Most of the REALLY BIG changes in the MLB rulebook happened before 1900. But of the rule changes after 1900, which do you think has the greatest impact (real or potential) on the selection of annual league batting champion?
Which rule changes have the biggest effect on who wins the batting title?
Some of my nominations:
1. Outlawing of the spitball.
2. The Sac Fly rule (not counting flyout as AB if runner scores after the catch)
3. Using total "plate appearances" rather than "at-bats" to qualify for batting title
4. Changes in the official strike zone
Any thoughts or comments on this?
