PHOENIX The Minnesota Twins have shuffled their on-field staff to protect the health of some of their older coaches. I think we all know that we're making the right decision, but that doesn't mean it feels good," Baldelli said. The defending World Series champion Nationals will begin their title defense without Zimmerman and pitcher Joe Ross, who both declined to play because of health concerns. We are one hundred percent supportive of their decision to not play this year, Nationals GM Mike Rizzo said in a statement. Cleveland's 61-year-old manager Terry Francona said he's not nervous, even though he's had previous health issues.
