Kyrgios won the 2019 Mexican Open in Acapulco (his fifth title), after beating three top 10 players (i.e. Nadal, Isner and Zverev) and three-time Grand Slam champion Stan Wawrinka, en route.[72] His Miami Open campaign was full of controversy: a victory over Dušan Lajović in the third round involved two successful underarm serves and an altercation with a spectator, and the follow-up loss to Borna Ćorić in the round of 16 involved another argument with a spectator and both players smashing racquets.[73] Following his loss, he acknowledged his opponent's more disciplined nature and questioned his own motivation.

The investigation ended on September 26, and he was issued a 16-week suspended ban, a $25,000 fine, and a six-month probationary period.[79] Although Kyrgios had corrected his comments by saying that "corrupt" was not the right choice of words, the ATP explained that a second investigation had taken place after his comments at the US Open.[80]

Kyrgios qualified for his first Olympics at Rio 2016 but withdrew from the event due to differences with the Australian Olympic Committee.[119] Kyrgios said in July 2021 that he would not compete in the Tokyo 2020 Olympic Games.[120]

Kyrgios first used the underarm serve at the 2019 Mexican Open during his match with Rafael Nadal, who subsequently claimed it was not within the spirit of the game, and accused Kyrgios of "lacking respect" for his opponent and the crowd.[126]

In contrast, Daniil Medvedev used an underarm serve against Alexander Zverev in their group encounter at the 2020 ATP Finals, afterwards remarking that:[126]

"Some people used it before, but of course now with especially Nick (Kyrgios) and (Alexander) Bublik, it became really a part of tennis," said Medvedev. "I see nothing disrespectful of it."

Kyrgios has been credited for reintroducing the underarm serve into the ATP tour, and he has now used the underarm serve more frequently than any other player in professional tennis.[127][128]

Kyrgios won his first challenger tour title at the age of 17.[31] His childhood coach, Andrew Bulley, said he was a "super competitor" who "trained with a better intensity than the other kids. He always turned up and gave it 100 per cent." His parents used to take him to every regional competition in Australia they could enlist him in. As an 18 year old, his father George Kyrgios, said: "As a junior he was always playing older kids and you could just see him adjusting. He's a perfectionist and has been pretty hard on himself along the way."[146] Top French player, Richard Gasquet, beat the 18 year old Kyrgios in the 2014 Davis Cup World Group tie and said afterwards: He's got a great attitude and a wonderful personality. I think he will be a prominent player in the future.[147]

Andrew Bulley believes the support of Kyrgios' close knit family was a critical factor in his attitude and motivation at the time.[148] He was close to his family and friends, but as he rose through the rankings, playing in tournaments all over the world meant that he was away from home for long periods. He said: “I was winning, losing, going through relationship problems, dealing with other problems and I was pushing (family) away because you feel like the world’s against you. I’m going seven months a year abroad in a new place every week. That’s why tennis is so hard in my opinion."[149] According to his mother, Nill Kyrgios, this was a very hard time for her son as a result of the criticism and pressure he was under.

Kyrgios is now known as a talented but mercurial[150][151][152] and hot-tempered player.[153][154][155] He has been accused of tanking, verbal abuse, and unsportsmanlike conduct by umpires, match referees, the media and by former tennis players, including John McEnroe.[156] In 2019, the Associated Press described Kyrgios as "a volatile sort who has repeatedly got in trouble for on-court actions".[157] He is also known for his authenticity[158] and individuality,[62] and has been described by three-time Wimbledon champion John Newcombe as an "exceptional talent" and "a real individual".[62]

Kyrgios has openly said that he "does not love tennis" and has a greater interest in basketball.[159] He openly critiqued his dedication to the sport after his exit at the 2017 US Open to fellow Australian John Millman, saying that he is "not dedicated to the game at all" and "There are players out there that are more dedicated, that want to get better, that strive to get better every day, the one-percenters. I'm not that guy."[160] At the 2015 Wimbledon Championships, after he failed to return numerous serves, Kyrgios was accused of tanking—deliberately not playing up to his abilities—during the second set of his fourth-round loss to Gasquet. Kyrgios was booed by the crowd for his perceived lack of effort, but denied the accusations, stating "of course I tried".[161]

