As a sidelight to his prominent role in changing the game to the power-game, the frequency and popularity of Ruth's home runs eventually led to a rule change pertaining to those hit in sudden-death mode (bottom of the ninth or later inning). Prior to 1931, as soon as the first necessary run to win the game scored, the play was over, and the batter was credited only with the number of bases needed to drive in the winning run. Thus, if the score was 3-2 with the bases loaded in the bottom of the ninth, and the batter smacked an "over the fence home run", the game would end at 4-3, with the batter only allowed a double, and the runners officially stopped on 2nd and 3rd (since they weren't needed to win the game). The new rule allowed the entire play to complete, justified on the grounds that the ball was dead and that all runners could freely advance, thus granting the full allotment of HR and RBI's to the batter, as we know it today. Several players lost home runs that way, including Ruth, whose career total would have been changed to 715 if historians during the 1960s had been successful in pursuing this matter. Major League Baseball elected not to retrofit the records to the modern rules, and Ruth's total stayed at 714.
Another rules change that affected Ruth was the method used by umpires to judge potential home runs when the batted ball left the field near a foul pole. Before 1931, i.e through most of Ruth's most productive years, the umpire called the play based on the ball's final resting place "when last seen". Thus, if a ball went over the fence fair, and curved behind the foul pole, it was ruled foul. Beginning in 1931 and continuing to the present day, the rule was changed to require the umpire to judge based on the point where the ball cleared the fence. Jenkinson's book (p.374-375) lists 78 foul balls near the foul pole in Ruth's career, and the research indicates at least 50 of them were likely to have been home runs under the modern rule.
