Gael Monfils v Hugo Dellien preview

World No. 42 Gael Monfils plays the Bolivian Hugo Dellien in the first round of the French Open at Roland Garros. Monfils is now a 38-year-old veteran of the sport and has graced the ATP tour for over 20 years. Over that period, the Frenchman has amassed 13 ATP titles. However, only one of those trophies was won on a clay court, and that was in 2005 in Sopot.
Monfils started the year well, winning the ASB Classic in January before taking the scalp of Taylor Fritz in the third round at the Australian Open. Monfils gave Ben Shelton all he could handle in the fourth round and was 1-2 down in sets when he succumbed to the heat and pressure and was forced to retire. He's struggled for wins since, and illness has caused him to withdraw from some events.
31-year-old Hugo Dellien is an experienced tour pro, in his 16th year on the circuit. He's had success on the Challenger tour but is yet to capture an ATP title. Currently ranked 96 by the ATP, he's coming off a decent showing in the Skopje Challenger tournament last week, reaching the semifinal. He also survived qualifying at the Italian Open before losing to Alex de Minaur in the Round of 32.

Gael Monfils v Hugo Dellien prediction

Gael Monfils's best performance at Roland Garros was a semifinal in 2008, when he was beaten by Roger Federer. Last year, he was knocked out by Lorenzo Musetti in the second round. Hugo Dellien failed to qualify last year and was beaten in round one in 2023 by Nicolas Jarry. His best years in Paris were in 2019 and 2022, when he reached the second round.
Despite his age, Monfils is still capable of challenging at the top of the game, evidenced by his victory at the ASB Classic four months ago. If he can stay injury-free, he can progress at the French Open, and Dellien has neither the resume nor the recent form at the top level to upset the odds.
Pick: Gael Monfils to win in straight sets.
