From The New York Times:

... Williams said, he would maintain a waiting game of sorts by staying home, staying in shape, spurning offers of guaranteed contracts from other teams and waiting for the Yankees to change their minds and offer him a guaranteed spot on the roster. He spoke in his usual calm demeanor.

“I think if they wanted me, they would have signed me already,” said Williams, who has spent 16 seasons with the Yankees, the only team he has played for. “The option to go to spring training and see what happened — I don’t think at this moment it is something I want to consider.”
