Guerrier throws pain-free bullpen session

GLENDALE, Ariz. -- Dodgers reliever Matt Guerrier felt no pain in a Tuesday bullpen session and is confident he will be ready for Opening Day after missing nine days with lower-back pain.

"I felt great," Guerrier said after making 25 pitches. "Nothing's holding me back."

Guerrier is scheduled to face hitters on Friday and pitch in a game on Sunday or Monday.

"I've been optimistic, because every day it's been feeling better," he said. "I really feel better now than when I got here. Actually, I think this has helped, getting some time off, and I can benefit from this."

In other medical news, an MRI confirmed a torn oblique for infielder Ivan De Jesus, who was already a longshot to make the team and now won't be ready for Opening Day.

"He said he feels good," manager Don Mattingly said of De Jesus. "I don't know if that helps getting him on the field any faster. He feels better than the MRI shows. But I've seen enough of obliques to know it takes two to three weeks. It just takes time."

Ethier evoking memories of early 2010

GLENDALE, Ariz. -- If you remember the Andre Ethier who seemed headed for a Triple Crown early in 2010 until breaking his finger, that's what Ethier looks like right now.

Ethier's right knee healed from September surgery. He slugged a two-run homer and drove in three runs Tuesday in the Dodgers' 7-6 win over Milwaukee.

Ethier is hitting .440 with 11 hits -- 10 for extra bases -- for a 1.080 slugging percentage and a 1.563 OPS.

"He's square, creating backspin," said manager Don Mattingly. "He's using the whole field. He looks like himself from a couple years ago."

Ethier, in his free-agent-walk season, was asked if he cared to make any bold predictions like the 50/50 proclamation of home runs and stolen bases by teammate Matt Kemp.

"The number I hope for is more wins than the second-place team," Ethier said. "My goal from Day 1 is to figure out how to help the team win on a daily basis, and at the same time, learn from my teammates and teach them the best we can this year."

Ethier homered off right-hander Marco Estrada after two groundouts against left-hander Chris Narveson.

"It was a mechanical thing. I was over-striding a little and shortened up," he said. "The key more than anything is sound mechanics. Whether it's a righty or lefty, I was out of whack. It was a good sign that I made the adjustment."

Hairston wants more time at short

GLENDALE, Ariz. -- Dodgers utility man Jerry Hairston, who had his second two-error game of the spring at shortstop on Monday, is scheduled to play short in a Minor League game Tuesday.

All four of Hairston's errors came on throws, although one of them could have been charged to first baseman Russell Mitchell for coming off first base too soon.

Nonetheless, manager Don Mattingly indicated a tender arm might have played a part.

"He came in today and said he wanted to play short," said Mattingly. "He feels his arm is feeling better. Early in camp, it wasn't well at all. I don't think he's worried about it. He's played in the big leagues and knows what he needs to get ready. He's telling me he wants more time over there and he'll get it."

Hairston is known for his versatility. He's played more time at second base than anywhere, but also has seen significant time in the outfield, at shortstop and third base. In more than 1,000 Major League innings at shortstop, he has committed only 12 errors.

Guerra, Elbert throw on consecutive days

GLENDALE, Ariz. -- Back-end relievers Javy Guerra and Scott Elbert threw 20 pitches each in a simulated game against Minor League hitters on Tuesday, the day after each pitched in an exhibition game.

Pitching on back to back days for the pair came earlier in this camp than in recent Spring Trainings, but pitching coach Rick Honeycutt said that was more a function of scheduling than to address a concern.

"I don't feel it's that drastically early, although a lot of times it's right at the end and there's no reason for that," said Honeycutt. "Physically, they're stronger and we decided to get it going. Other guys will do it after the off-day [Thursday]."

Guerra and Elbert were roughed up in their Monday outing, while Kenley Jansen, who did not throw Tuesday, pitched a perfect inning Monday.

Guerra's first pitch was taken deep by former Minor League teammate Carlos Santana of the Indians, but Honeycutt said that was mostly a case of poor pitch selection.

"Javy's got a starters mix [of pitches] and sometimes you've got to get the main ones down first," said Honeycutt. "His first pitch was a two-seamer and that's not closer mentality. I don't want my closer to think that way. If he hits my best pitch [four-seamer], I tip my hat to him. If it's my fourth or fifth best pitch, I'm the one who might get shot."

'Flash,' Sheffield visit with Dodgers after win

GLENDALE, Ariz. -- Former Major Leaguers Tom "Flash" Gordon and Gary Sheffield were postgame clubhouse visitors Tuesday, and Dee Gordon and Matt Kemp were glad for it.

The elder Gordon watched son Dee triple, double, single and score two runs in the Dodgers' 7-6 win over Milwaukee.

"If my dad is a good-luck charm, he's a good one to have," said the younger Gordon, who tripled and doubled off left-handed starter Chris Narveson.

Gordon is batting .313 with more walks than strikeouts (4-3).

"I've been trying to tell you guys that for a year now," manager Don Mattingly said when asked if Gordon has the makings of a legitimate hitter. "See the stroke -- he can hit. He's getting a feel for when to take and when not to take. It's part of the process of young players. The reason I've liked Dee all along is the speed, obviously, but the swing is there."

Meanwhile, Sheffield told Kemp he noticed his head moving too much during his swing. Kemp fired up his iPad and they watched his at-bats, and the current Dodgers outfielder agreed with Sheffield's diagnosis.

Kemp had two singles Tuesday but also two strikeouts. He is batting .303 this spring, but has only one extra-base hit (a homer) and seven singles with 10 strikeouts and one walk.

"I'm not really concerned with Matty," said Mattingly. "It's not such a bad thing if you're not where you want to be right now. It's not like he's struggling."
