Mariano update: Leaning toward surgery

From Peter Abraham:

Just spoke to Mariano Rivera. He has been been pitching with a sore shoulder all season. There is inflammation and calcification. He has been given two options: a series of injections and rehab or surgery. He has not made a decision but seems to be leaning toward the surgery.

It's interested that he's been pitching with a sore shoulder all season. He's had one of his finest years at the age of 38.

If he goes through with the surgery, it's expected to be minor surgery to remove bone chips. Anything involving the shoulder, however, could be cause for concern.