In October 2016 Kyrgios was fined $32,900 (on top of an earlier fine of $21,659—$13,127 for lack of effort, $6,563 for verbal abuse of a spectator, and $1,969 for unsportsmanlike conduct) and banned for eight weeks for "lack of best efforts" against unseeded Mischa Zverev in the second round of the Shanghai Rolex Masters.[162] He threw the match 6–3, 6–1, in 48 minutes,[163] at one point asking the umpire: "Can you call time so I can finish this match and go home?" When later asked during a press conference if he thought he owed the fans a better effort, he responded: "What does that even mean? I'm good at hitting a tennis ball at the net. Big deal. I don't owe them anything. If you don't like it, I didn't ask you to come watch. Just leave."[164]

Some commentators believe Kyrgios is more committed than he claims. After a string of successes in 2017, Kyrgios attributed his greater consistency that year to an improved work ethic. He said: "I've made an effort to try and put in the work every day. It hasn't been easy."[165] However, he continues to cause controversy on the court. Hugh van Cuylenburg, founder of the Resilience Project in Australia says Kyrgios is deliberately provocative and thrives when there is chaos around him: “Some people thrive in a hostile environment because it tricks them into the right level of arousal and reminds them of how much they care and how much they want to win – and Kyrgios is one of those.”[166]

Kyrgios produced some of the best performances of his career at Wimbledon in 2022. After losing to Djokovic in the final, Kyrgios said: “It’s taken me 10 years – almost 10 years – in my career to finally get to the point of playing for a grand slam and coming up short, but my level is right there."[167] When asked if this had made him hungry for more grand slam finals, he replied "no, it was exhausting!", provoking laughter among the crowds.

John Newcombe, former Australian world No. 1 in both singles and doubles, remarked that: "Nick is an exceptional talent and he doesn't beat to the same drum as everyone else – he's a real individual."[62]

Tim Henman, former British No.1 (1996, 1999–2005) prior to Andy Murray, stated that: "Kyrgios is a performer, an entertainer and will go out and play the tennis he is capable of. He can beat anyone because he is seriously talented. He is a bit different and speaks his mind."[62]

Paul Annacone, Roger Federer's former coach, has been quoted as saying: "I think Nick is the most talented player since Roger jumped on the scene”.[168]

Novak Djokovic after beating Kyrgios in the 2022 Wimbledon final: "I really respect you a lot. I think you are a phenomenal tennis player and athlete, an amazing talent."[169]

Coco Gauff, during a press-conference at Flushing Meadows, praised Kyrgios for practicing with her at the Miami Open despite already having concluded a two-hour long practice with Frances Tiafoe, noting that:[170]

“I know there's things on the court that he does that people don't agree with. I probably don't agree with some things,” Gauff said. “But it's just things like [hitting with a young kid] that stands out for me."

"It's just moments like that that people don't really see about him. So I think people paint him as a bad guy. I feel around the grounds, at least my experience of him, he's not."

"If he keeps it up, I think he can go far ... I always, always root for him, no matter who he's playing, to be honest."

John McEnroe has also praised Kyrgios's talent. In late 2018 on the Seven Network's Sunday Night show in Australia, McEnroe said that Kyrgios is "the most talented player [he's] seen in the last ten years" but that Kyrgios may "run himself out", if he continued not to commit himself to tennis.[171][172] While hosting a radio call-in show during the 2021 Wimbledon Championships on BBC Radio 5 Live McEnroe stated that if he could choose any player on the current tour to coach he would pick Kyrgios.[173]

However, McEnroe has also criticised Kyrgios's behaviour several times. Following his loss to Murray at the 2016 Wimbledon championships, McEnroe criticised his temperament, saying: "Kyrgios has to look in the mirror if he wants to become a top player and win Slams." He questioned his attitude towards the sport as Kyrgios was reportedly seen watching compatriot Hewitt in a doubles match shortly before his match with Murray.[156]

Two months later and following his exit from the US Open, Kyrgios was further criticised by McEnroe. He called on Kyrgios to retire from the sport, saying: "Nick Kyrgios, if you don't want to be a professional tennis player, do something else." The comments came shortly after his third round defeat by Illya Marchenko, in which he retired due to a hip injury. McEnroe commented: "He's hurt because he's not training enough."[174]

Those who know Kyrgios personally say his off-court personality is very different from his on-court antics. Hugh van Cuylenburg, founder of the Resilience Project says:[175]

“Everyone who has ever met him say he’s a sensational person who cares deeply about other people. He doesn’t seek recognition or publicity for the good things he does."

