Kyrgios crashes out to fellow Aussie in New York
NICK Kyrgios admits he is not dedicated to the game at all after crashing out of the US Open to fellow Australian John Millman in New York.
Kyrgios' miserable grand slam season was completed with a 6-3 1-6 6-4 6-1 defeat to Millman in the first round.
The world No.17 complained of a "dead" shoulder during the loss and after the defeat gave a damning verdict of where his career is at.
Asked if he would continue working with Frenchman Sebastien Grosjean beyond the Open, Kyrgios said: "I don't know, honestly. I'm not good enough for him.
"He's very dedicated. He's an unbelievable coach. He probably deserves a player that is probably more dedicated to the game than I am. He deserves a better athlete than me.
"I'm not dedicated to the game at all.
"He's helped me a lot, especially with the training, in training sessions, but there are players out there that are more dedicated, that want to get better, that strive to get better every day, (do the) the one-percenters. I'm not that guy."
Kyrgios said his latest shoulder problem, which first emerged early in the third set against Millman, came out of the blue.
"I have had a diabolical year at these slams. It doesn't surprise me," he said.
"It's just the story of my career, really. I will have good weeks; I'll have bad weeks. It's just a rollercoaster."
Kyrgios had had a decent build-up to the final major of the year, defeating world No.1 Rafael Nadal before reaching his first Masters 1000 final in Cincinnati.
But this week it has not been all champagane and roses for the Canberran.
"In Cincinnati, I was not doing anything different. I was probably less dedicated than I was this week," Kyrgios said.
"I was playing basketball at Lifetime Fitness every day for two hours. Like I played an hour of basketball before I played David Ferrer in the semi-final.
"I was going to ice cream, like this Graeter's place getting a milkshake every day. I was less dedicated.
"And this week I was dedicated, and my shoulder starts hurting. I don't know."
Despite his disappointment and new shoulder problem Kyrgios said he was still planning to help Australia into battle against Belgium in the Davis Cup semi-finals this month in Brussels.
"I wasn't feeling it at all and then on one serve I lost power in my arm. Just on my serve," Kyrgios said of his shoulder injury.
"One serve, then completely dead. It's so dead and numb. It's incredibly weak. It's just so annoying."
