DESPITE losing his serve in the first game and two match points, Switzerland’s Roger Federer has crept past 21-year-old Karen Khachanov in two sets on day four of the Hopman Cup.
The Russian went down 3-6 in the first set but took the world number two to a thrilling second set tie breaker in front of a record 13,943 crowd.
Federer dropped two match points but claimed victory after an unsuccessful line challenge from Khachanov.
“I thought it was in when I looked at the mark on the floor so when it was out it was a surprise,” Federer said.
The duo went head to head for the first time last year when Federer triumphed 6-4 7-6.
Federer said he enjoyed the intensity of the match, which became a serving exhibition at one stage.
He is confident he will come up against Jack Sock, who beat Khachanov on Saturday, in two days time despite the American retiring injured from today’s game against Yuichi Sugita from Japan.
