(Reuters) - Roger Federer and Novak Djokovic were at their dominant best at the U.S. Open on Friday as both cruised into the round of 16 with straight-sets victories.
After making sluggish starts in his previous two matches, five-times winner Federer took his game up a notch to power past Briton Dan Evans 6-2 6-2 6-1 under the open roof at Arthur Ashe Stadium on a sunny day.
