The coaches, managers and physicians may know where Dodgers pitcher Zack Greinke will start Wednesday, but it remained a state secret as of Monday afternoon.

Greinke will either come off the disabled list to start against the Washington Nationals or make another rehabilitation start, likely for Single-A Rancho Cucamonga, with Matt Magill starting for the Dodgers.

"We don't want to wait too long" to announce where Greinke will pitch, Dodgers manager Don Mattingly said. "We just want to make sure everybody's on the same page, getting Ned's input, Doc's input, trainer's input, Zack's putting together what he - if he's going to be able to pitch, what are the things we want him doing, we don't want him doing.

"We just haven't gotten all that together. So we're not ready to say."

Greinke won't pitch for Triple-A Albuquerque because the Isotopes have Wednesday off. Double-A Chattanooga is a long way from Los Angeles, and the Lookouts are playing in Pensacola, Fla. Single-A Rancho Cucamonga is at home Wednesday night.

Mattingly said he didn't know where Greinke's rehab assignment would be if he doesn't pitch for the Dodgers.

Mark Ellis (strained right quadriceps) and Jerry Hairston Jr. (groin) might rehab with Chattanooga later this week, since the Dodgers have a three-game series in Atlanta beginning Friday. Greinke could pitch in Pensacola, then meet the Dodgers the following day in the same time zone. But that seems unlikely.
