Basic physics? Steroids aid in building muscle mass. More muscle with the same weight of bat means you can swing at a great acceleration. AKA, more force. The ball weighs the same, but you put more force into it. More force on a constant mass=faster acceleration, a faster acceleration means a faster velocity, and a faster velocity equals further distance traveled.
As for hand-eye coordination, in the book, they have from various seized federal records that Bonds noted an improvement in his eyesight after taking HGH.
