LONDON — Roger Federer recovered from a sloppy start to outclass Czech Tomas Berdych 6-4 6-2 as he began his 14th consecutive ATP Tour Finals appearance in impressive fashion on Sunday.
The Swiss world number three, bidding to win the year-ender for a seventh time, served a two double-faults in his opening service game as he was broken to love, but quickly recovered to leave Berdych floundering.
Berdych did lead 4-3 on serve in the opener but 34-year-old Federer then reeled off seven games in a row, treating a full house at the O2 Arena to his usual showreel of winners from all corners of the court.
