Prince Fielder and the Milwaukee Brewers reached a preliminary agreement Thursday on an $18 million, two-year contract. The agreement is subject to a physical, Brewers' GM Doug Melvin said. Melvin declined to discuss the contract's value. "There's things you have to do to get to that point to finalize deals," Melvin said. "We won't have anything tonight, but there's a good possibility we could have something tomorrow."
