Part of the story on Palmeiro's interview: "I made a mistake," Palmeiro told ESPN's Pedro Gomez on Friday. "I didn't really understand what I was taking and I paid for it. I paid for it very dearly. Life goes on." Palmeiro continues to deny knowingly taking performance enhancing drugs. "I've heard a lot of things out there that are wrong," he said. "People saying I took drugs all my life, I've never touched anything. I worked my butt off my whole career, as a kid, in college, the big leagues, I didn't need anything, I didn't have to cheat at the end of my career, for what? What was I going to gain from it? Whatever I took was tainted, had to have been. There's no other reason unless I got set up. "What I took was a B-12 [vitamin] that was given to me by a teammate. That's it. That was it."
