Britain’s Alfie Hewett began his Wimbledon title defence with a comfortable victory against Spain’s Daniel Caverzaschi in 54 minutes.
A 10-time major champion in singles as well as a 22-time champion in doubles alongside compatriot Gordon Reid, Hewett secured a comprehensive 6-1 6-2 win on court three.
The 27-year-old finally clinched a maiden title at SW19 last year to complete a career Grand Slam.
The second seed will face China’s Ji Zhenxu in the quarter-finals and cannot meet doubles partner Reid until the final.
Hewett and Reid will get their campaign for a third consecutive doubles title under way on Wednesday.
Meanwhile, British wildcard Dahnon Ward lost his first-round match against Spanish third seed Martin de la Puente 6-2 6-0.
