Nick Kyrgios revealed how many times he has been drug tested amid his criticism of World number one Jannik Sinner.
The Australian has been vocal with his feelings towards the Italian since he tested positive for banned substance clostebol on two occasions.
The 29-year-old became even more upset when Sinner did not receive a ban and was cleared of intentionally taking the substance.
Kyrgios has not been afraid to make his views known on social media which has drawn ire from members of the tennis world, such as Andy Roddick.

What has Nick Kyrgios said about being drug tested?
Nick Kyrgios has spent plenty of time talking about Jannik Sinner’s drug tests, but now it was time to talk about his own experiences of being drug tested.
During his pre-Australian Open press conference a reporter asked the former World number 13 for his views on having to think about drug tests and that side of being a professional athlete. This is when Kyrgios revealed how often he is drug tested, before praising his team.
“I don’t want to speak too much about it. I think we’ve all been speaking about it. I feel like that’s the only thing tennis has been speaking about the last six months,” he began.
“But for me, to answer your question, like, I mean, I’ve been tested four times in the last couple months. I got tested in my home three days ago. For me, it hasn’t been a problem at all in my career.
“I’ve been on the tour now for 10-plus years. For me, I’m not worried at all ’cause I know that I’m really, really on top of what’s going on in my team. I’m very confident in myself that I’m not going to be accidentally putting something in my system.”
Andy Roddick criticises Nick Kyrgios for behaviour towards Jannik Sinner
Kyrgios has developed a reputation for being very outspoken and unfiltered, especially where Sinner’s failed drug tests are concerned.
On an episode of his ‘Served podcast’ released on Tuesday, Roddick did not hold back on his assessment of Kyrgios’ behaviour towards Sinner.
He also took umbrage with Kyrgios taking aim at teenager Cruz Hewitt, the son of Lleyton Hewitt, who posted a photo with Sinner after practicing with him ahead of the Australian Open.
“I have decided to lay off because there is this weird thing where he wants the likes. At this point he is a tennis influencer. He lives for likes, he lives in the comments section,” Roddick said.
“But what I have an issue with is the hypocrisy with which he picks and chooses when to levy judgement on others while also wanting you to digest the context of his comments – the latest being towards Cruz Hewitt who practiced with Jannik Sinner.
“Imagine as an almost 30 year old man, going into the comments of a 16 year old who is the best player in the world. That’s a big moment and to simply post a picture and then have this guy go into the comments and make it all about himself. ‘I thought we were bros’.
“The defence was all made that it was a joke. The lack of awareness you have with bringing trolls and all of the worst of tennis fandom into a 16 year old’s comments is ridiculous. It’s ridiculous.”
