If you were hoping to buy low on Zack Greinke, your time is running out. Set to make a rehab start Friday, he might be just two weeks away from returning, with some reports suggesting he's aiming for even sooner than that.

The initial timteable following surgery to repair his fractured collarbone was eight weeks, but at the time, the Dodgers thought he'd have to rebuild his arm strength. He's been able to continue throwing throughout his recovery.

When healthy, Greinke is a borderline ace, but with only two starts this year and injury concerns dating to spring training, his owner might view him as something of a headache. When he's back on a major-league mound, all bets are off, but right now you might still be able to land him with an Alex Rios or Austin Jackson type.
