PARIS—American Jack Sock, who will play Rafael Nadal in the fourth round of Roland Garros, is good friends with young Australians Thanasi Kokkinakis and Nick Kyrgios, both of whom lost in the third round. Kokkinakis, 19, lost to world No. 1 Novak Djokovic, while Kyrgios, 20, was beaten by No. 3 seed Andy Murray.
“We're all friends. I've spent time with Thanasi and obviously spent a lot of time with Nick the last few weeks,” said the 22-year-old Sock, who is playing doubles with Kyrgios. “Played a ton of FIFA and had a ton of Chipotle. Before we played doubles in Rome I didn't know him very well at all. We played last summer in the Challenger, and that was kind of the extent of your relationship, hanging out, friendship, whatever it is. Then started playing doubles in Rome. Played 500 games of ping-pong that week and a lot of FIFA. Obviously developed a very good friendship, and now we're very close.
“It's good for all of us any time you have these younger guys making third rounds, and obviously some of us hopefully be in the fourth round,” said Sock before his third-round win over 18-year-old Borna Coric. It's good for the sport I think and good for us as well to keep pushing each other.”
