Zack Greinke is dealing with an inflamed right elbow, which has cast doubt over whether or not he'll be ready for Opening Day.

Greinke made 63 throws to Stan Conte, vice president of medical services, beginning at 60 feet on Friday.

"It was pretty good," Greinke said. "I don't think anyone was anticipating it not going good. As expected."

Don Mattingly said Greinke would likely get only two more Spring Training starts. The right-hander has pitched only five innings in two spring starts so far.

Mattingly wouldn't say whether Greinke would begin the season on the disabled list.
