||Rafael Cabrera-Bello is disqualified after 11 holes of the second round of the South African Open, having lost all 11 balls in his bag. He was 11 over par for his first 10 holes, with two 6s, an 8 and a 10 on the card.
Although Rule 4-4a allows a golfer to borrow items of equipment (except clubs) from a playing partner or an outside agency, almost all professional tournaments - including the European and Sunshine Tours - are played under the "one ball" rule, meaning that only one type of ball can be played in each round. If a player begins with a Pro V1 he cannot, for example, switch to a Pro V1x.
Cabrera-Bello therefore did rather worse than Roy 'Tin Cup' McAvoy, who managed to hole out at the 18th with his last remaining golf ball.
