The Mets' bullpen has been a mess for most of the season, and Billy Wagner evidently is tired of the pitchers involved shouldering the blame. In a New York magazine article that hits newsstands tomorrow, Wagner points a finger at Willie Randolph and pitching coach Rick Peterson as part of the problem. "We've been throwing four innings a night - for months!" Wagner told the magazine. "Our pitching coach has no experience talking to a bullpen. He can help you mechanically, but he can't tell you emotions. He has no idea what it feels like. And neither does Willie. They're not a lot of help, put it that way."
