Are you sure the powers that be will want to change the ball? Owners connect offense to attendance. Chicks love the long ball. Even the change in pitching rules (a reliever must face 3 hitters) is a double intentioned rule...shortens game time and may result in more offense. They're toying with moving the rubber back...why? To improve the pitching advantage? (Which they may be doing unintentionally since pitches that break nastiest are in the last 3 feet.)
