Coco Gauff was 15 when she announced herself as a future Wimbledon champion, coming through qualifying, beating five-time winner Venus Williams and reaching the fourth round.
That was seven years ago. Until this week, while she has won grand slams in Paris and New York, the fourth round remained her high-water mark in London.
On Tuesday (local time) she finally booked a semi-final place, defeating fourth-seed Jessica Pegula 4-6 6-3 6-3 to become the highest-ranked woman left in the draw.
