Nick Kyrgios admitted “emotions got the better of me” after forfeiting his second-round match with Norwegian Casper Ruud at the Italian Open.

The Australian, 24, was in the deciding set when he was given a game penalty, reportedly for swearing, to trail 2-1.

He then kicked a bottle, threw down his racquet, hurled a chair on the court, picked up his bag and walked off.

Kyrgios was fined 20,000 euros (£17,461) for unsportsmanlike conduct and also lost his prize money.

In addition to the prize money of £29,366, he forfeited the 45 ranking points gained during the tournament and was told to cover the costs of his hospitality.

Writing on Instagram, he said: “Very eventful day to say to the least. Emotions got the better of me and I just wanted to say that the atmosphere was crazy out there today, just super unfortunate that it had to end in a default.

“Sorry Roma, see you again, maybe.”

Kyrgios has a history of fines for poor behaviour on court and in March clashed with a fan at the Miami Open.

Earlier this week he served underarm during victory over Daniil Medvedev, while his actions on Thursday came as it emerged he told a podcast interview that he “could not stand” Novak Djokovic – who he described as “cringeworthy” – and called Rafael Nadal “super salty”.

In the 50-minute interview, Kyrgios, who last year said he was talking to psychologists to address mental health issues, was asked about his opinion on a number of tennis stars.

After branding Roger Federer the “greatest of all time”, he went in on Nadal, calling the Spaniard his “polar opposite”.

But he had nicer things to say about Britain’s Andy Murray, currently out of the game following hip surgery.

“It sucks not seeing him around here, in the locker room he was the best,” he said.

‘He deserves a ban’ – what the players said

Norwegian Ruud said he thought Kyrgios had “got what he deserved,” when asked about the mater later.

However, he believes the ATP, which governs men’s tennis, should now take action.

“He thinks he can do what he likes,” Ruud added.

“He was getting more and more angry. There’s been a lot of talk about it with other players.

“I think there should be some hard punishment, there’s been some other stuff as well. He should be suspended for at least six months.”

But 20-time Grand Slam winner Federer, did not think a suspension was warranted: “He walked off the court. What did he do? He hurt a chair? I mean, that’s not enough for me.

“A zero pointer, fine, all this stuff is already tough enough. He knows it’s a mistake what happened.”

Kyrgios’ past controversies

• In 2015, having already been fined for an “insulting remark” to opponent Stan Wawrinka, Kyrgios was given a suspended 28-day ban and £16,200 fine for making lewd remarks about the Swiss player’s girlfriend.
• The following year he was banned for eight tournament weeks and fined £20,560 for his behaviour – including “lack of best efforts” at the Shanghai Masters. During the match in question against Mischa Zverev, Kyrgios also argued with a fan and received a code violation for swearing, after which he was fined for breaching the ATP code of conduct.
• In the same tournament the next year, having earlier received a warning for smashing two balls out of court in frustration, he stormed off midway through his first-round match against Steve Johnson. He was later fined for unsportsmanlike conduct.
• The Shanghai Masters was again the venue last year when he was involved in a prolonged argument with French umpire Damien Dumusois during his first-round exit.

Analysis

BBC Tennis correspondent Russell Fuller:

The Australian will be one of the most talked-about people at Roland Garros when the French Open gets under way in 10 days’ time. But not because he is thought to have a chance of winning.

Kyrgios is an entertainer, both with a racquet in his hand and when airing his unfiltered views on a podcast, but regularly laments his lack of conditioning.

He is happy to admit he plays too much basketball.

And he knows a coach would probably be a very good idea, but prefers the freedom of only having to answer to himself.

Britain’s wheelchair tennis players can claim their best ever medal haul at the 2019 BNP Paribas World Team Cup after all four teams reached the semi-finals.

The annual tournament is the wheelchair tennis equivalent of the Fed Cup and Davis Cup competitions.

Britain’s men face Japan on Friday for a place in Saturday’s final, while the juniors meet Australia in their final on Friday.

The women’s and quads teams play South Africa for bronze medals on Friday.

Great Britain is the only country to have teams in the semi-finals across all four events at the tournament in Ramat Hasharon, Israel.

