Brewers right-hander Zack Greinke will pitch for Class A Brevard County on Tuesday. Five days after that, he'll pitch for Class AAA Nashville. Milwaukee manager Ron Roenicke said he thinks Greinke will need three rehab outings, however, before being ready to pitch for the Brewers with a decent pitch count. Greinke has been out since suffering a cracked rib in a basketball game this spring.
