Steroids don't give you the eye to see the pitch coming, the brain to decide if it's the one to swing at, or the coordination to actually hit it.
The greatest basketball player in history (and perhaps one of the greatest athletes of all time, period) tried to play pro baseball, and never could manage to hit a breaking ball from AA pitchers.
Steroid-powered musclemen strong enough to pick up Fernando Valenzeula and throw him over the outfield fence wouldn't even have been able to get a bat on one of his pitches.
Congratulations to Barry Bonds.
