Billy keeps a yappin. ] On air, Mets' Wagner continues criticism of Perez BY JIM BAUMBACH | 8:39 PM EDT, May 1, 2008 Billy Wagner expanded on his blunt criticism of Oliver Perez Thursday during his weekly radio spot, saying the Mets will go nowhere this year if the enigmatic lefthander doesn't learn how to battle through his own troubles. In his weekly interview with Michael Kay on 1050 ESPN Radio, Wagner said Perez has to hold himself accountable for lasting only 12/3 innings Wednesday when the team desperately needed length. "You have to be able to look at yourself and say, 'Is that the best I can do?"' he said. Speaking before the Mets' chartered flight to Arizona, Wagner said he and others approached Perez before Wednesday's game and told him they needed length. But what Wagner saw was a pitcher who didn't have his best stuff and didn't fight his way through it. "If he goes out there and battles and comes up short, you know what, we're not going to have a problem with that," he said. "But you have to battle. You have to go out there and find a way." Wagner's statements may not have helped his clubhouse reputation as a talker -- "I'm probably the least favorite guy in the clubhouse," he said -- but he is not worried about any ramifications. He expected Mets manager Willie Randolph to request a private meeting before the flight, and he seemed more than willing to express the same sentiments to him. "I want to win and I know everyone in that clubhouse wants to win," Wagner said, "but sometimes you've got to say something. You might have to stir the pot." As for Perez, Wagner said, "I'll be in the locker room, and if Oliver wants to say something, fine. I love the kid ... If he gets mad at Billy Wagner for saying this and then goes out there and wins ballgames, great. I'm all for it." Wagner said he didn't want to publicly rip his teammate two days in a row, but he did so because he thought it might help Perez become tougher on the mound. "I'm not saying it because I don't like him," he said. "I'm saying it because I expect to be better. "I have no problem with someone coming over and saying they didn't like what I said or why I said it. But when you sit with him and say, 'We need this; we need you to step up right here' and guys are coming to him saying, 'Hey, I see this' and he's not responding, then you know what, if this -- -- you off, if you don't want me to say anything, then go out there and pitch and compete."
