Now you know who to blame, El Duque

River Avenue Blues reports: 

In an appearance on YES, Brian Cashman said the team offered Pettitte a substantial contract back in December, around $10-12MM. He decided to work out on his own to see how he felt before accepting, but basically told the team to plan on now [sic] having him. Following the Pineda and Kuroda moves, Cashman told Pettitte to stop working out because they didn’t have room for him. Andy kept going and here we are.

So it seems that if Pettitte had said yes when they'd asked him, he'd be nearly $10M richer and the Yankees might still have Jesus Montero.
