Spartans beat Hearts Ladies 4-0 to pip their city rivals to the final top-six slot in the Scottish Women’s Premier League.
The Jambos will now face a fight for the top-flight status.
Three goals in six first-half minutes from Sarah Ewens (two) and Louise Mason did the damage, while Michelle Russell added the fourth after the break.
Spartans boss Debbi McCulloch said: “The pressure was on us after we got ourselves into this situation and there was a nervousness for some, however the players stepped up when we needed them to.
“It was important to get the first goal and after that we were able to relax. Getting three goals in six minutes meant Hearts had no option but to come at us.
“We’ve recovered from a poor start, where we had some changes to the side.”
Hearts manager Grant Scott said: “For us, a newly promoted side, to take the fight for the top-six into the final game before the split is an incredible achievement. Our aim now reverts back to what it was at the start of the season – to finish in the top two of the bottom six and secure SWPL football for another season.”
Edinburgh’s other clubs had mixed fortunes: Hibs Ladies thrashed Inverness City 8-0 but Hutchison Vale lost 4-0 away to Forfar Farmington.
