Mattingly takes Miami helm

Don Mattingly wants to end to the Miami Marlins' managerial merry-go-round.

"I signed a four-year deal," he said at a Monday media conference in the Florida city. "I plan on being here at least 10."

That would be a big change for the Marlins, who introduced Mattingly as their seventh manager since June 2010. He was hired last week, but the announcement was delayed until after the World Series.
