White Sox hitters battled Guerrier in the seventh inning. "He's not a guy I worry about."

Guerrier said he's not worried either.

"Last spring I didn't give up a run, and the spring before that was a rough one and I had a good year," he said. "It's one of those things. I hope to get it figured out next time."

Mattingly confident offense in good shape

GLENDALE, Ariz. -- Sunday morning, manager Don Mattingly said the Dodgers would score runs this season, and in the afternoon they did, rallying to beat the White Sox, 9-7.

Nevermind that five of the runs scored on homers by non-roster infielders Corey Smith and Jaime Pedroza, borrowed from Minor League camp. The Dodgers did get a two-run homer from Matt Kemp and two more hits from Andre Ethier. "We're going to be all right," Mattingly said. "We'll score runs. Obviously, we're counting on guys to do what they do. Guys have to have good years. If the guys have solid years, we're going to score runs. I'm really not worried about the offense."

Regardless of Casey Blake's availability, Mattingly said he plans to stick with the framework of the lineup he's been using. Rafael Furcal will lead off, Blake or his replacement would bat second, followed by Ethier, Kemp, James Loney, Juan Uribe, the left-field platoon of Marcus Thames or Jay Gibbons, and catcher Rod Barajas or Dioner Navarro. Against left-handed pitching, Uribe and Loney would probably switch places.

An exception would be on days Tony Gwynn plays left field, because Mattingly said he likes Gwynn in the No. 2 hole.

Relief trio in fine form on Sunday

GLENDALE, Ariz. -- Jonathan Broxton, Hong-Chih Kuo and Mike MacDougal pitched perfect innings of relief Sunday and seem ready for the season to start.

Broxton, the closer coming off a bad second half of last season, will appear on back-to-back days for the first time this spring on Monday.

"I'm happy with where I am," he said. "Now it's time to start fine-tuning it, to zero-in with all my pitches so everything is perfect."

Broxton said his arm strength is improving at his normal spring pace. Pitching coach Rick Honeycutt said Broxton's fastball was clocked at 95 mph in his previous outing but he hadn't checked on this one.

"Power pitchers don't feel at full strength when they get here, or we wouldn't have to be here," Broxton said. It's a process to go through. Even if you feel 100 percent, the [radar] numbers are not there now. Once the lights come on you amp up a little bit."

Kuo won't throw on consecutive days until well into the season, said Honeycutt, to preserve his brittle elbow.

MacDougal, a non-roster invitee virtually assured of a spot on the team, ran his spring scoreless innings streak to 6 1/3 innings by pitching the ninth for his second save. He has allowed three hits.

Good news on Padilla, Garland

GLENDALE, Ariz. -- Injured Dodgers pitchers Vicente Padilla and Jon Garland had upbeat news Sunday in their respective rehabs from injury.

Padilla resumed playing catch Sunday and said he felt better than he did Saturday, when he skipped catch the day after his first bullpen session. Padilla is healing from Feb. 24 surgery to free an entrapped radial nerve in his right forearm.

Meanwhile, Garland said he now is playing catch up to 70 feet with no discomfort from the oblique strain he suffered in a March 9 game. Garland said he didn't know what the next step would be, but he was optimistic that he's making progress without a setback.

Neither pitcher is expected to be ready for Opening Day. Padilla might be ready sooner than Garland because he needs to build arm strength for only an inning or two of relief and not the six or more innings needed by Garland in order to start.
