Fred Wilpon speaks.......... ]Wilpon puts Piazza in past Hopes his career 'goes on' BY ADAM RUBIN DAILY NEWS SPORTS WRITER Mike Piazza has bat and fate in hands, as pending free agent is unlikely to return. The Mets will show a video tribute to Mike Piazza on Sunday. Principal owner Fred Wilpon offered his own toast yesterday. "He, in my opinion, is going to be the second Met Hall of Famer," Wilpon said at the introductory news conference for the team's new network, SportsNet New York. "... I think he loved being here and was certainly the star of the team. No matter who we had here, I think Mike was always the centerpoint. But things change, which I think is good. I hope Mike goes on and plays out as long as he wants to play out." The Mets and Piazza officially haven't ruled out a return, though it's seemingly a longshot at best - unless both sides exhaust their other options. The catcher will search for AL jobs where he also can serve as DH. And the Mets will search for an alternative so Ramon Castro can remain the backup, with San Diego's Ramon Hernandez and Anaheim's Bengie Molina the most attractive pending free agents. "I like Mike a lot as a person," Wilpon said in rare public comments. "He was a great player here. There's no question. We certainly hope Mike goes on and keeps playing. It remains to be seen where that's going to be. I don't know whether that can be here." Wilpon had kept a low profile this season, declining nearly all interview requests. "One of our players just said to me, 'Where have you been, Freddy?'" Wilpon said. "I've been at every game. I just don't go down to the clubhouse and I'm not on the field. Frankly I like it that way better. We have very good baseball people and it's their job." He didn't want to use the phrase, but yes, Wilpon is happy the Mets played meaningful games in September. "I think it's progress," Wilpon said. "I'm not sure it's success unless you are in the playoffs, and we're not in the playoffs. So that part is a disappointment. I think we made a lot of progress in the entire organization this year. "I think the guys have responded very well. We had times where we were in similar positions in years past and you didn't see the same vibrancy on the field I think you do now." Wilpon committed $172 million to Pedro Martinez and Carlos Beltran last winter. "He's been a great citizen," Wilpon said about Martinez. "He's been a great pitcher. With a little break here and there, he might have won 20 games this year. Everything we've asked him to do, he has done 120%. He's a man of his word. He's a man of character." Regarding Beltran, Wilpon offered: "I certainly have been satisfied with his effort - 110%. He's not satisfied with his performance and he knows he can do better. He knows he will do better. He's a real pro. I mean, he was banged up pretty badly and there was no way he wasn't going to play. I didn't think he was going to play last night because he's got a little tweak in his arm or bicep. ... He's a gamer. It takes time to get adjusted in New York." Wilpon heaped praise on GM Omar Minaya and Willie Randolph. "I think what Omar has done and what Willie has done is they've made it attractive for players to want to play here in New York," he said. "And that was not necessarily always the case. Players are now coming up to Willie and coming up to Omar and they want to be here. And that's exciting."
