The A's have made a two-year contract proposal to designated hitter Frank Thomas, according to a team source. The deal could be worth up to $15 million with incentives, which are not a large percentage of the offer. Thomas said a report out of Minnesota that he is looking for a three-year deal is inaccurate; he would accept a two-year offer. Thomas, whose 2006 contract was heavily incentive-laden ($2.6 million of the $3.1 million he'll receive), would not discuss specific dollar figures.
