118. Establish New Average due to Change in Delivery


If because of injury or disability a bowler finds it necessary to change delivery from right- to left-handed or vice-versa, the league’s board of directors, by majority vote, may permit the bowler to change delivery. If approval is obtained, the bowler must establish a new average.

Commonly Asked Questions – Rule 118e



118e/1
May a bowler switch his/her delivery after the start of the season due to injury?

Yes. However, the bowler is required to obtain permission from the league’s board of directors. If the bowler were later able to return to their original hand delivery, permission would again have to be obtained from the board. No combination of scores bowled both right- and left-handed can be used in computing an average. Therefore, two separate averages would have to be maintained. A bowler who switches without permission forfeits those games.
