Tallon Griekspoor defeated Ethan Quinn 4–6, 6–1, 6–7, 6–1, 6–4 in the second round of Roland Garros on clay, confirming his status as the heavy pre-match favourite. Quinn, competing as the significant underdog, mounted early resistance by taking the opening set, then pushed hard in the third to force a tiebreak, but Griekspoor's superior consistency proved decisive. The Dutchman recovered from the first-set loss to dominate the second and fourth sets with commanding performances, before closing out a five-set encounter that saw momentum swing repeatedly. Griekspoor's ability to regroup after losing the third set underlined his experience at Grand Slam level and advances him deeper into the tournament.
