At a busy Ommaroo Hotel at Havre des Pas, the Sarnian never trailed in a brilliant match.
Organiser Paul Bolton said: ‘Jez is the top junior in the Channel Islands and it showed.
It was a brilliant final with excellent potting from both 17-year-olds.
‘We had an entry of 22 this year, that’s about a dozen up on Guernsey last year when most of the players who took part then had travelled from Jersey.
‘Unfortunately we did not finish any of the other competitions last night but we are down to the semi-finals in the ladies and doubles events with two men also through to the semi-finals.
‘There were many very good matches last night with the usual sprinkling of surprises.
Brett Campbell has not played pool for a few years and he has won through to the semi after beating Island snooker player Dave Snell.
‘Ady Bougourd is in the semis too while among the remaining quarter-finalists are holder Chris Melville, former winner Gary Cook, the strongly fancied Aaron Canavan and Guernsey’s sole survivor Mark Hancock.’
Jersey’s Laura Gicquel and Christelle Le Toullic will contest the ladies’ final, Gicquel was runner-up last year while Le Toullic won a last-frame decider to eliminate holder Linda Meddar – a Scottish international cueist.
The tournaments will be completed this weekend during breaks in the CI International taking place at the Ommaroo Hotel.
