Sit down. Take a deep breath. And read the bad news on Jorge Posada. The Yanks’ catcher was a very late scratch today because his shoulder tear is not improving, and he will be visiting Dr. James Andrews this week. Posada, who seemed to aggravate his shoulder while throwing out Grady Sizemore yesterday, will end up on the disabled list, and the Yanks now have to pray that Jose Molina can shoulder the load. They have no true backup catcher right now as Chad Moeller has not cleared waivers yet. Doug Mirabelli is a free agent possibility.
