Dodgers starting pitcher Zack Greinke has been able to resume throwing the last few days, but he is still not sure when he will be able to return to a mound as he continues to recover from elbow inflammation.
Greinke played catch Friday with the team's medical personnel, throwing 63 times between 60 and 90 feet in his first attempt to throw since Monday.
Greinke's next step will likely be a bullpen session, though manager Don Mattingly told MLB.com he is not sure whether Greinke will require a disabled list trip to begin the season.
"Hypothetically, just doing the math, as soon as Zack is ready to go out, we'll get him back in there," Mattingly said.
Mattingly also said he would not be willing to use Greinke in truncated starts in the regular season, stressing that Greinke needs to be 100 percent in order for him to be on the active roster.
Greinke told reporters earlier in the day that he is still holding out hope that he will be ready for the team's opener April 2, but acknowledged he might not be at full strength yet.
