OTM References to Pocket Markers and Rules

Marking the pocket

a. A coaster or some other reasonable marker must be placed next to the shooter’s intended pocket. 

b. Marking the pocket with chalk is not recommended. 

c. Both players may use the same marker. 

d. Only one marker should remain on the table at a time. 

e. If the marker is already at the intended pocket from a previous attempt or game, it is not necessary to touch it, pick it up or reposition it. 

NOTE: Contacting a pocket marker with the 8-ball is not a foul and the shot stands.
