Alex de Minaur could not be deflected by either rain showers or a determined compatriot as he began his assault on Wimbledon's grass citadel with a straight sets victory.
James Duckworth provided obdurate opposition, but despite forcing a trio of tie-breaks, Australia's No.8 could not take a set off the national No.1.
With his Davis Cup captain Lleyton Hewitt watching on, de Minaur won 7-6 (7-1) 7-6 (7-3) 7-6 (7-4).
