Matteo Arnaldi's remarkable run at Roland Garros continued on Wednesday as the unseeded Italian advanced to his first Grand Slam semifinal, setting up a historic showdown with fellow countryman Flavio Cobolli.
Arnaldi booked his place in the last four after Matteo Berrettini was forced to retire with a left hip injury while trailing 7-5, 5-2 in their quarterfinal match.
The result marked a significant milestone for the 24-year-old, who arrived in Paris ranked No. 104 in the world and had never previously progressed beyond the third round of a Grand Slam. His impressive campaign is now expected to propel him to a career-high ranking of No. 34 when the ATP rankings are updated.
Despite securing the biggest result of his career, Arnaldi's celebrations were tempered by the circumstances surrounding the victory.
"It's a tough one," Arnaldi said after the match. "You never want to see someone finish a tournament like this."
Berrettini had battled through physical issues throughout the event, but the injury ultimately proved too much to overcome after more than two hours on court.
Arnaldi's place in the semifinals caps one of the most demanding routes to the final four in recent Grand Slam history.
Before the quarterfinal, the Italian had already spent 17 hours and 42 minutes on court, the longest recorded journey to a men's singles quarterfinal at a Grand Slam since the ATP began tracking match times in 1991. His path included two four-set victories and two grueling five-set battles, showcasing both his endurance and determination.
The heavy workload has left Arnaldi feeling the physical effects, but the Italian admitted he is simply grateful to be competing at such a high level after overcoming injury setbacks earlier in the season.
Now, his reward is a place in an all-Italian semifinal against Cobolli, guaranteeing Italy a representative in the Roland Garros final.
The matchup also highlights the growing strength of Italian men's tennis, with a new generation of players continuing to make their mark on the sport's biggest stages.
For Arnaldi, however, the focus remains firmly on extending a breakthrough run that has already transformed his career. After arriving in Paris as an outsider, he now stands just one win away from reaching his first Grand Slam final.
