Brian Cashman is staying with the Yankees. Yesterday, Cashman agreed to a three-year contract extension that keeps him in the Bronx until 2011. And, Cashman will have his work cut out for him, as he needs to rejuvenate an aging lineup and rebuild his starting rotation. On the plus side, he has all the Yankees’ money at his disposal, $75 million in expired contracts, and with the move to the new Stadium the money should pour in. Will Cashman invest it in CC Sabathia and Mark Teixiera? Expect the Yankees to be mentioned as a possible destination for every big free agent, but based on recent history it would be prudent for Cashman to be a selective shopper.
