Zverev breaks Collignon after two tie-breaks and reaches the ATP semifinal in Halle
Alexander Zverev advanced to the semifinals of the Terra Wortmann Open in Halle after defeating Belgian qualifier Raphael Collignon 7:6(10), 7:6(2). The quarterfinal duel, played on 19 June 2026 in Halle, Germany, went to two tie-breaks, which says enough about the level of pressure under which both players performed. According to the official report by the tournament organizers, Zverev reached the last four after two hours of play, although the difference between the players was minimal during most of the match. The ATP Tour confirmed in its official results that the top seed defeated the qualifier from Belgium 76(10), 76(2), continuing his run on the grass court of the ATP 500 tournament. For Zverev, this is another important step in his attempt to win the Halle title that has so far eluded him, despite multiple deep runs into the final stages of the tournament.
A match in which details decided every set
From the very beginning, the first set suggested a duel in which serve, concentration and reactions on the most important points would play a decisive role. The tournament organizers state that Zverev already had two break points in Collignon's first service game, but failed to convert them, after which both players held serve for a long time without major cracks. In such a rhythm, every return point gained additional weight, especially because on the grass in Halle points are often shortened by a good first serve and an aggressive first shot after it. Collignon, who entered the main draw through qualifying, did not behave like a player satisfied merely with reaching the quarterfinals, but already in the opening set showed that he could remain equal in fast exchanges and under the pressure of the crowd in the OWL Arena. Zverev, on the other hand, had to accept that he would not get many easy opportunities and that the victory would have to be built patiently, without a quick separation on the scoreboard.
The most dramatic part of the first set came in the tie-break, in which Zverev first led 4:1 and looked as if he was taking control. According to the official match description on the Terra Wortmann Open website, Collignon came back with a mini-break and then, with powerful serves, earned three set points. Zverev saved all of them, and then converted his third set point for 12:10 in the tie-break, finishing the key point with a backhand down-the-line passing shot. That outcome carried great psychological weight because the Belgian was very close to taking the lead in the first set, while Zverev showed the experience of a player used to making decisions at the highest level. In grass-court matches, such moments often reverse the dynamics, because a lost tie-break after missed set points can be a harder blow than an ordinary loss of serve.
Zverev survives danger in the second set and closes out the match
The second set did not bring a sudden drop in Collignon's level. On the contrary, the Belgian tennis player continued to hold serve and wait for an opportunity on Zverev's opening shot. The tournament organizers point out that the next break point came only in the middle of the second set, this time for Collignon, but Zverev neutralized it with a powerful serve down the line and soon leveled at 4:4. That moment was just as important as saving the set points in the first tie-break, because Collignon could then have taken the initiative and opened the way toward a third set. Instead, Zverev maintained his serving rhythm, and the set once again turned into a game of nerves in the closing stages.
In the second tie-break there was no longer the same uncertainty. Zverev quickly led 3:0 and, unlike in the first set, did not let the advantage slip away again. According to the official tournament report, the German tennis player converted his second match point and closed the tie-break at 7:2, thereby avoiding a third set and additional exertion in conditions that demanded physical and mental resilience from the players. The German agency dpa, carried by Welt, reported that both players hit 14 aces each, a figure that well describes how much the match was focused on serve and how difficult it was to make the decisive breakthrough in return games. The same source states that play took place in high temperatures, up to around 30 degrees Celsius, so during changeovers the players sought cooling under umbrellas and with ice bags. In such circumstances, Zverev's ability to remain calm in two tie-breaks was the decisive value of the victory.
Collignon's week remains one of the surprises of the tournament
Although he was stopped in the quarterfinals by defeat, Raphael Collignon achieved one of the most notable results of his career at ATP level in Halle. According to the official text by the organizers after his victory over Mattia Bellucci, the Belgian tennis player reached the quarterfinals with his fourth consecutive victory of the week and became only the eighth qualifier in the tournament's history to reach the last eight. In the round of 16, he defeated Bellucci 4:6, 6:4, 6:3, and the organizers presented him as a player who at that moment was 51st in the ATP rankings. That piece of information further explains why Zverev's passage should not be viewed only through the difference in seeding status, but also through the fact that on the other side of the net stood an in-form opponent, with several matches already played and won on the same surface.
