It’s the quarterfinal match up that everyone was hoping for and Serena and Venus Williams duly delivered Sunday at Flushing Meadows.
First up on the Arthur Ashe Stadium Court, elder sister Venus wasted little time in beating 152nd-ranked Estonian teen qualifier Anett Kontaveit 6-2 6-1 in a one-sided encounter, taking less than an hour.

Later, top seed and grand slam seeking Serena dispatched fellow American and 19th seed Madison Keys, winning 6-3 6-3 with a single break of service in each set.
It kept her on course for the calendar grand slam, last achieved by Steffi Graf in 1988.
If she lifts the title Serena would also draw level with the German on 22 grand slam singles titles.
But first she must get past her sister Venus, who has found a new lease of life at 35, having not progressed so far in a grand slam since reaching the semifinals of the U.S Open in 2010.
