New York - Roger Federer and Rafael Nadal are just one step
away from a US Open semi-final clash but both face tricky challenges to set up
what would be their maiden encounter at Flushing Meadows.
Swiss Federer, chasing a record-extending 20th grand slam
title, takes on Argentine Juan Martin Del Potro, the man who beat him in the
2009 final in New York.
While Federer eased into the fourth round, 24th seed Del
Potro battled through five sets against Austrian Dominic Thiem and his flat
forehand could prove lethal against the former world No 1.
Current world No 1 Nadal faces the impressive Russian
19-year-old Andrey Rublev, a player who has shown no fear in his run to the
"I have a good shots. I can play really fast," the
teenager warned his 31-year-old opponent.
The first match of the day will see women's world No 1
Karolina Pliskova, who demolished Jennifer Brady 6-1 6-0 in the previous round,
face off against another American when she plays 20th seed Coco Vandeweghe.
Madison Keys, one of four Americans in the quarterfinals this
year, plays Estonian qualifier Kaia Kanepi, who is back to her best after
almost two years off the courts because of an injury and a virus.
