PHOENIX — Brewers right-hander Zack Greinke is likely to begin the season on the disabled list because of a fractured right rib he sustained while playing pickup basketball in the offseason.
The former AL Cy Young winner is expected to be out two to four weeks. Initial X-rays were negative, but an MRI exam Monday revealed a hairline fracture in one rib and a bruise in a second.
Greinke, acquired from the Royals in the winter, said he was hurt when he went up for a rebound and fell on his side.
"Everyone always told me not to do it because I was going to get hurt," he said. "It finally caught up to me."
The Brewers open the season March 31 in Cincinnati.
"I'm feeling good but it's not worth it," Greinke said.
