This is disastrous for the New York Yankees. Derek Jeter's career is all but over, and the Yankees will have to pay him for the next three years. When you consider how much money the Yankees have spent over the years, it's remarkable that they've won only one World Series in the past 10 years. That's easily the least bang for the buck in Major League Baseball.
