Mariano Rivera said Monday that he hopes to pitch again for the Yankees this season. The right-hander has been on the disabled list since May 4 after tearing his right ACL while shagging balls prior to a game against Kansas City. "That's my goal," Rivera said on "The Michael Kay Show" on 98.7 FM ESPNNewYork. "I don't think about it because if it doesn't happen, I will be kind of like disappointed. I take it day by day. I'm working hard and doing what I do. ... That's the way I'm thinking, day by day and positive, definitely. Optimism, positive. Whatever the Lord will allow to happen, will happen." Rivera, though, would not definitely say he will be returning in September for the pennant push. "I don't know," Rivera said. "I can't answer that. I don't know. I want to, I want to be there now, but if there is any chance, only God knows."
