Nuno Borges past Jan-Lennard Struff into the Mallorca quarterfinals: calmer set finishes proved decisive in the round of 16
Nuno Borges continued a successful week on grass in Mallorca with a victory over Jan-Lennard Struff in the round of 16 of the ATP Mallorca Championships 2026. The Portuguese tennis player defeated the German veteran 6:4, 7:5 and secured a quarterfinal place at the tournament played on the grass courts of the Mallorca Country Club in Santa Ponça. According to the official ATP Tour results, the match was played on the Grandstand court and lasted 1 hour, 21 minutes and 13 seconds, with Pablo Rodriguez as the chair umpire. The result confirms the short but substantial pattern of the contest: Borges did not have to dominate the entire match, but he was more stable in the closing stages of both sets, precisely in the periods in which the course of a match on grass is most often decided.
The victory is important for Borges also because of the way it came. Struff played in Mallorca with a wildcard from the organizers, but his experience on fast surfaces and powerful serve make him an uncomfortable opponent in such conditions. The German player tried to shorten the points, look for pressure with the first shot after the serve and impose a rhythm that suits classic grass-court tennis. Borges, however, controlled his own service games better at the key moments, did not allow the duel to spill into a series of tie-breaks and made use of the opportunities when Struff was left without enough first serves or precision in the rallies. In both sets, the final games decided the outcome, and the Portuguese tennis player came out of them with more concentration and fewer errors.
The key moments came at the end of the sets
The first set ended 6:4 for Borges, and its value was greater than the number on the scoreboard itself. On grass, the advantage of one break is often enough if a player maintains a high level of serving, and Borges managed to do exactly that. Struff tried to remain aggressive, but he did not find enough consistency to reverse the rhythm of the set. The Portuguese tennis player kept his line of play firm, chose his moments to move toward the net and did not enter into unnecessarily risky shots when he had a lead on the scoreboard. That approach enabled him to close out the first set without an additional extension and to shift the psychological burden onto his opponent.
The second set was similar in structure, but even more sensitive in terms of scoreboard pressure. Struff stayed in the match and at 5:5 had the chance to take the finish toward a tie-break, which on this surface would have been especially dangerous for Borges. Still, it was precisely then that the Portuguese player found the best combination of patience and attack. According to the official ATP result, Borges reached 7:5 in the second set and thereby avoided a third set, and that is important in the tournament context because Mallorca is played in a packed schedule immediately before Wimbledon. Instead of a long match with an additional physical cost, Borges finished the job in two sets and preserved enough energy for the quarterfinal challenge.
Struff’s defeat does not change the fact that in Mallorca he made a step forward compared with earlier appearances. According to a report by the German newspaper WELT, the 36-year-old German was back in the main draw of the tournament in Santa Ponça for the first time since 2022 and this year passed the first round there for the first time. In his opening appearance, he defeated Martin Landaluce 6:3, 1:6, 7:5, which is also confirmed by the official ATP Tour results. Against Borges, however, he did not manage to repeat the same level in the closing stage of the third part of the contest, because he did not even force a third set. WELT also reported that the match and the day were played in conditions of great heat, with temperatures above 30 degrees, which further increased the importance of quick decision-making and economical movement.
Borges confirms a good week after victory over Mannarino
Borges entered the round of 16 after a convincing victory over Adrian Mannarino, the tournament’s eighth seed, whom he defeated in the first round 6:2, 6:2. After that match, the ATP Tour highlighted that Borges had become the first Portuguese tennis player with a victory at the Vanda Pharmaceuticals Mallorca Championships. The same source stated that it was his second victory over a player from the Top 50 group on grass, after he had previously defeated Francisco Cerundolo in the first round of Wimbledon in 2025. That background gives additional weight to the victory over Struff, because it shows that Borges is not building his result on grass on just one surprise, but on an increasingly clear pattern of adapting his game.
