Nicklaus recalled that after winning the British Open at St Andrews in 1970, he walked into the press tent to be told by the American journalist Bob Green: "Jack, that's ten majors, you've got only three more to tie Bobby Jones."
Nicklaus thought to himself: " 'I never counted them and nobody had ever mentioned it before'. And I feel a little sorry for Tiger from that standpoint. They started counting his total before he won one."
