Gaël Monfils suffered immense disillusion by eliminating in the first round of Roland-Garros on Monday.

Rafael Nadal and Dominic Thiem did not have any problem for their entry into contention at Roland Garros, unlike Serena Williams, who had to fight.

The best-ranked Frenchman at ATP has already been eliminated from Roland-Garros.

Gaël Monfils, current 9th in the world, was beaten at the outset by Kazakh Bublik in four sets (6-4, 7-5, 3-6, 6-3), on Monday Porte d'Auteuil.

The "Monf", in total loss of confidence for several weeks, had not been eliminated in the first round of Roland-Garros since 2005.

The favorites entered on Monday have, on the contrary, not trembled.

The defending champion Rafael Nadal easily dismissed Belarusian Gerasimov in the first round, in three sets and just over 2 hours of play (6-4, 6-4, 6-2).

Dominic Thiem, finalist of the last edition and recent winner of the US Open, did not fall into the trap of Croatian Marin Cilic (also winner of the US Open, in 2014), by winning in three sets (6-4, 6-3, 6-3).

Serena Williams, for her part, suffered in her first set against her compatriot Kristie Ahn, before unfolding in the second round (7-6, 6-0).

Great first for Hugo Gaston, Moutet beaten after a 6h fight

Still on the side of the French, the young Hugo Gaston, 20, won his first Grand Slam victory by beating his compatriot Maxime Janvier (7-6 [5], 6-4, 6-3).

Pierre-Hugues Herbert, 78th in the world, had no trouble getting rid of the American Michael Mmoh, 177th in the world (6-3, 6-2, 6-3) and will challenge the German Alexander Zverev in the next round, finalist of the last US Open.

Corentin Moutet suffered a cruel defeat against the Italian Lorenzo Giustino, after an incredible marathon of more than 6 hours (0-6, 7-6 [7], 7-6 [3], 2-6, 18-16 ).

The Frenchman, who served for the match in the decisive round, can harbor great regrets.
