World no. 2 and six-time champion, Roger Federer got off to a positive start as he defeated debutant, Jack Sock 6-4, 7-6(7-4) at the 02 Arena, London.
The 36-year-old Swiss who’s making his 15th appearance at the ATP Finals was given a thorough workout by Sock although had he been a little more clinical the scoreline would have been more heavily-weighted in his favour.
“It’s always a struggle in the first match of any tournament,” Federer said. “I got off to a great start, my big hope was I was going to be able to play a bit more freely after that.”
“The second set was tight, I missed some opportunities, the breaker could have gone either way and in the end he helped me with some double faults and some mistakes.”
For Jack Sock, it’ll be the first time in four meetings he’s managed to take Federer to a tie-break, but a double fault at 4-5 handed Federer a match point he clinically converted.
The American will now be looking to do well in his other group matches in order to have a shot at glory.
