MINNEAPOLIS — The Minnesota Twins have signed newly minted American League Manager of the Year Ron Gardenhire to a two-year contract extension through the 2013 season.

The Twins announced the deal Thursday, the day after the Baseball Writers Associated of America announced Gardenhire was voted as the league’s top manager for the first time in his nine-year career.

The Twins also gave two-year extensions through the 2012 season to Gardenhire’s entire coaching staff. The Twins have won the AL Central six times since he took over in 2002. The Twins went 94-68 this year before being swept in the first round of the playoffs by the New York Yankees.
