Nick Kyrgios has caused outrage with a comment about his ex-girlfriend Anna Kalinskaya; some tennis fans are calling for the Australian agitator to be fired as a commentator.

On Saturday, the 29-year-old captioned a photo of himself and Kalinskaya at an LA Lakers game in 2020 with the caption “second serve.”

It is not entirely clear what Kyrgios meant with the comment, but many fans see it as a dig at Italian superstar Jannik Sinner – who is now in a relationship with Kalinskaya.

In recent weeks, Kyrgios has been vocal in his criticism of Sinner, insisting that he should be banned after two positive doping tests.

Sinner tested positive for the banned anabolic steroid clostebol during the Indian Wells tournament on March 10 and then again just eight days later.

The Italian was provisionally suspended but successfully appealed and was allowed to continue playing on the ATP Tour while the International Tennis Integrity Unit reviewed all the evidence.

Sinner’s explanation for the ingestion of the banned substance into his body was that his physiotherapist Umberto Ferrara had used a spray containing Clostebol to treat a wound on the tennis star’s finger.

The 23-year-old’s team said Ferrara bought the spray in Italy, one of the few countries where products containing Clostebol are available without a prescription.

Kyrgios’ comments polarized his fans: some agreed with the Australian, others accused him of jealousy because Sinner was now with his former partner Kalinskaya.

His recent social media comment has prompted some fans to call for his firing from ESPN.

“ESPN, Kyrgios is a misogynist. His tennis career is over and he has no respect for the players or the game. Get rid of him,” one fan posted on X.

“It’s disgusting that ESPN allows Kyrgios to interview the tennis players after he said horrible words against Jannik Sinner and the sexist joke against Anna Kalinskaya,” another replied.

“Also, it’s absolutely disgusting that @espn continues to employ a misogynist like Kyrgios,” posted a third.

Kyrgios, who is currently dating Costeen Hatzi, says he has no personal problem with Sinner but admits he would find it difficult to overlook the saga should the two ever meet on court.

The Italian Sinner was cleared of any wrongdoing after a failed doping test earlier this year.

“It’s nothing against Sinner personally. He is one of the best tennis players we have at the moment. I don’t deny that. Nothing against him personally,” said Kyrgios.

“I’m definitely not going to be as warm and welcoming as I used to be. I just want a level playing field for everyone. That’s what this fight is for.”

“I was tested two days ago in my hotels. We are tested regularly. This is a sport I have played all my life. When the conditions are not the same for everyone, the integrity of the sport is lost a little.”
