Dave Dombrowski is expressing confidence that Prince Fielder can stay productive through most, if not all, of his expensive nine-year contract. The Tigers signed the 27-year-old to a $214 million deal last month. "The prime of your career is what, through 32, 33?" Dombrowski said. "That's seven of the nine years already, and my gut reaction is that this guy will continue to swing the bat. How his body will look in nine years or seven years, I really don't know. He is a heavy-set guy but he's also become more aware of trying to keep himself in the best shape he possibly can." Fielder and Miguel Cabrera should form a potent middle of the batting order, but the move did create some complications. Detroit is set to shift Cabrera from first base to third to make room for Fielder. "There's very few guys that are Gold Glovers and are batting champions and All-Stars from an offensive perspective. They're called Hall of Famers -- and even some Hall of Famers have had some shortcomings of one area or another," Dombrowski said. "We think Miguel will be adequate at third base from a defensive perspective. I don't mean to say he's going to be a Gold Glover. ... He's got good hands, he's got a strong arm, he wants to play there and he'll work very hard at it."
