Next step for Greinke is facing batters

GLENDALE, Ariz. -- Dodgers pitcher Zack Greinke is scheduled to throw to hitters on Saturday. He threw a 25-pitch bullpen session on Thursday.

"I know he's getting on the mound, and it makes me happy," Dodgers manager Don Mattingly said. "It's the start of the process. I would think he would be in the 30 [pitches] range. It's kind of like his first outing."

Greinke, who injured his right calf four pitches into his first start of spring, is not expected to make the Dodgers' season-opening trip to Australia. He is on track to pitch in a Spring Training game next week.

Guerrero adjusting to life in US, at second base

GLENDALE, Ariz. -- Dodgers infielder Alex Guerrero is still adjusting to life in the United States, but the longtime shortstop said he is starting to feel more comfortable in his new surroundings, which includes his new position at second base.

"I've never played the position before. The ball comes at a different angle, the footwork is different -- especially turning double plays -- but I've worked really hard the last six weeks," said Guerrero, who defected from Cuba last year. "It's been more than a year since I played in games in Cuba. Yes, I worked out, but you can't duplicate the rhythm of a game, especially at this level. I'm finding that rhythm now. You lose that type of thing when you don't play every day."

Guerrero was 5-for-17 with six RBIs in his first seven games of Spring Training. He had one extra-base hit -- a grand slam -- and four strikeouts.

"The pitching is much better here than in Cuba," he said. "The pitchers hit the corners, inside and outside, and it's at a much higher velocity. Every pitcher is good here, but I'm adjusting to it."

It remains unclear if Guerrero will break camp with the Major League team or start the season in the Minors. The Dodgers might use some combination of players from a group that includes Dee Gordon, Justin Turner and Chone Figgins at second base if Guerrero does not make the team.

"I hope I make the big league team and I'm working hard for that, but if they decide I have to go to the Minor Leagues, I will go and keep working hard," he said. "That's what I'm here to do."

The club has not named a starter at the position.

"I don't think now is the time to talk about where [Guerrero] is going to end up," Dodgers manager Don Mattingly said. "Now, we are still competing for a job. We are going to let him continue to play, and again, the plan for him is to get as many at-bats as possible while we are getting other guys ready also and giving them opportunities. At this point, we are happy with Alex and the way he is working and going about his business."

Mattingly discusses collisions, replay with team

GLENDALE, Ariz. -- Dodgers manager Don Mattingly and his staff discussed the new guidelines for home-plate collisions and extended instant replay in a private meeting with his players on Friday morning.

On Thursday, the Dodgers were involved in their first replay review of the Cactus League season against the Angels when Angels outfielder Mike Trout was called out at the plate. Angels manager Mike Scioscia said he challenged the call on the tag and a perceived blocking of the plate.

The call was reviewed and upheld.

"I think everybody will be patient with it, for the most part," Mattingly said. "I think the play at the plate is going to be the most confusing. It's the toughest one to call."

Rule 7.13 states that catchers are not allowed to block home plate without the ball in hand. It also says that runners must not deviate from their path to the plate in order to initiate contact with the catcher.
