According to Earley, the official said he wanted to check whether Kyrgios needed medical attention and to warn the player that Lahyani "would need to take action" if the "seeming lack of interest in the match continued".
Kyrgios turned the match around after the interaction, dropping just six more games as he triumphed, 4-6, 7-6 (8-6), 6-3, 6-0, to set up a showdown with Roger Federer in the third round.
"I'm not sure it was encouragement".
When asked afterwards about Layhani's intervention, Kyrgios said: "He was concerned about how I was playing, like, 'Nick, are you OK?' I said everything was fine, I just wasn't feeling great".
"I think he finds it hard to not do any of those tricks", the Swiss said. He said he liked me - I don't know if that's encouragement. "Sorry to say but he really should resign his position immediately", said the Australian.
"I want to help you, I want to help you", Lahyani purportedly told Kyrgios.
US Open umpire Mohamed Lahyani speaks to Nick Kyrgios during his second round match.
"I don't know yet if it would have changed something".
The second seed will take a 2-1 career lead over the combustible Kyrgios into their Sunday (AEST) duel but all three of the pair's encounters on the ATP Tour have gone to three sets. I don't care what he said.
This time, of course, Kyrgios received no sort of counsel during the match other than all the muttering, at various volumes, he directed at himself.
"The umpire doesn't need to talk to him".
Tennis remains one of those sports that prides itself on a sense of decorum, but Ozzie Nick Kyrgios has never been much bothered with all of that. He came back to beat Herbert, 4-6, 7-6 (6), 6-3, 6-0. Kyrgios dropped only one point on his serve in the last set while his groundstrokes wreaked havoc on Herbert, who was broken in each of his three service games. Mohamed, whether he came down from the chair or not, he tried to encourage him to play better, to remind him that he has a responsibility towards the fans.
"He wasn't coaching me at all". On-court microphones caught the chair umpire delivering a motivational speech - bordering on something you'd only hear from a coach - to the Aussie. This is incredible because [for the first time] in 40 years I'm actually going to defend an umpire. From I what heard, knowing Mohamed, I think he has done it in a friendly way.
"After seeing the video I am angry against the umpire".
However, the incident didn't sit well with Kyrgios's next opponent, 20-time Grand slam victor Federer, who said: "It is not the umpire's role".
"It's a conversation, and a conversation can change your mindset". "When we players are making mistakes on court we are sanctioned".
He then tweeted: "I shouldn't have tweeted so quickly after the match".
