Mike Piazza is among a handful of players that have been singled out as a steroid user in a new book by Jeff Pearlman, and Tommy Lasorda has rushed to the former catcher's defense. "I don't believe that at all," said Lasorda. "He worked so hard. I saw him in the weight room working out all the time. Whatever (is in the book) is hearsay. I just don't believe it. He comes from a family that's full of good people. "I wouldn't comment on it if I didn't feel strongly about it. He has too much to lose. And he's such a nice young man. He goes to church, he's got a nice family. I know him. I know what kind of man he is and I just don't believe it."
