Nick Kyrgios said he hopes he «never again» has to face his good friend, Thanasi Kokkinakis, at a Grand Slam after his first-round victory at the US Open, while Stefanos Tsitsipas sensationally crashed out in his opener. It was a straightforward victory for Kyrgios as he swept past Kokkinakis in straight sets, 6-4 6-4 7-6(4), and he will now be able to take on opponents with more relish in New York. Ad Perhaps surprisingly, the duo — who customarily play doubles together, winning their home Australian Open back in January — were meeting for the first time ever in a tour singles match, and it was clear for all to see how Kyrgios did not enjoy facing his compatriot on Arthur Ashe Stadium.
