Manchester City booked their place in the Women’s FA Cup final on Saturday with a 4-1 victory over West Ham.
Chelsea or Arsenal, who face off later this weekend, await in the Wembley showdown after Lauren Hemp struck twice in the second-half at Dagenham.
Lisa Evans had briefly put the hosts back in the match after goals from Ellen White and Chloe Kelly, before Hemp hit her 50th club goal and a stoppage-time sealer.
The visitors took the lead with 21 minutes gone when White reacted first to dive and head home, with keeper Mackenzie Arnold desperately scrambling back across her goal after the impressive Keira Walsh's 25-yard piledriver had come back off the crossbar.
White saw a second equally impressive effort chalked off after the officials ruled that Lucy Bronze had not kept the ball in play before she crossed, and Hemp, who had been well marshalled until that point, fired over as City started to turn the screw.
They got their reward eight minutes before the break when Kelly ran on to Gilly Flaherty's ill-judged pass across her own penalty area to beat Arnold and make it 2-0.
However, Evans gave the Hammers hope three minutes before the break when, after Alex Greenwood had been dispossessed on halfway, she capitalised on hesitancy in the City defence to round Ellie Roebuck and reduce the deficit.
White saw a 52nd-minute header correctly ruled out for offside as the visitors looked to kill off the game, but West Ham defended resolutely to keep themselves in with a chance.
They might have been level when Evans slid Tameka Yallop in behind the visitors' defence, but she stabbed her attempt wide as Roebuck closed her down and their hopes were ended by Hemp when she turned smartly before thumping a shot past Arnold.
Katerina Svitkova forced a late save from Roebuck, but Arnold had to tip substitute Filippa Angeldahl's fierce drive on to the crossbar and was beaten for a fourth time at the death as Hemp completed a good afternoon.
