In April, riding the momentum of a ten-match winning streak, Gasquet reached the semifinals of the Masters Series tournament at Monte Carlo, handing world No.

Fresh off of Gasquet’s win over Federer and having just beaten Paradorn Srichaphan in straight sets, the rising teen disappointingly lost against Andre Agassi in Rome.

On 18 June, his 19th birthday, he won his first ATP Tour singles title beating Max Mirnyi in the final of the Nottingham Open in England on grass.

After defeating Nick Lindahl, Feliciano López, and Igor Andreev, Gasquet lost in four sets in the fourth round of the Australian Open to eventual finalist Jo-Wilfried Tsonga.

At Gasquet’s next two tournaments, the Open 13 at Marseille, France, and Barclays Dubai Tennis Championships, he suffered second-round defeats to Robin Söderling and Igor Andreev.

Gasquet teamed up with Michaël Llodra (who replaced Monfils) to play the doubles rubber on day two, but they lost in four sets against Radek Štěpánek and Tomáš Berdych.

In April, he played at the Grand Prix Hassan II tournament, where he defeated Olivier Rochus and Andrey Golubev, before losing to Victor Hănescu in the quarterfinals.

Gasquet defeated Olivier Rochus and Andreas Seppi in the Serbian Open, but lost to John Isner despite being two points away from victory and a break up in the final set.

Gasquet then played in the Aegon Championships in preparation for Wimbledon, and won against Kei Nishikori and Rajeev Ram, but withdrew in the third round due to a back injury.

He reached the third rounds of the Rogers Cup in Canada and the Southern & Western Open in Cincinnati, where he was defeated by Nicolás Almagro and Mardy Fish, respectively.

He competed in the Australian Open shortly afterward, defeating Andreas Seppi, Andrey Golubev, and ninth seed Janko Tipsarević en route to the fourth round.

He had more success in the doubles, however, as he and Julien Benneteau defeated Spaniards David Ferrer and Feliciano López in the third-place playoff to win the bronze medals.

As the ninth seed, Gasquet reached the third round at the 2013 Wimbledon Championships where he lost to Bernard Tomic in four sets,[33] despite winning 13 more points than his Australian opponent.

Nevertheless, Gasquet's run strengthened his grip on a top-10 position, and he went on to reach the World Tour Finals for the second time in his career, once again being eliminated in the group stage after defeats by Juan Martín del Potro and Roger Federer.

Gasquet suffered further misery in the second round at Wimbledon, when he once again relinquished a two-set lead, this time to wild-card Nick Kyrgios, losing a joint Grand Slam record nine match points in the process.

Gasquet returned to Montpellier to win his 11th ATP Tour singles title at the Open Sud de France, after his victory in the final over the injured Jerzy Janowicz.

After playing in the 2020 Open 13, and the 2020 Dubai Tennis Championships, (where he reached the quarterfinal), Gasquet's season was paused due to the Covid-19 pandemic and subsequent shutdown of the ATP Tour.

[5] At the 2023 Wimbledon Championships he recorded his 71st Grand Slam participation tied with Novak Djokovic and Fernando Verdasco, and only behind Roger Federer and Feliciano Lopez, and his 72nd at the US Open.

At the 2024 ASB Classic where Gasquet was the defending champion, he lost to teenager and fellow compatriot Arthur Fils which ended his 956 weeks in the top 100, the longest active streak since April 2005.

At the 2024 Țiriac Open Gasquet was supposed to play his 1000th career match against Federico Coria joining active players Djokovic, Nadal and Verdasco in accomplishing this feat, but withdrew late from the tournament, having received a wildcard for the main draw.

Gasquet’s backhand is known for its consistency, speed and accuracy, and has been acclaimed by many past players and commentators such as Robbie Koenig, John McEnroe and Brad Gilbert.

His volleys are consistent and he very actively seeks to end points at the net, which complements his baseline ability to push players to the back of the court, buying him time to come up.
