Historical Notes: After thirty years of Major League action, many unusual incidents had occurred along the basepaths. Among the most unusual was a play in which a baserunner passed a teammate who was running the bases ahead of him. As a result, in 1904, a rule was adopted which stated that a baserunner shall be declared "...out if he touch home base before a baserunner preceding him in the batting order...."
The rule was expanded in 1907 to include a baserunner who passed a preceding runner in a rundown.
