Havant are facing a relegation decider in South Clubs’ Women’s League division one.
The Barncroft Way strugglers were beaten 2-1 at Woking in their penultimate league match on Saturday.
But they have one final chance to retain their top-flight status when they host rivals Guildford next weekend.
Rock-bottom Havant are three points adrift of the Surrey side but the two clubs boast the same goal difference.
That means victory for Havant will be enough to see them condemn Guildford to division two.
A switch in tactics, which bolstered their midfield, helped the visitors rally from 2-0 behind at Woking.
After player-of-the-match, keeper Lauren Wake, had been beaten for a second time, Nicky Wright brought the best out of the home stopper when her fierce drive was tipped onto the woodwork.
Steph Lurshay eventually found a way through, striking high into the net.
But Havant ran out of time to notch the leveller their pressure and teamwork deserved.
The ladies’ second string beat Southampton II 4-0 in Hampshire League division one.
Laura Howe, Zoë Stride, Sophie Brigg and Ali Locke were all on target.
