Kyrgios: 'Not many balls can get past me'

MELBOURNE—Nick Kyrgios, who has reached the third round of the Australian Open, said he got much faster during the off-season.

The 20-year-old Aussie beat Pablo Cuevas in the second round and will next face No. 6 seed Tomas Berdych, whom he has never played.

Last year Kyrgios reached the quarterfinals in Melbourne before losing to Andy Murray.

“I feel that's the biggest part of my game that's improved from last year,” Kyrgios said. “I feel as if when I'm in the back of the court in a rally, there's not many balls that can get past me. I feel really confident moving. For me, that helps my game so much.

"Doesn't feel like I have to be so aggressive, like I have to force so much. I can sort of sit back and rally.”
