Kyrgios storms into second round

London - Wimbledon giant-killer Nick Kyrgios made a triumphant return to the All England Club with a 6-0, 6-2, 7-6 (8/6) first round demolition of Argentina's Diego Schwartzman on Monday.

Kyrgios was back at Wimbledon 12 months after he stunned Rafael Nadal in a memorable fourth round upset on Centre Court that made him the lowest ranked player to beat a world number one at a Grand Slam for 22 years.

The brash 20-year-old, who eventually bowed out in the quarter-finals last year, followed that breakthrough performance by becoming the first teenager since 1990 to reach the Australian Open quarter-finals.

"I've had a bit of a sinus infection and haven't played much, but I'm getting better," Kyrgios said.

"I started unbelievably and hardly missed a ball in the first two sets. I'm feeling confident."

Canberra-born Kyrgios, already renowned for his flamboyant style on and off court, endured the first difficult period of his career in the build-up to Wimbledon.

A lingering virus contributed to his 47-minute defeat against Stan Wawrinka at Queen's Club and Kyrgios, weary from spending several months on the road, responded by withdrawing from a tournament in Nottingham and complaining that he wanted to forget about tennis for a while.

Then, just days before his Wimbledon opener, the world number 29 split with long-time coach Todd Larkham.

Returning to the scene of his giant-killing exploits seemed to put a spring in Kyrgios's step however and, after striding onto Court Two with a pair of bright pink headphones clamped to his ears, he swept through the first set in just 17 minutes.

Schwartzman, the world number 63, was playing only the second grass-court match of his career and Kyrgios ruthlessly exploited his lack of experience to seal the emphatic win in 85 minutes.
