One break of serve, and a mini-break, was all Roger Federer needed to win his opening match at the season-ending ATP Finals on Sunday.
The 19-time Grand Slam champion broke Jack Sock in the first game of the 6-4, 7-6(4) victory at the O2 Arena. Both then held serve the rest of the way.
The 36-year-old Federer, ranked No. 2 in the world and won the Australian Open and Wimbledon this season, is the oldest player ever to qualify for the season-ending tournament, which started in 1970.
Federer broke Sock, who was making his debut at the tournament, in the very first game, hitting a backhand winner to take the 1-0 lead.
That was the only break point for either player in the first set. But Federer had plenty more in the second set — five, to be exact. He just couldn’t convert them.
In the tie-breaker, Federer went ahead 3-2 with a mini-break, but Sock got it back. After another to make it 5-4, however, it was nearly over. Federer won the final two points on his serve to go to 1-0 in the round robin.
The result: Group Boris Becker: Roger Federer (Sui) bt Jack Sock (USA) 6-4, 7-6(4).
