Swansea City Ladies celebrate (@SwansLadies Twitter)
The Bluebirds won at Port Talbot meaning Hayley Williams' side are now out of the running for second spot. Joel Hutton's team claimed all three points, thanks to a solitary goal from striker Alana Murphy, who scored her 11th league goal of the campaign.
It was an easier afternoon for Ian Owen's Swansea City, who were 6-0 up at the break against neighbours Briton Ferry. The recalled Stacey John-Davis netted a first half hat-trick after only 22 minutes and Nieve Jenkins was also on the scoresheet, heading in a Katy Hosford corner after 24 minutes.
Jodie Passmore scored the Swans' fifth after the break, before stand-in skipper Emma Beynon scored twice.
