On his second final appearance, 21-year-old Alexander – who was defeated by England professional Keith Brewer in the final two years ago – came from 2-0 down to defeat Belgium’s Dave Verey 6-5 including a six-ball clearance in the final frame.
The International team and singles event also included the Channel Islands championships and team inter-insulars.
Organiser Paul Bolton said: ‘It was an exceptionally busy and excellent weekend; the standard gets better every year and for Chris to win the International singles was a fantastic result for him.
‘He’s only a young lad and he won a final which was first class.
Verey’s positional play was brilliant and Chris just edged it in the end.
‘Keith Brewer has won the title for the last four years but he did not come this time so he was unable to defend it.
‘The International team event was the closest ever with six of the seven teams still in the running to qualify for the semi-finals going into the final round-robin matches.
‘I felt really sorry for the Portuguese lads, they lost just one game and therefore narrowly missed out qualifying for the knock-out stages.’
Belgium won the team final against Bristol after beating Jersey A in the semi-final, the latter by winning five frames on the trot after trailing 6-3.
