Shanghai (AFP) - Australia's 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 on Tuesday.
The outspoken 21-year-old, who lifted the Japan Open trophy on Sunday, won 6-4, 6-4 in just 53 minutes as he cantered past the American world No. 29 and into round two.
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. "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."
