Ailing Nick Kyrgios prevails at Wimbledon, advancing to 3rd career Slam quarter-final

Much quieter, much calmer than in his previous match, Nick Kyrgios overcame a troublesome right shoulder to deliver 35 aces and beat Brandon Nakashima 4-6, 6-4, 7-6 (2), 3-6, 6-2 at Wimbledon on Monday to reach a Grand Slam quarter-final for the first time in 7 1/2 years.

The unseeded Kyrgios improved to 6-0 over his career in five-setters at the All England Club and collected his tour-leading 11th grass-court victory of the season.

"I need a glass of wine, for sure, tonight. For sure," Kyrgios told the crowd during his on-court interview in London, after swapping out his rule-conforming white hat and shoes for red versions.

Playing before a nearly full house at Centre Court, the 27-year-old Australian only occasionally displayed his unusual repertoire of trick shots -- a between-the-legs swing here, an underarm serve there -- or the temper that earned fines of $10,000 US for spitting in the direction of a heckling spectator at the end of his first-round match and $4,000 for an audible obscenity during his tempestuous win against No. 4 seed Stefanos Tsitsipas in the third round.

Against Nakashima, an unseeded 20-year-old from California, Kyrgios repeatedly was visited during changeovers by a trainer, who massaged and manipulated his shoulder. There was a stretch where Kyrgios' high-speed serves dipped from above 217 kilometres per hour to closer to 177, but he eventually seemed to get past that and was back to producing unreturnable offerings over and over.

After Nakashima evened things by taking the fourth set with a break, then went up 1-0 in the fifth, Kyrgios surged to the finish. He earned five games in a row, before serving it out and closing this way from love-30: cross-court forehand passing winner; hanging in on
