SHANGHAI • Nick Kyrgios said he was "bored" during his straight-sets win over Sam Querrey as he extended his hot run of form at the Shanghai Masters yesterday.
The outspoken Australian, who lifted the Japan Open trophy on Sunday, won 6-4, 6-4 in just 53 minutes as he cantered past the American and into round two of the tournament.
Afterwards Kyrgios, who is at a career-high 12th in the rankings and eyeing the top 10, suggested he was not at his best so soon after his long week in Tokyo.
"I was just a little bit bored at times," he said, when asked why he was not his usual vocal self on court against the world No. 29.
"I was feeling very tired today. I didn't have the greatest sleep last night and obviously got in late the day before, and the ride to the courts isn't great either.
"It was just tough. I'm just tired today, so maybe I just wanted to get the job done."
The Shanghai Masters, held at the Qi Zhong Stadium located one hour from the city centre, is perhaps not a favourite tournament for Australia's No. 1.
Last year he was slapped with a US$1,500 (S$2,070) fine for an audible obscenity in a tirade in which he slammed the event as a "circus" and complained about the ball kids, according to reports.
However, Kyrgios now presents a more focused figure after teaming with British strength and conditioning expert Martin Skinner in recent weeks.
"I just trust him," the 21-year-old said of Skinner. "He tells me what to do and I do it. I think that's one thing I've improved on the most, the off-court stuff."
Yesterday's win was the sixth straight for Kyrgios. He has won all three of his ATP titles this year and is in line to become Australia's first top 10 player since Lleyton Hewitt in 2006.
"It's not easy for anyone, I think, to win a tournament and come back and beat a quality opponent like Sam," Kyrgios said. "I'm pretty pleased with the way I backed it up."
In another match yesterday, Juan Martin del Potro's late-season resurgence came crashing to a halt when he was dumped out of the first round by David Goffin.
The Argentinian wild card faded after taking the first set against the Belgian who won 4-6, 6-3, 7-5.
World No. 1 Novak Djokovic defeated Fabio Fognini 6-3, 6-3 in the second round.
