British number one Kyle Edmund reached the French Open second round for the fourth successive year with an opening win against Australian Alex de Minaur.
Edmund, who is seeded at a Grand Slam for the first time, won 6-4 6-2 6-3 at Roland Garros.
De Minaur, 19, is considered a rising star of Australian tennis, but could not cope with 16th seed Edmund's accuracy and power.
The Briton will play Hungary's Marton Fucsovics in the second round.
Fucsovics, ranked 45th in the world, progressed with a 6-3 6-3 7-6 (7-5) victory over Canada's Vasek Pospisil.
