Nick Kyrgios was given a warning for unsportsmanlike conduct for yelling at a ballkid during his 7-6(6), 7-6(6), 6-4 win over Italian Marco Cecchinato.



The Aussie disagreed with the call and took some time to plead his case with the veteran umpire to no avail.



Kyrgios, seeded 17th, advances to face Igor Sijsling of the Netherlands in the second round.
