It is time for the Sox to get younger. Ortiz takes up an entire roster spot so that when someone is injured they have to bench them or pay through the pain. At 35 he is likely to have more injuries, as well.
With regret, it's time to say good-bye. Ortiz' reluctance to acknowledge the dysfunctional behavior of some teammates ("it's management's job to make them behave") in a recent interview shows that he's part of the problem. It was a nice run.
