Patience is a trait Ken Williams still is trying to acquire. That's becoming more evident in the case of starting pitcher Mark Buehrle and his future with the White Sox -- a future that likely includes only a handful of starts on the South Side. According to a source close to the situation, negotiations between the Sox and Buehrle's camp have been exhausted, with Williams believing he has no choice but to trade the left-hander, who is the face of the ballclub. The only question now is where? At least seven teams have made serious contact with Williams, with three actually having the resources to pry Buehrle from the White Sox. The Braves and Mets were the leading contenders until this weekend, with the Red Sox now becoming the front-runner.
