DETROIT — Free agent first baseman Prince Fielder and the Detroit Tigers agreed Tuesday on a nine-year, $214 million contract that fills the AL Central champions' need for a power hitter, a person familiar with the deal said.

CBS first reported the agreement.

The person told the Associated Press that the deal was subject to a physical. The person spoke on condition of anonymity because the contract was not yet complete.

Detroit boldly stepped up in the Fielder sweepstakes after the recent knee injury to star Victor Martinez. A week ago, the Tigers announced that the productive designated hitter could miss the entire season after tearing his left ACL.

The Tigers won their division by 15 games before losing in the AL championship series to Texas. Adding Fielder gives the Tigers two of the game's premier sluggers, pairing him with Miguel Cabrera.

The move also keeps Fielder's name in the Tigers' family. His father, Cecil, became a big league star when he returned to the majors from Japan and hit 51 home runs with Detroit in 1990. Cecil played with the Tigers into the 1996 season.
