When is a player considered "in the base path"?

A player is considered "in the base path" when they establish a straight line between the bases without deviating intentionally. This concept is crucial for determining how a player can be deemed obstructed or interfered with during a play. The base path is defined as the area that a runner must take in order to advance from one base to another, which usually involves running in a direct line between the two bases.

The notion of establishing a straight line emphasizes that the player must maintain a pathway that does not fluctuate or change course on purpose. This ensures clarity in play, especially concerning decisions made by fielders who may be attempting to tag the runner or make a play. Following this definition helps umpires and players understand the dynamics of base running and fielding interactions and the implications for obstruction and interference calls.
