In front of a record crowd of 12,471 at Cardiff City Stadium, Wales got the point they needed from a tense goalless draw with Slovenia.
Slovenia needed a win to progress instead of Wales, Mateja Zver was denied by Laura O’Sullivan early on and also fired inches over, to turn up the tension.
Carrie Jones forced a save from Zala Maršnik, who also denied Angharad James on her 100th appearance.
Gemma Evans nearly made the breakthrough on 71 minutes, but her header was punched off the line by the keeper.
Elsewhere in the group, France beat Greece 5-1 and Estonia won 2-0 in Kazakhstan, ahead of the play off draw which takes places on Friday at 12:30pm UK time.
