MIAMI (AP) — Don Mattingly says he has a four-year deal, but he plans to stay at least 10.

The Miami Marlins have introduced Mattingly as their new manager, the team's seventh since June 2010. Mattingly was hired last week, but the announcement was delayed until after the World Series. He became available when he and the Dodgers parted ways last month.

Mattingly went 446-363 with the Dodgers and won the NL West the past three years, but the team was just 8-11 in the postseason and did not reach the World Series. He goes from a franchise that led the majors with a $290 million payroll last season to a club that ranked last at $64.9.

Mattingly becomes owner Jeffrey Loria's first high-profile managerial hire since Ozzie Guillen four years ago. Guillen was fired after one troubled season, and his four-year contract just came off the books.
