The erratic Kyrgios lost the opener 6-4 and was trailing 0-3 in the second set when Lahyani left his chair at the changeover and told the Australian: "I want to help you".
Spectators on Court 17 of the on-going US Open witnessed a rather unusual interaction with the umpire of the game Mohamed Lahyani and Nick Kyrgios who seemed to be struggling against Frenchman Pierre-Hugues Herbert. He asked about Kyrgios's health.
"Actually, the umpire doesn't have to talk to him at all".
A brief recording captured the conversation between Lahyani and Kyrgios, ESPN reported.
As he posted a farewell message to NY on Instagram, Murray added: "I'm off to get a health check as apparently I've started imagining things".
"I mean, like, I don't have a coach".
Kyrgios maintains there was no "coaching" involved, while the USTA has since cleared Lahyani of any major wrongdoing, saying the Swede went "beyond protocol" but will continue to umpire at the tournament.
Australian Open champion Wozniacki went down 6-4, 6-2 to world number 36 Tsurenko who claimed a second top 10 win this month having also defeated Garbine Muguruza in Cincinnati.
Richard Ings, a former umpires chief on the ATP, said Lahyani's move was unprecedented. He added: "Nick, I know this is not you". "I don't think he's a coach, he's an umpire". I'm not sure if that was encouragement.
"I don't know what he said". He was there for too long.
However, Lahyani, a well-experienced umpire on men's ATP Tour and Grand Slam circuit, escaped any sanction and will be allowed to continue officiating at Flushing Meadows because of his "exemplary track record as an global tennis official", a United States Tennis Association spokesman said. "I had no real choice". "He behaves the way he behaves", said the 20-time major victor. Lahyani appeared to have thought Kyrgios wasn't giving 100 percent in his match, which the tennis player had admitted to in the past.
Lahyani told Kyrgios things like, "I want to help you, I want to help you". He said he didn't blame Kyrgios and instead cut loose at the umpire and the USTA for how it handled the matter. "Haha IRONIC coming from someone who gets on court coaching every week of the year and also out of the US Open", he responded. It was not just about, 'How are you feeling?' 'Oh, I'm not feeling so well.' Go back up to the chair. Many believe if he could put it all together and just commit to the game, he'd be one of the best players on the planet.
"The umpire should have given Nick Kyrgios a warning for unsportsmanlike behaviour because he's not trying and it's bad for the sport but in no chance can the chair umpire go down and have a sort of psychology session with one of the players".
"It's a conversation, and a conversation can change your mindset". But after last year's first-round dismissal, the German most definitely has her sights set on a two-week stay this year.
