On March 1, 1903 — Baseball Rules Committee chairman Tom Loftus of the Washington Senators proclaims that the pitcher’s mound must not be more than 15 inches higher than the baselines or home plate. In 1969, the maximum height will drop to ten inches as the result of last season’s dominating pitching which saw batting averages plummet to all-time lows.
