Nick Kyrgios complained of shoulder pain but played like the picture of health as he defeated Brandon Nakashima 4-6, 6-4, 7-6(2), 3-6, 6-2 on Monday to start the second week of Wimbledon with a place in the quarter-finals.
The Australian who thrived on confrontation during his ill-tempered win two days ago over Stefanos Tsitsipas, came up against a calm 20-year-old opponent who gave little opportunity for drama.
Despite repeated visits by the trainer and a handful of painkillers from the doctor, Kyrgios still managed 35 aces in his 10th grass win of the season in three hours, 11 minutes..
By reaching the last eight, Kyrgios duplicated his Wimbledon debut performance of 2014 when he beat Rafael Nadal in the fourth round before losing to Milos Raonic.
