Porter danced her way through the Saints’ defence numerous times to score all four goals as Jersey Wanderers defeated the Channel Islands and Jersey champions 4-3 at the Hockey Club.
Wanderers manager Mike Freer said: ‘St John were players short but so were we so full credit to my girls it was an excellent performance.
‘Kathryn displayed great commitment and tenacity and her all round performance was probably her best in 18 months.
‘One time in the second half there were five St John players chasing her – it was funny because they were running flat out and they had no chance of catching her.’ Porter scored a last-minute winner after St John led 2-1 at half time following goals from Lori Moran and Rachel Bowker.
Wanderers then took the lead until Becky Darts equalised with five minutes left.
Sim Sains and Fiona Gildea had excellent games in Wanderers’ defence while Helen Durkin again excelled with a captain’s performance.
St John, who were with eight regulars, struggled to field 11 and they included two who had just run the first leg in the Jersey Marathon.
Manager Jason Lee said: ‘Wanderers deserved their win and on that display I see no reason why they can’t beat the other top teams in the division.’ St Brelade too were heavily affected by the Jersey Marathon and injuries.
There were seven absentees through injury with four returning from the Marathon to play having run five and a half miles.
Tower defeated St Brelade 17-0 after goals by Jodie Botterill (five), Lara Couvert (three), Leanne Bell (two), Lauren Jéhan (two), Louise Vandervliet (two), Rebecca Bichard, Lisa McLaughlin and Danielle Evans.
St Peter won 4-1 at home to Grouville.
Andrea Roe fired the hosts home after just two minutes.
Leticia Abreu made it 2-0 following good work by Susan Stewart.
Grouville had some pressure but it was the Saints who scored again through Roe with a fine solo effort.
Stewart finished off a weaving run from an acute angle to make in 4-0 before Grouville bagged their consolation before half time through Ebonnie Hotton.
