Korda failed to build on an early break as Alcaraz took the opener on Court Philippe-Chatrier, but he appeared to have the Spaniard on the ropes when he forced a second-set tie-break.

However, the two-time grand slam champion clinched the tie-break with a huge forehand winner and seemed to grow in stature from there, moving well and displaying too much power for his American opponent.

Alcaraz put Korda under pressure from the off in the third set and did not give up a single break point on his own serve, converting the first of two match points with a neat serve and volley.

He will face either Ben Shelton or Felix Auger-Aliassime next, with Stefanos Tsitsipas potentially lurking in the quarter-finals.

As was the case against Jesper de Jong in round two, Alcaraz looked to be under serious pressure against Korda, only to step things up and pull away from his opponent.

He has now won 14 of his 17 singles matches at the French Open, with his win ratio of 82.4 per cent the third highest among active male players, after Rafael Nadal (96.6 per cent) and Novak Djokovic (85.3 per cent).
