Now, Royal Jersey team captain Dan Burchell can turn his attention to finals day at the back end of September at Rowlands Castle, after winning the last three matches to win 4-3.
“I think it was a bit of a surprise for L’Ancresse on home soil,” said Burchell.
“They were very confident going into the match, but we showed a lot of fight and character from a tough position, especially on an away course.”
L’Ancresse got off to a winning start when Tom Le Huray edged past Kevin Therin on the first play-off hole, after the duo were locked after 18 holes.
But the visitors drew level after 13-year-old Aiden Wilson ground out an impressive 2&1 victory over L’Ancresse greenkeeper Wayne Moore.
L’Ancresse then pulled away, as Steve Mahy defeated Philip Greham 2&1 and Jack Mithcell overcame Jason Byrne 3&1.
The dogged Royal Jersey contingent were up for the fight.
Paul Le Rougetel and Chris Huelin both won 5&3 against Sam Le Huray and George Melhuish respectively, leaving the game on a knife edge at 3-3 with Royal Jersey’s Sam Quail taking on Sean Mills.
Quail made par at 17 to close out the match 2&1.
