Jan Verhaas became the first non-Briton to referee the World Championship final when he donned the white gloves at the Crucible Theatre in 2003.
The Dutchman described the world final as "the pinnacle of a referee's career.'' He has now taken charge of five world finals including 2013. Verhaas, whose suave demeanour earned him the nickname 'James Bond' from fans at 2002 China Open, first refereed in local tournaments and pro-ams at a club in Rotterdam.
