Live: Roland Garros 2026 — Follow João Fonseca vs. Jakub Mensik in the Quarterfinals

João Fonseca and Jakub Mensik have already met once in their careers, giving their next matchup an added layer of intrigue. The only previous encounter between the two came in December 2024 during the group stage of the Next Gen ATP Finals, the tournament that brings together the best young players in men’s tennis.

Their match was a tight, high-quality battle played under the event’s unique format, with sets decided by the first player to reach four games. Fonseca came out on top after a dramatic contest that went all the way to five tie-breaks. The Brazilian won by narrow margins in a match marked by constant momentum shifts and very little separation between the two players.

The final score reflected just how evenly matched they were: 3/4 (4-7), 4/3 (10-8), 4/3 (7-5), 3/4 (4-7) and 4/3 (7-5). Fonseca’s ability to stay composed in the biggest moments proved decisive, especially in the closing stages of the match, where he held his nerve to secure the win.

That victory was part of a memorable run for Fonseca in Milan, where he went on to capture the title of the Next Gen ATP Finals. By winning the tournament, he became the first South American player ever to claim the championship, a milestone that added historic significance to his breakthrough on the ATP stage.

The result also showed the competitiveness of both players at the top level of the sport’s next generation. Mensik pushed Fonseca to the limit, and their only previous meeting suggests that any future clash between them could be just as close. Their December 2024 showdown remains an important reference point in their rivalry, highlighting the strength, poise and potential of two of tennis’s most promising young talents.
