Zack Greinke is expected to begin the season on the disabled list after suffering a hairline fracture in one of his ribs playing pickup basketball. The Brewers acquired Greinke in a trade with the Royals this offseason. The team previously had said that Greinke suffered an injury a couple of weeks ago during an off-the-field activity, but the right-hander didn't receive the diagnosis of a broken rib until Tuesday. "Everyone always told me not to do it because I was going to get hurt," Greinke said. "It finally caught up to me."
