MONTE CARLO, April 9 — World no.11 Alex de Minaur made up for lost time at the Monte Carlo Masters with a 62-minute straight sets win over Stan Wawrinka in a match that was delayed for two and a half hours because of rain.

The 39-year-old wild card Wawrinka, formerly ranked no.3 in the world but now down to no.79, was no match in the first round for the Australian who prevailed 6-3, 6-0 on the main Rainier III court.