On a similar note, fellow Australian, Jason Kubler, said:[176]

“Every time I see him, he’s smiling. Every time I’m around him, it seems like I’m laughing. So it’s kind of weird when I read or see the comments about him, knowing him the way I do. He's just one of those people if you were to hang around him or spend any sort of quality time with him, you’d fall in love with him.”

Kyrgios pledged to donate $200 for every ace he served during the summer, which was subsequently taken up by other Australian tennis players.[177] Kyrgios also asked Tennis Australia to hold an exhibition match before the 2020 Australian Open to raise more funds.[178] Numerous top tennis players participated including Caroline Wozniacki, Serena Williams, Coco Gauff, Alexander Zverev, Stefanos Tsitsipas, Naomi Osaka, Dominic Thiem, Petra Kvitova, Novak Djokovic, Rafael Nadal and Roger Federer. This brought the Aces for Bushfire Relief total to almost $5 million.[179]

In June 2020, Kyrgios publicly criticized Djokovic for organizing the controversial charity tennis tournament at which Djokovic and numerous other tennis players tested positive for Covid-19, calling it a "boneheaded decision".[180]

In January 2021, Kyrgios called Djokovic a "tool" after he issued a wish-list of requirements for players forced to quarantine when they arrive in the country to play in the Australian Open.[181] A year later, when Djokovic was detained by the Australian government after entering the country unvaccinated, Kyrgios spoke up for him, declaring: “He’s a human, I just don’t think how we’re going about it is the right way and that’s coming from someone who we’ve had run in and comments about each other, but it’s not right.” He also praised Djokovic for his generous response to the bush fire disasters.[182] [183]

In June 2022, after Djokovic beat Kyrgios in the Wimbledon final, Kyrgios called Djokovic "a bit of a god" after which Djokovic jokingly declared his relationship with Nick Kyrgios "officially a bromance".[169]

Kyrgios has been involved in numerous controversial incidents during tennis matches, including occasions when he has said disrespectful comments to, or about, his opponent, the umpire, the lines judges, ball boys/girls and members of the audience.

During a match at the 2015 Rogers Cup, Kyrgios generated considerable controversy for insults he directed at Stan Wawrinka in the middle of the match. Kyrgios, speaking aloud but not directly to Wawrinka, said: "Kokkinakis banged your girlfriend. Sorry to tell you that, mate". Microphones also picked up Kyrgios saying under his breath that Wawrinka, 30 at the time, was "banging 18-year-olds".[184] After the match, Wawrinka said he found the comments "unacceptable" and urged action be taken against Kyrgios.[185]

Kyrgios was fined $13,127 and given suspended penalties of $32,818 and a 28-day ban, pending further breaches by the ATP. He claimed he later apologised to Wawrinka[186][187] though Wawrinka denied this claim.[188] Kyrgios's mother shut down her Twitter account several hours after this incident after personal criticisms were levelled at her. She indicated that her son's insults had been made in retaliation, and that Wawrinka accused her son of "faking an injury" during a previous match between the two.[189]

Following a review, the ATP handed down a 28-day suspended sentence, to expire after six months. Kyrgios would also have received a $25,000 fine had he incurred a further fine for "verbal or physical abuse" during that six-month period.[190] At the same tournament he received a $3,281 fine for unsportsmanlike conduct for a comment he made to a ball person.[187]

Kyrgios has also been warned and fined for various other instances of inappropriate behaviour. He was given three code violations for audible obscenities and racket-smashing at the 2014 US Open (one more would have disqualified him), fined $4,926 for audible obscenities and racket-smashing at the 2015 Australian Open, fined $12,470 for unsportsmanlike conduct and $2,625 for swearing at the 2015 Wimbledon, fined $4,370 for swearing at the 2016 Australian Open (he also took a phone call while on court during a mixed doubles match), fined $6,200 for swearing at the 2016 French Open, and fined $8,690 for swearing at the 2016 Wimbledon.[187]

