Jack Draper bullied Brazilian Joao Fonseca out of the French Open to stay on collision course to meet Jannik Sinner in the last eight. Teenager Fonseca has been tipped as a future superstar – and Mats Wilander claimed before the match that the world No.65 could join the Italian and Carlos Alcaraz in a new Big Three.

But the future did not arrive on Court Suzanne-Lenglen today as Draper, 23, gave the 18-year-old a tennis schooling. Foneseca has a fearsome but wild forehand and the rest of his young game has still to mature. Draper mixed drop shots – which his opponent usually did not chase – with looping groundstrokes to break his rhythm and his spirit. And long before the end the flummoxed Flamengo fan was looking up to his player box in confusion as Draper won 6-2 6-4 6-2 in one hour and 46 minutes.

The hyped encounter started in gentle drizzle and ended as a damp squib. Draper has now beaten Fonseca twice without dropping a set. It was man against boy.

The British No.1 will next face the winner of the third round clash between world No.62 Alexander Bublik – who knocked out the seeded Alex de Minaur – and world No.200 Henrique Rocha.

World No.1 Sinner is Draper’s seeded quarter-final opponent. And the Italian looked in awesome form as he needed only 94 minutes to dispatch Jiri Lehecka 6-0 6-1 6-2 .

Draper was given a boost before the start when French No.1 Arthur Fils pulled out of the tournament with a back injury and this match was upgraded from Court Simonne-Mathieu where ground-pass holders can watch. This would have seen a larger and noisier support for Fonseca. There were still Brazilian flags and football shirts in the Court Suzanne-Lenglen – and there were outbreaks of cheering and singing for Fonseca winners.

But the British No.1 took early control of the match and never let up the pressure.

Draper broke in the third game when the weight of his groundstrokes forced Fonseca to hit a forehand long.

At 2-4, the Brazilian’s wild forehand gifted another three break points and the world No.5 took the first with a forehand winner down the line. He took his second set point in the next game when Fonseca’s backhand hit the net after 29 minutes.

The second set followed a similar pattern. At 3-3, Draper took his second break point when he returned one huge Fonseca forehand and the second crashed into the net.

Serving for the set at 5-4, Draper saved a first break point when the Brazilian blazed another big forehand just over the baseline and another with an ace. It was to be a big hold.

And he took his first set point when Fonseca slapped a horrible forehand into the net after 71 minutes.

Both players took breaks after the second set but the momentum of the match continued. In the first game of the third set, Draper took his third break point when a framed Fonseca forehand ended in the crowd. And the second break of the set came when Fonseca’s backhand slice went long. He saved two break points at 0-4 and played two successful drops as he served to day in the match at 1-5 before Draper took his first match point when Fonseca’s backhand return hit the net.

Draper said: “Joao is new to the Tour and he has caught the attention of everyone – fans and the players. He is an incredible player. There is so much to come from him. Today I think it was experience. I don’t think he has played as many Grand Slams as me.

“I played well. The conditions were quite good. My first two rounds were at nighttime. Against Gael (Monfils) it was difficult to get the ball past him. Today the ball was getting up more. My game suits the fast conditions.

“I think the first set was really key. I got on top of him. I used my forehand very well. I am just happy to be in the second week.”