It could also be the first time that all four British teams win medals – a feat only ever achieved before by the Netherlands and the USA.

Britain’s previous best total was three medals won in 2012.

The men’s team – Alfie Hewett, Gordon Reid and Dermot Bailey – will face Argentina or France in the final if they beat Japan.

“There have been some really good performances from everyone in the team this week,” Hewett said.

British number two Andy Cotterill will be part of the quads team looking to win bronze on Friday. “We are still playing for a medal but we came here to win gold. Hopefully we can bounce back and take bronze,” he said.

British number one Johanna Konta reached the Italian Open quarter-finals with a 6-2 6-4 win over Venus Williams – her second match of the day.

Konta, 27, came from a set down to beat world number eight Sloane Stephens before overcoming seven-time Grand Slam winner Williams, now ranked 50th.

Williams was hampered by injury and an assured Konta won in 72 minutes.

She will play Marketa Vondrousova in the last eight in Rome after the Czech beat Russian Daria Kasatkina.

Having come from a set down to beat world number two Simona Halep earlier in the day, 19-year-old left-hander Vondrousova was again taken to three sets against Kasatkina, recording a 7-5 2-6 6-2 win in two hours and 13 minutes.

Williams received a walkover into the third round after sister Serena withdrew because of a knee injury.

The 38-year-old had won her past three meetings with Konta, including the 2017 Wimbledon semi-final.

She had her right knee strapped in Thursday’s contest and, although she improved as the match wore on, Konta reached the first Premier clay-court quarter-final of her career.

World number one Naomi Osaka recorded consecutive 6-3 6-3 wins over Dominika Cibulkova and Mihaela Buzarnescu to set up a last-eight meeting with world number four Kiki Bertens.

Former French Open and Wimbledon champion Garbine Muguruza withdrew from her match against Victoria Azarenka with a thigh injury when 6-4 3-1 down.

World number three Roger Federer saved two break points in defeating 13th seed Borna Coric 2-6 6-4 7-6 (9-7) to reach the quarter-finals of the Italian Open.

Federer, playing in the event for the first time since 2016, beat Joao Sousa in straight sets earlier in the day.

Coric, 22, had not played since beating Cameron Norrie on Tuesday and returned superbly to race 4-0 ahead but Federer, 37, won in two hours, 31 minutes.

There were comfortable wins for Rafael Nadal and Novak Djokovic.

It was the first meeting on clay between Federer and Coric, with the Swiss leading 3-2 on previous encounters, having won the most recent 6-2 6-2 in Dubai this year.

Having lost the opening set comprehensively, during which he was treated for a blister, Federer had his first break point opportunity at 3-2 up in the second.

Though it was not taken, a magnificent cross-court forehand created another which led to a succession of exchanges of serve, culminating in another break from Federer to seal the set in 47 minutes.

The Swiss maestro saved a break point in both the fifth and nine games of the decider but a rare wayward forehand saw him slip 3-1 behind in the tie-break.

To tumultuous cheers from the crowd in the late evening, Federer, four times a beaten finalist in the tournament, rallied and served out for victory on his second match point.

He will next face eighth-seed Stefanos Tsitsipas or Italian Fabio Fognini.

Defending champion Nadal, seeking his ninth Italian title, conceded only two games in winning his two matches on Thursday.

The 32-year-old Spaniard, who has lost in the semi-finals of his last four events, took one hour eight minutes to beat France’s Jeremy Chardy 6-0 6-1 and six minutes fewer to see off Nikoloz Basilashvili of Georgia 6-1 6-0.

Nadal next plays fellow Spaniard Fernando Verdasco, who defeated 11th-seeded Russian Karen Khachanov 7-5 3-6 6-3.

World number one Djokovic, having beaten 20-year-old Denis Shapovalov 6-1 6-3 earlier in the day, needed only an hour and three minutes to oust German Philipp Kohlschreiber 6-3 6-0.

The 31-year-old Serb, who won the last of his four Italian titles in 2015, next plays seventh seed Juan Martin del Potro, who saw off Casper Ruud – the Norwegian who had progressed after Nick Kyrgios forfeited their second-round match – 6-4 6-4.
