Zack Greinke visits Dodgers

LOS ANGELES -- Zack Greinke was back in the Dodgers clubhouse Wednesday, his left arm in a sling three days after he underwent surgery on his left collarbone. Greinke was injured when San Diego outfielder Carlos Quentin charged the mound after being hit by a pitch. Greinke, expected to miss two months, didn't want to comment further on the reason for the confrontation with Quentin.

"I made a mistake one time talking about [Chris] Carpenter and I felt bad about that afterwards," Greinke said. "It's just not anyone else's business, really."

Heading into the 2011 playoffs, Greinke criticized Carpenter for yelling at Milwaukee Brewers hitters and said some Brewers thought the St. Louis Cardinals pitcher had a "phony attitude."

Greinke said he regrets not telling his catcher, A.J. Ellis, about a history of bad blood with Quentin before Thursday's game in San Diego. He had hit Quentin with pitches twice before and Quentin previously had been restrained from charging the mound on one occasion, in 2009 when Quentin played for the Chicago White Sox and Greinke was in Kansas City. After he hit Quentin in San Diego, Ellis did not move to restrain Quentin.

"I should have told him. I knew anyone with the White Sox has always labeled me as someone that does stuff," Greinke said. "I didn't think it would happen, but looking back at it I should have warned him. I know he would feel a lot better about it."

Joining Greinke on the team's disabled list is fellow pitcher Chris Capuano, a day after he strained his left calf covering first base.

Veteran Ted Lilly will take Capuano's place in the Dodgers' rotation, probably coming off the disabled list to make a start on April 24 in New York. The Dodgers entered the season with eight veteran starting pitchers, but are now down to five after they traded Aaron Harang and lost Greinke and Capuano to injury.

The team recalled catcher Tim Federowicz from Triple-A Albuquerque. That will give them the option of using Ellis at designated hitter for their three interleague games in Baltimore this weekend.

Capuano is scheduled to undergo an MRI to determine the severity of the strained muscle. He said he also will receive a platelet-rich plasma injection to try and speed healing.