At the 2018 Queen's Club Championships, Kyrgios was issued a $17,500 fine after "miming masturbation with his water bottle" during a changeover in his semifinal match against Čilić.[191][192][193] At the 2019 Rome Masters, Kyrgios was defaulted from his second round encounter with Casper Ruud after swearing at a line judge, kicking a bottle, and hurling a chair onto court. Kyrgios was subsequently fined €20,000 and forfeited all prize money and points earned during the event, and told to cover the costs of his hospitality.[194][195] In June 2019, Kyrgios was assessed three fines totaling $17,500 for unsportsmanlike conduct at the 2019 Queen's Club Championships.[193]

Kyrgios was fined $113,000 for five separate incidents of unsportsmanlike conduct at the 2019 Cincinnati Masters tournament. During the second set, Kyrgios felt that the shot clock, which counts down the time allowed between points, had been started too early, and delivered an expletive-laden rant at umpire Fergus Murphy, saying Murphy was "the worst, hands down". He then walked off court, claiming he needed to use the restroom, but instead used the time to smash two racquets on the floor in a corridor. At the end of the match Kyrgios told Murphy he was "a fucking tool", did not shake his hand, made a vulgar gesture, and appeared to spit at him.[196][197] The fine set an ATP record.[198]

Kyrgios was fined $25,000 for unsportsmanlike conduct and an audible obscenity in his quarter-final match against Rafael Nadal at the 2022 Indian Wells Masters, in which Kyrgios had received a point penalty for swearing at a fan during the match, and had repeatedly clashed with the crowd and umpire Carlos Bernardes.[199] At the 2022 Miami Open, Kyrgios was fined $47,000 for unsportsmanlike conduct during his loss to Jannik Sinner. Kyrgios had again clashed with Bernardes, who had given him a point penalty and then a game penalty during the match.[200]

Kyrgios was fined $4,000 by the All England Club after his controversial match with Stefanos Tsitsipas in the third-round of the 2022 Wimbledon championships.[201] According to one source, "the entire match was heated and had several high-tension moments". Kyrgios halted play after Tsitsipas hit a backhand into the crowd, possibly hitting a fan. Kyrgios stopped play for several minutes, yelling and swearing at the umpire, claiming he should have defaulted Tstisipas. Tsitsipas criticised Kyrgios at the press conference afterwards calling him a bully.[202]

Kyrgios was fined $7,500 at the 2022 US Open, the biggest fine in the tournament's history, after yelling, and later spitting, at his player's box during his second round match against Benjamin Bonzi.[203]

At age 19, ranked 144th in the world, he received a wildcard entry to play at Wimbledon and beat then-world No. 1 Nadal in the fourth round. Beating Nadal, the first time he played against him, brought international attention. From then on he was told: "you’re the next big thing in tennis". Kyrgios admits he didn’t know how to deal with the pressure. He told the Turn Up the Talk podcast in May this year: "I kept trying, trying and trying, just ended up snowballing into this dark cloud."

Things became so difficult for him that Kyrgios posted on Instagram that in 2018 he suffered from depression and engaged in self-harm and had suicidal ideation.[204] In an interview on the Turn Up The Talk podcast, he explained that in 2019, even when he was winning tournaments: “[I was] probably drinking 20 to 30 drinks every night – you know, just in my room on my own – waking up [and] playing." Kyrgios said that "winning tournaments seemed to ‘just mask all of it’, which was the ‘darkest thing ever’."[205][206] Struggling to cope, he sought professional help and saw three or four different psychologists.[207]

Kyrgios was previously in an on-again, off-again relationship with Croatian-Australian tennis player Ajla Tomljanović.[219][220]

In 2020, he was in a relationship with Chiara Passari, breaking up in late 2021 after police had to separate the two in a hotel quarantine argument.[221][222] In July 2022, it was announced that Kyrgios was summoned to appear in court in Australia on 2 August 2022 to face a charge of common assault, for allegedly grabbing Passari, in December 2021. The incident was initially reported to police in December 2021.[223]

In May 2022, Kyrgios announced his engagement to blogger Costeen Hatzipourganis.[224][225]

Current through the 2022 US Open.
