2.3 - Ball Selection
(a) A ball shall be
selected by the referee for use in each match. During the match the
referee may, based on personal discretion or at the request of a player
or team, replace the ball. Balls that are not round or which bounce
erratically shall not be used.
(b) If possible, the
referee and players should agree to an alternate ball, so that in the
event of breakage, the second ball can be put into play immediately.
