Actually, it was nice. Because he was serving unbelievable. So, I was like, ‘Ok, what’s the chance to get a match point?’ But again, I was not expecting it. So, I had to be fast on the feet. But wow, what a match,” Holger Rune said in his on-court interview.Rune is through to the second week of Wimbledon for the first time in his career, in just his second appearance at the event. The Dane now awaits the winner of Frances Tiafoe and Grigor Dimitrov in the fourth round.
