They did their chances of being CI team of the year no harm at all by beating title rivals Gloucestershire 2nds 11-4 at the New Gilson Hall at La Pouquelaye to take all three points and move six points clear at the top of Division II.
It was a victory which makes the Island team, under player/manager Mark Constable, firm favourites to win the league and claim their second successive promotion in the UK competition.
The home team got off to their usual good start in the singles with No 1s Constable and Kerry Coombs-Goodfellow cruising to comfortable victories.
Constable beat Jon Horsfield 15-1, 15-2 and Coombs-Goodfellow saw off Kerry Mullen 11-3, 11-3.
At No 2 Gavin Carter took the opening set against Mike Kennedy 15-7 but lost out in a tight second 14-17 before having to concede, with a re-occurance of a calf injury in the deciding set.
But Kim Ashton ensured Jersey took a 3-1 lead into the doubles with an 11-7, 11-4 defeat of Shy Tetrar.
Jersey continued to dominate despite Carter’s withdrawal from the doubles.
The top men’s pairing of Constable and Anton Kriel polished off both Gloucestershire pairs in straight sets and Coombs-Goodfellow and Lucy Burns further extended their unbeaten run with a three-set victory over Helen Hope and Jo Theyer, although Jersey’s second ladies pair of Ashton and Natalie White lost a close three-setter to Mullen and Tetrar.
Veteran Ian Coombs-Goodfellow ventured out of county retirement for the fourth time in two seasons to partner Clive Dunford.
They faced Horsfield and Yew in a thriller that lasted well over an hour.
The Gloucestershire pair snatched the opening set 15-13 only for Coombs-Goodfellow and Dunford to take the next by the same scorline.
In the decider the Jersey duo kept their cool for a nail-biting 17-16 victory.
They immediately followed this with a comfortable 15-2, 15-8 win over the Gloucestershire top pair of Kennedy and Corke.
On adjacent courts Coombs-Goodfellow and Burns defeated Mullen and Tetrar 15-8 in the third and Ashton and White went down in straight sets to Hope and Theyer.
So Jersey took a 9-3 lead into the three mixed doubles, needing one victory to take all three points and send the visitors home empty handed.
And the top combinations of Constable and Burns and Kriel and Coombs-Goodfellow both delivered again, in straight sets.
However there was some consolation for Gloucestershire when Horsfield and Tetrar defeated Dunford and Ashton 15-8, 15-1.
