Rule 2 Playing Field
What are the measurement and criteria of a Warning Track?
Response: Rule 2-1d SP and FP
d. Should have a warning track. If a warning track is used, it shall be:
1. An area within the playing field and adjacent to any permanent fences along the outfield and side boundaries.
2. A minimum of 3.65m (12 ft) to a maximum of 4.57m (15 ft) from the outfield and/or side fences.
3. Made of material (dirt, gravel) that is level with, but different from, the playing surface. The material must distinguish itself from the outfield surface, and signal players when they are approaching the fence.
NOTE: There is no requirement for facilities to cut a warning track in the permanent outfield surface (grass or otherwise) when temporary fencing is used (i.e. when a fast pitch game is played on a field designed primarily for slow pitch.)
