On the road, I liked to be booed, I really did. Because if they boo you on the road, it's either because you're a sorehead or because you're hurting them.
Let the pitcher move first, then, as he draws his arm back, you draw the bat back and you are ready.
If a pitcher sees you fiddling with the bat, he'll stall until your arms are tired before you even get a chance to hit.
Be relaxed and don't wave the bat, don't clench it. Be ready to hit down with the barrel of the bat. Just swing it and let the weight drive the ball.
