This brings up a question I've always wondered about - actually two of them. Why aren't baseball parks standardized like football fields, basketball courts and ice hockey rinks? And why is it a parabola rather than a circular arc, with the distances being the same in all directions?
Why should a player have an easier time hitting a home run on one park than another and why should a player who pulls the ball the ball down the line have an easier time hitting a home run than a hitter who sprays the ball to all fields?
