Cardinals closer Jason Isringhausen received a cortisone shot for his ailing hip on Monday, and St. Louis said he won't be used until the weekend. Isringhausen has not pitched since Wednesday, when he blew his career-high 10th save in 43 chances. After giving up two runs in the ninth inning of a 7-6 loss at Washington, he said the hip had been bothering him. "I'm really not doing anything until later this week," Isringhausen said. "I don't know what's going to happen."
