The last time Jose Canseco put pen to paper, all of baseball quaked. He promises to do it again - and this time he says he'll have something to say about Alex Rodriguez. Canseco, who wrote "Juiced," his 2005 book detailing his use of steroids with Mark McGwire, Juan Gonzalez, Rafael Palmeiro, Pudge Rodriguez and others, says he has another book in the works, due this fall. He told Boston's WEEI Radio on Friday that he had "other stuff" on A-Rod that will be coming out. When asked directly if Rodriguez had used steroids, Canseco replied: "Wait and see." Rodriguez cut off a question about Canseco's comments yesterday after being asked in Baltimore if he had heard the former slugger's words, saying, "Nope, I haven't. And I have no comment."
