Mo to go under the knifeBy
Mariano Rivera will have arthroscopic shoulder surgery on Oct. 6, reports Tyler Kepner, to clear up some calcification in his throwing arm. Rivera, who had been throwing with shoulder pain all season, will be ready for Spring Training. My nagging thought: The Yanks doled out very large contracts last year to two players in their late 30s, and both suffered shoulder injuries this year. While Jorge Posada and Rivera both earned their deals and are, in a sense, getting paid for past accomplishments, I can’t imagine the Yanks will give out too many more of these long deals to older players.
