Jannik Sinner admits he 'didn't understand' Nick Kyrgios fury in Miami Open clash
Jannik Sinner has admitted he didn't understand why Nick Kyrgios launched a tirade at the umpire during their round-of-16 match at the Miami Open. The ninth seed defeated the Aussie 7-6(3) 6-3 in their first meeting, benefitting from a point penalty and game penalty after Kyrgios received two code violations for his on-court behaviour.
