Making his first-ever career third-round appearance at any grand slam, World No. 49 Tomas Martin Etcheverry took down 15th seed Borna Coric with a 6-3, 7-6(5), 6-3 victory after three hours on Saturday afternoon in Paris.
Etcheverry, who did not drop a set on his way to the round of 16, will face 27th seed Yoshihito Nishioka for a place in the quarterfinals.
The Japanese player survived a five-set battle across three hours and 38 minutes on Court Simonne-Mathieu against Brazilian Thiago Seyboth Wild, who ousted World No. 2 Daniil Medvedev earlier in the week.
The edgy three-setter clash between Etcheverry and Coric, decided by small margins, featured breathtaking extended baseline exchanges in which both showcased exceptional form.
The La Plata born-player hit first, breaking in the second game to never look back, notching a 6-3 win in only 36 minutes.
The Argentine made the difference behind his serve, winning 92 percent of the first serve points and 80 percent of his second.
In the second set, Coric, 26, fought back from 3-5 down, breaking in the 10th game and holding to earn a crucial lead at 6-5.
Ultimately, the second set unfolded into a balanced tiebreaker which the 23-year-old sealed 7-6(5) in 89 minutes over the Croatian.
Etcheverry held his nerve, stepping up the pressure to dominate the third set, breaking three times on his way to a 6-2 win to wrap up the match.
In the final set, the sixth game would become an inflection point in the development of the match.
Coric dropped his serve after recovering from 0-40 down to 40-40, as he hit a double fault that would cost him high.
Walter Grinovero’s pupil, who in 2023 moved through the finals in Santiago and Huston, finished with 30 winners (4 aces) to 34 unforced errors compared to his rival 26 to 42.
In addition, he won 80 percent of the first serve points, converting five of 17 breakpoint opportunities and winning 16 of 19 net approaches.
En route to the fourth round, he prevailed over Briton Jack Draper in his first rounder as the latter retired at 6-4, 1-0.
On Thursday, he triumphed over 18th seed Alex de Minaur 6-3, 7-6(2), 6-3, recording his first career Top 20 win, setting a meeting with Coric.
World No. 33 Nishioka and Etcheverry never faced one another at tour level.
