Australian Nick Kyrgios hinted that he could retire at the age of 27 due to the mental health struggles he suffers over his volatile form, despite beating world number one Daniil Medvedev to book a US Open quarter-final spot.
Kyrgios slammed his racket twice in frustration after allowing reigning US Open champion Medvedev back into the match during his stunning 7-6 (11), 3-6, 6-3, 6-2 win. Despite recording a surprise victory Kyrgios was left reflecting on the mental health issues tennis gives him and hinted at not playing again after this tournament.
"I've been in some really tough situations mentally, and in some really scary places," he said.
