Mark Buehrle won't be the biggest ticket available at the trading deadline. The White Sox ace agreed to a four-year, $56 million contract with Chicago on Sunday, taking the most attractive pitcher on the rumor mill off the market. The contract essentially includes a no-trade clause through the 2008 season, Buster Olney reports, as Buehrle must consent to any deal. The deal also includes an escalator clause that will make the deal worth $75 million over five years if he is traded before the contract runs out. Buehrle will have 10-5 rights by the 2009 season, meaning he would have to consent before being traded under baseball's collective bargaining agreement.
