Believe it or not Tim Raines got the nickname "Rock" before he became addicted to crack/cocaine. The odds of that were about the same as him getting crushed to death by a giant boulder. But, it really just makes it make more sense. Raines was forced to testify in September of 1985 at "The Pittsburgh drug trials," an inquiry into coke usage in baseball. Raines stated that he had a gram of crack in his jersey pocket and that he slid head first to avoid breaking the vial.
