1970 World Series was Tainted

I was watching an Orioles classic game, game3 of the 1970 world series against Cincinnati, when the announcer said this, very matter of factly, about Red's pitcher Tony Cloninger:Striken with a mysterious eye ailment in 1967. A reaction from steroids, and uh, he was nearly blind in one eye. His vision's all right now.He threw ball four to the hitter and the announcers found other things to talk about. Not a hint of anything possibly wrong.He was probably roided up for this game. I'm sure they were talking about corticosteroids. But you never know.
