Though X-rays showed no structural damage, Jay was in evident discomfort postgame. Even before he put on the sling, he walked around without extending his right arm. He dug through his locker and put on his shirt only using his left hand.
The Cardinals announced Jay's status as day to day, though the club will likely have a better idea of the severity of the injury, which was classified as a right shoulder sprain, on Friday. If Jay does end up on the disabled list, it would make the first such stint of his career.
Jay sustained the injury in the seventh, as he tracked Drew Stubbs' fly ball to center. He ran awkwardly into the wall as Stubbs' ball cleared the fence. Jay stumbled as he came down and was lifted from the game at the end of the frame.
"I was about to make my jump [at the wall] right there," Jay explained. "I miscalculated my steps."
With Skip Schumaker already set to come off the disabled list on Friday, the Cardinals do have ample outfield depth to be able to carry them for however long it is that Jay will be sidelined. If the club does put Jay on the DL and wants to fill his spot with another outfielder, Adron Chambers would likely be the one. He is the only other outfielder on the 40-man roster who is not already with the big league club.
One move the Cardinals could have made is having Carlos Beltran shift from right field to center. Instead, that center-field position will be assumed by Schumaker, Erik Komatsu or Shane Robinson.
