Mets closer Francisco Rodriguez has been released from the hospital following severe back spasms on Saturday night. New York manager Jerry Manuel was unsure of when Rodriguez will be able to pitch again. "They gave me some medicine and it feels better," Rodriguez said, adding that he might have been able to pitch on Sunday. "He's still managing it. It feels much better today," Manuel said. "His availability is still undetermined at this point. I have to check to see if he has a history of this thing. I haven't found that out yet."
