Zack Greinke might take a step back

LOS ANGELES -- Zack Greinke will be pitching Wednesday night, but where?

All indications Friday were that Greinke would be at Dodger Stadium to face the Washington Nationals Wednesday, but Dodgers manager Don Mattingly slowed that train down on Saturday. Greinke might need to make one more minor league rehab start for Class-A Rancho Cucamonga before he's cleared to return, Mattingly said.

"It won't be his decision," Mattingly said. "Sounds like doc's going to have to say he's ready to pitch here. It's not so much that he's ready to pitch here, but that they're willing to take the risk of everything that could happen while he's pitching here."

It's one thing that Greinke can pitch again, one month after breaking his left collarbone. The Dodgers still are concerned that fielding, hitting and running the bases could put his healing bone in harm's way. Greinke has only hit soft toss. It's possible that, when he does return, he'll be under orders to not swing.

"Weird things can happen [when a pitcher bats]," Mattingly said. "He could bunt and run to first, the throw's up the line and the first baseman runs into the guy. Out of the ordinary things could happen."
