Another outburst from naughty Nick
Already on notice from Australian Olympic Committee officials for his behaviour, Nick Kyrgios did himself no favours in his 7-6 7-6 6-4 win over Italian Marco Cecchinato in the first round of the French Open.
The Aussie was given a code violation by experienced chair umpire Carlos Ramos for shouting "towel" at a ball boy toward the end of the tense first set.
The incident prompted a clearly unhappy Kyrgios to compare the response to a recent incident at a match in Rome involving world No.1 Novak Djokovic, who went unpunished after pushing umpire Carlos Bernardes away by the arm during a debate about a line call.
"So when Djokovic pushes an umpire that's all right?" he said to Ramos during the first-set tiebreak.
"I say towel out loud and I get a code. That's unbelievable bias, man. Unbelievable.
"But when Djokovic pushes an umpire out of the way that's all right? Tell the whole world that's all right."
Asked about the incident during his post-match press conference, Kyrgios was much calmer.
"I thought it was a little bit rough. I can't do anything about it now," the 17th seed said. "Obviously it was just his personal opinion on how he thought that I went about it, but, I mean, it is what it is."
Kyrgios will face Igor Sijsling in the second round after the Dutchman beat unseeded Romanian Adrian Ungur 6-1 6-2 7-6.
Only a handful of matches were completed on the opening day after heavy rain forced play to be abandoned.
