Francisco Cerundolo is having a moment…

After entering the French Open without a main-draw win at the event, the 24-year-old Argentine professional tennis player has secured his best Grand Slam result by reaching the fourth round in Paris.

Cerundolo, the No. 23 seed, defeated ninth seed Taylor Fritz 3-6, 6-3, 6-4, 7-5 on Saturday evening to continue his run, improving to 6-7 against Top 10 opponents with the victory.

Cerundolo was without a win in four Grand Slam main-draw appearances prior to 2023, but reached the third round at the Australian Open before his success at Roland Garros.

His Paris campaign will continue with a showdown against sixth seed Holger Rune on Monday.

Cerundolo, who has moved up three places from his current career-high to No. 20 this week in the ATP Live Rankings, frustrated Fritz with his big forehand to earn the victory on Court Suzanne-Lenglen after two hours and 50 minutes.

After surrendering an early break advantage in a dramatic fourth set, Cerundolo saved a set point on serve at 4-5 with a majestic topspin lob and ultimately won the final three games of the match behind his baseline brilliance.

The back-and-forth match saw a combined 10 breaks of serve, with Cerundolo converting on six of 21 break chances and Fritz claiming four of his 15 break points. Fritz, whose defeat means that five of the Top 10 seeds are out after three rounds at Roland Garros, fired nine aces to Cerundolo’s one. But the American was second-best in many of the neutral rallies as Cerundolo moved him from side to side with power and width.

Cerundolo, a quarterfinalist at the ATP Masters 1000s in Miami and Rome this season, was one of three Argentines in action on Saturday. While Rune breezed past Genaro Alberto Olivieri, Tomas Martin Etcheverry upset 15th seed Borna Coric 6-3, 7-6(5), 6-2 earlier in the day. With the victory, the 23-year-old Etcheverry — who reached his first two ATP Tour finals this season in Santiago and Houston — extended his best major run.

Etcheverry owned just one Grand Slam main-draw win prior to Roland Garros, his victory coming earlier this season at the Australian Open.

Next up for the unseeded Argentine is a fourth-round meeting with 27th seed Yoshihito Nishioka, a 3-6, 7-6(8), 2-6, 6-4, 6-0 winner against Brazilian qualifier Thiago Seyboth Wild on Saturday.
