British teenager Emma Raducanu reached the US Open final as her rise continued with a stunning straight-set win over Greek 17th seed Maria Sakkari in New York.
Raducanu extended her dream run with a 6-1 6-4 victory in which her dominance again almost defied belief.
She is the first qualifier to reach a Grand Slam final and will play another teenager Leylah Fernandez on Saturday.
Raducanu is the first British woman in a major single final in 44 years.
