Nick Kyrgios and Jack Sock have kept Team World within reach after beating Rafa Nadal and Stefanos Tsitsipas in doubles match.
A pumped-up Kyrgios and Sock teamed up to overcome Rafael Nadal and Stefanos Tsitsipas 6-4, 3-6, 10-6, to secure two crucial points and leave the overall score at 7-5 in favour of the Europeans.
The World pair took the first set but Nadal and Tsitsipas fought back to level in the second and final set, forcing the match to go to a match tiebreaker.
But Sock and Kyrgios reasserted their dominance and reduced Europe’s points advantage going into Sunday.
Earlier, Nadal defeated Raonic 6-3 7-6(1) and Federer maintained his 100% Laver Cup record against Kyrgios with a thrilling 6-7(5) 7-5 10-7 victory.
Nadal, who had helped Federer to victory over Kyrgios with some tactical pointers, was made to work hard by Raonic but he played the bigger points much better.
Playing in front of 17,000 fans in Geneva, home favourite Federer beat Kyrgios for the third time in as many editions of the competition to take Europe closer to the 13-point victory target ahead of the night session that features Rafa Nadal.
“The crowd could feel it, I could feel it. I needed to get some energy going but you can’t do that if you don’t play any good shots and Nick was playing very well. I was just trying to stay focused. If you can turn the momentum, the crowd gets back into it and I need some earplugs next time, it was just phenomenal” said Federer.
The third annual Laver Cup will be decided on Sunday by a doubles match and then three singles matches – each worth three points with 13 needed for overall victory.
