This thread isn't about me, but about a hitter I know. I believe this is happening because the hitter is rolling over and the swing is around the ball, instead of inside and through the ball. This hitter has hit line drives to center or opposite field, but never ever hit a bomb. Quite often the ball leaves the bat with a lot of side spin and dies early. Again I believe the hitter isn't staying inside and through the ball. Instead they hitting around the ball and cutting across it. Thoughts?
