Venus Williams in orbit at the US Open, where she has reached the semi-finals, and the tie ensures there will be at the very least one American in the final, as her opponent will be fellow American Sloane Stephens.
Venus had to fight against the Czech Republic’s Petra Kvitova to make it through, while the unseeded Stephens was also taken to three sets by Latvia’s Anistasija Sevastova to reach her second Grand Slam semi-final.
For American tennis fans the tantalising prospect remains on for an all-American semis, which has not happened since Wimbledon 1985.
In the lower half of the men’s draw no player is seeded higher than Pablo Carreño Busta at 12, and he saw off Diego Schwartzman to be the first man into the semis, along with Kevin Anderson, who beat the big-serving Sam Querry.
Top Seed Rafael Nadal is expected to join them with only the unseeded Russian Andrey Rublev to overcome, but the quarter final everyone is now waiting for, a candidate for match of the tournament, is surely Roger Federer against Juan Martin del Potro.
For all the third seed’s brilliance, Del Potro has won the New York crowds’ hearts, and is desperate to regain the title he won here aged 20 in 2009, when he beat prime Nadal and then Federer back-to-back.
