French Open champion Stan Wawrinka began his grass-court season with a convincing win over Australia's Nick Kyrgios at Queen's Club.
The 30-year-old Swiss, playing his first match since winning at Roland Garros, won 6-3 6-4 to reach round two of the Aegon Championships.
"I'm happy with the way I'm playing already," Wawrinka told BBC Sport.
