Zack Greinke's best-case scenario to make his first start with the Brewers is now April 16th. "If he's ready at that point, I'm going to be really happy," manager Ron Roenicke said. "I just don't know if he's going to be ready then. I think we're not really planning on that early." Greinke has yet to play catch, but he is doing cardiovascular work. Greinke was injured playing basketball in the offseason.
