Three-time champion and eighth seed Venus Williams has been knocked out of the Miami Open in the quarter-finals by qualifier Danielle Collins. The 24-year-old, ranked 93rd in the world, needed only one hour 29 minutes to come through 6-2 6-3 against fellow American Williams, 37, a seven-time Grand Slam winner.
It was Collins' first victory against a top 10 player. She will now face French Open champion Jelena Ostapenko in the semi-finals.
The 20-year-old Latvian saw off world number four Elina Svitolina over two tie-breaks, winning 7-6 (7-3) 7-6 (7-5).
"The first time I saw Venus in the locker room I nearly cried," Collins admitted. "She has been my favourite player so I am finding it difficult to wrap my head around this."
Victoria Azarenka will play US Open champion Sloane Stephens in the other women's singles semi-final.