Collignon confirmed in the match against Zverev why he had come so far. He did not fall apart after the missed opportunities in the first set, and in the second he himself had a break point that could have changed the course of the match. His performance showed that qualifiers on grass, especially when they have already felt the rhythm of the tournament, can be very dangerous even for highly seeded players. On a grass surface, differences are often reduced because a good serve and early aggression can neutralize part of the advantage that favorites usually have in longer exchanges. Collignon leaves Halle without a semifinal, but with a result that will bring him additional visibility in the tennis calendar and confirmation that he can compete with players from the very top.
Halle as an important stage of the grass-court season
The Terra Wortmann Open is one of the most important tournaments in the short grass-court season leading toward Wimbledon. According to the ATP Tour, the 2026 edition is being held in Halle from 15 to 21 June, with qualifying having begun on 13 June, and the tournament belongs to the ATP 500 category. Official ATP preview materials state that it is played in the OWL Arena, that the tournament was founded in 1993 and that the tournament director is Ralf Weber. The same source states that the prize fund amounts to 2,583,330 euros, and the winner in singles receives 500 ATP points. Such status of the tournament explains why the 2026 draw also gathered a number of highly ranked players, including Zverev, Felix Auger-Aliassime, Ben Shelton, Taylor Fritz, Daniil Medvedev and defending champion Alexander Bublik.
For Zverev, Halle carries special sporting weight. According to the tournament organizers, the German tennis player is now in the semifinals of the Terra Wortmann Open for the sixth time, and the preview of semifinal day also stated that this is his fourth consecutive semifinal appearance in Halle. The same source recalls that in his tenth appearance at the tournament he is trying to reach his first final there since 2017. The ATP historical tournament database shows that the last German winner in Halle was Florian Mayer in 2016, while Roger Federer is the tournament record holder with ten singles titles. Zverev is therefore still searching for a title that would have both competitive and symbolic significance, especially because this is one of the most visible grass-court tournaments outside Grand Slam level.
A semifinal with Fritz brings a different profile of threat
Zverev will play in the semifinal against Taylor Fritz, the fifth seed, who defeated Ben Shelton in the quarterfinals 6:7(5), 7:6(8), 7:6(3). The ATP Tour confirmed that result in its official review of quarterfinal day, and the tournament organizers described Fritz's victory as another encounter in which serve and tie-breaks decided almost everything. Fritz, according to the official tournament text, reached victory without a single break point in the entire match, which further emphasizes how much the grass surface in Halle rewarded players who could maintain a high percentage and quality of first serves. The same report stated that the American saved a match point in the second tie-break and reached the semifinal after two hours and 45 minutes.
The semifinal pairing Zverev – Fritz has additional weight because of their head-to-head record. The tournament organizers state that Zverev has a 5:9 record against Fritz, and especially important is the fact that the American tennis player has won their last six meetings. In the preview of semifinal day, Zverev said that he wants to reach the final and expects a difficult match, while Fritz emphasized that he has already played against Zverev in Germany several times and that support from the stands did not decisively change their duels. These statements point to a semifinal in which Zverev will not be able to rely only on a good serve and psychological stability, but will have to find a way to break the pattern of recent head-to-head defeats. Fritz, on the other hand, arrives with a victory that gave him additional confidence because he survived one of the most demanding matches of the tournament.
The road toward the final stages remains open, but demanding
Zverev's passage against Collignon is important also because of the broader context of his grass-court part of the season. The tournament organizers in Halle describe him as the new Roland Garros champion, which gives his appearances on grass additional attention because a player of such status is expected to adapt quickly from the Paris clay to a much faster surface. In his first three appearances in Halle he had to solve different types of challenges: against Vít Kopřiva he played three sets, against Yannick Hanfmann he, according to the ATP, reached the quarterfinals with a 6:3, 7:6(4) victory, and against Collignon he had to save set points and close the match without a break. Such a sequence shows that his form is not only a matter of dominant results, but also of the ability to escape situations in which a favorite's advantage can melt away very quickly.
The quarterfinal in Halle was therefore not a routine victory for the top seed, but a test of stability in conditions in which the margins were extremely narrow. Zverev won both tie-breaks, saved his opponent's key chances and avoided a third set that could have further burdened the schedule ahead of the semifinal. Collignon, despite the defeat, played a match that confirms that his quarterfinal result was not accidental. The final stages of the Terra Wortmann Open now continue with two semifinals in which, according to the official ATP results, Zverev, Fritz, Frances Tiafoe and Daniel Altmaier remain. In such an outcome, Zverev's next task will be significantly different from the challenge against Collignon: against a player who has regularly caused him problems recently, he will have to maintain the same calmness on key points, but also find more room on return than he had in the quarterfinal.