The Portuguese tennis player is not known as a grass specialist in the traditional sense, but in Mallorca he showed the elements he needs on that surface. His serve is not exclusively a weapon for winning easy points, but a tool with which he opens the court for the first next shot. In rallies, he tries to avoid being late on the low bounce, and against Struff it was especially important that he not allow the German to take the initiative too often with the forehand from the middle of the court. In moments when Struff looked for a quick entry into the point, Borges responded with deep balls and a rational choice of direction, which helped him neutralize part of his opponent’s aggression. It was precisely that combination of tactical discipline and calmness on the scoreboard edge that marked his passage among the best eight.
For Borges, the Mallorca quarterfinal is significant also in terms of points. According to the ATP Tour’s tournament preview, a singles quarterfinalist earns 50 ATP points and prize money of 18,515 euros, while the tournament winner receives 250 points and 93,175 euros. The total prize fund for the singles and doubles program is listed at 612,620 euros. These data are not only the financial framework of the tournament, but also an explanation of why every run at ATP 250 level is important for players fighting for a better position in the rankings and a more favorable status in the draws of bigger competitions. In the closing stage of the grass season, several successful matches can significantly change the rhythm of entering a Grand Slam week.
The quarterfinal brings a duel with top seed Luciano Darderi
The official ATP draw after the round of 16 paired Borges with Luciano Darderi, the top seed in Mallorca. Darderi reached the quarterfinal with a 7:5, 6:3 victory over Yannick Hanfmann, also according to the official ATP Tour results. That duel brings Borges a different tactical task from the meeting with Struff. In 2026, Darderi comes to Mallorca as one of the bearers of the tournament’s weight, and his position at the top of the draw means that he will demand from Borges an even higher level of stability in service games and a greater ability to impose himself in longer exchanges.
In the quarterfinal phase of the tournament, the room for a slow entry into the match is considerably smaller. Against Darderi, Borges will have to preserve what was most valuable against Struff: a cooler head in the closing stages of sets. If he repeats the model from the round of 16, in which he waited for the right moment and did not rush under pressure, he could create a new opportunity for a big result. But Darderi, as the top seed, will probably try to take control of the tempo earlier, especially if he gets enough short balls after the return. Therefore Borges’s first serve and the depth of his second shot will be one of the key technical points of the quarterfinal.
Interesting outcomes have already opened up in the same part of the draw. According to the official ATP results, Miomir Kecmanović defeated Lorenzo Sonego after a comeback 2:6, 7:6(4), 6:4, while Fabian Marozsan beat fourth seed Alejandro Tabilo 6:2, 6:3. These results confirm that the tournament in Mallorca did not bring a calm passage for the seeds and that grass once again rewarded players who accepted the conditions more quickly. Borges’s success against Struff is therefore not an isolated result, but part of the broader picture of a competition in which favorites have to justify their status from the first ball. For spectators and organizers, that creates a more open finish, and for players an opportunity to make an important step forward in the last week before Wimbledon.
Mallorca as the final grass-court test before Wimbledon
In its official preview, the ATP Tour states that the Vanda Pharmaceuticals Mallorca Championships 2026 is being held from 21 to 27 June at the Mallorca Country Club, with qualifying having started on 20 June. It is an ATP 250 category tournament played on grass and it occupies an important place in the short transition between the clay season and Wimbledon. The official Wimbledon website states that The Championships 2026 are played from 29 June to 12 July, so Mallorca represents the final competitive test for many players before arriving in London. Because of that, every match is viewed not only through the current result, but also through the question of form, health and the ability to adapt to the specific bounce of a grass surface.
In such a calendar, Borges’s victory has double value. On the one hand, it brings him points, a prize and a place in the quarterfinal of a tournament that gathers players of different profiles, from pronounced servers to players who try to shorten rallies on grass with precise attacking play. On the other hand, it gives him a competitive signal that he can survive difficult stretches against an experienced opponent and finish a match without a drop-off in the closing stages of sets. For Struff, the defeat means the end of his Mallorca appearance, but also several useful matches ahead of the continuation of the grass season. For Borges, however, the tournament continues against the top seed, and it is precisely that meeting that will show whether he can turn the victory over the German veteran into an even stronger result at one of the last grass-court tests before Wimbledon.
