Arsenal stayed on track for a domestic treble with a 4-0 win at Liverpool.
Ciara Grant, an early substitute for the injured captain Faye White, headed Arsenal in front from a ninth-minute Kim Little corner.
Striker Ellen White twice went close to increasing the lead as the visitors controlled the first half and she finally got the goal she deserved eight minutes after the break.
White raced onto a pass from Jordan Nobbs to drive an angled shot just inside the far post.
Within 12 minutes the tie was over as another sub, Jennifer Beattie, tapped in from close range following a fine run and pass from striker Danielle Carter.
Beattie grabbed her second goal a minute from time, again with a simple finish from inside the six-yard box.
