First, a pitcher's mound is 10.5 inches high, not ten. It used to be higher, but it was lowered in 1969 following the '68 season in the major leagues when several pitchers had dominating seasons, including Bob Gibson's very low ERA and Denny McClain winning 31 gaimes. Also, the winner of the American League's batting title had only a .301 batting average (Carl Yastrzemski).
