New York - Roger Federer returns to action under the lights
at the US Open on Monday with confidence after he breezed into the fourth round
following two five-set thrillers.
The third-seeded Swiss, chasing a record-extending 20th
grand slam title, faces German veteran Philipp Kohlschreiber, a man he holds a
perfect 11-0 career over.
Federer believes his back problems are behind him and that
he can look forward after easily beating Feliciano Lopez in the third round.
"I needed to get over the fear of the back issue. Then
I think the wobble I had in the second round was due to my preparation,"
"I think now I'm just trusting my movement better. My
serve is there. My mind is there. I can finally focus on playing tennis and not
so much about the past."
Opening proceedings on Arthur Ashe Stadium are world No 1
Karolina Pliskova and Jennifer Brady, who is one of three American women hoping
to join Sloane Stephens and Venus Williams in the last eight.
Also on centre court, CoCo Vandeweghe takes on Czech Lucie
Safarova and Madison Keys faces fourth seed Elina Svitolina of Ukraine, pushing
the heavy-hitters' contest between former champion Juan Martin del Potro and
Austrian sixth seed Dominic Thiem to the Grandstand.
World No 1 Rafael Nadal, who is on a semi-final collision
course with Federer, takes on Ukraine's Alexandr Dolgopolov in the second match
at Arthur Ashe stadium.
