Alex de Minaur was not at his very best but still had too much quality for British qualifier Toby Samuel as he launched his French Open bid with a straight-sets stroll in the Paris sunshine.
But while Australia's top hope and a rejuvenated Daria Kasatkina powered through to the second round on a sweltering Monday at Roland Garros, teenager Emerson Jones found the going rather too hot as she was given an hour-long lesson on Court Philippe Chatrier by the four-time champion Iga Swiatek.
De Minaur reckoned he had rediscovered his focus and confidence at the Hamburg Open last week after a clay-court slump in which he'd suffered three early tournament exits.
And buoyed by stepping onto the sun-baked Roland Garros courts, he outplayed British main draw debutant Toby Samuel 6-4 6-4 6-2.
