Wales set up a winner-takes-all game against England in the race for Women's 2019 World Cup qualification after beating Russia 3-0.
Kayleigh Green scored twice and made a third for Natasha Harding as Wales - who achieved a seventh successive shut-out in the competition - reclaimed top spot in Group One.
England are now a point behind Wales with a game in hand, and their visit to Jayne Ludlow's side on August 31 will determine who claims a place at the 2019 World Cup in France.
Rachel Rowe brought a save from Russia goalkeeper Elvira Todua as a first half of few chances failed to hint at the drama to come.
Green, as she had done in scoring the winner against Bosnia and Herzegovina last Thursday, fired Wales ahead after 48 minutes when she smashed home an angled effort from close range.
The Yeovil Ladies striker then finished off an excellent 61st-minute team move and Helen Ward's assist with a cute lob over Todua.
Harding finished off Russia from Green's through ball seven minutes later to guarantee Wales at least second place in the group and a possible play-off spot.
