Sabalenka came back from a large deficit and, with a turnaround, secured the semifinal of the WTA tournament in Berlin
Aryna Sabalenka, the top seed and leading player in the WTA rankings, secured a place in the semifinals of the VANDA Pharmaceuticals Berlin Tennis Open after one of the most demanding matches of her grass-court season. In the quarterfinal played on June 19, 2026, in Berlin, she defeated Czech player Nikola Bartunkova 2:6, 7:6(2), 6:4, after losing the first set and trailing 0:4 in the second. According to the WTA report, the match lasted two hours and 23 minutes, and by reaching the last four players in Berlin, Sabalenka continued her pursuit of the title at one of the most important preparatory tournaments ahead of Wimbledon. The result was also confirmed by the official WTA draw, in which Sabalenka is listed as the quarterfinal winner and semifinalist. For Bartunkova, the defeat was painful given her large lead in the second set, but her performance confirmed that the 20-year-old Czech is increasingly establishing herself at the highest level of women’s tennis.
The turnaround after 0:4 in the second set changed the course of the match
Sabalenka entered the encounter as the clear favorite, but the beginning of the match did not reflect that status. Bartunkova won the first set 6:2, aggressively attacked her opponent’s second serve and successfully varied the rhythm of the rallies. According to the WTA’s description of the match, the Czech player used sliced shots, drop shots and frequent changes of direction to throw Sabalenka off balance. That plan also brought her a 4:0 lead in the second set, a moment when the match looked very close to a major upset. After that, Sabalenka found a way to shorten the points, move more often toward the net and avoid exchanges in which Bartunkova had until then managed to impose her variety.
According to the same WTA report, the key turning point occurred in the games in the middle of the second set, when Sabalenka began to return the pressure and saved a chance that could have allowed Bartunkova to move ahead 5:2. That moment not only stopped the Czech player’s run but also opened space for a change in the emotional dynamics on the court. Sabalenka won eight of the next ten games, including the closing stages of the second set and the beginning of the third. She played the second-set tie-break in her most stable manner of the entire match, and the WTA states that the last six points of the tie-break went her way. With that, the match suddenly shifted from what looked like an almost settled upset into a duel in which the top seed took control again.
The third set was not a simple formality for Sabalenka. Although she immediately broke Bartunkova at the start and took a 2:0 lead, the Czech player came back twice from a break down and reached a 4:3 lead. In doing so, she once again showed that her resistance was not merely the result of a weak start by the top seed, but also of her own ability to adapt on grass to short, unpredictable points. The closing stages nevertheless belonged to Sabalenka, who at 4:4 found several powerful forehands and then used her serve to finish the match. In its report, the WTA particularly highlighted her final forehand as the shot with which she confirmed her passage into the semifinals.
Bartunkova confirmed her rise despite the defeat
Nikola Bartunkova competed in Berlin with an organizer’s invitation, and according to the official WTA player list for the tournament she was marked as a wild card participant. Although against Sabalenka she fell short of a victory that would have been the biggest of her career, the way she constructed points showed why her performance in Berlin attracted attention. Before the quarterfinal, the WTA reported that Bartunkova had defeated Elise Mertens 6:1, 6:4 in the previous round and thereby secured her first grass-court quarterfinal at this level. In that match, according to the WTA, she saved five of six break points and used variations, volleys, sliced shots and changes of angle well. That style of play was also visible against Sabalenka, especially in the first set and a half.
Tennis.com stated in its quarterfinal data that Bartunkova was the world No. 62 at the time of the match, while Sabalenka was No. 1 in the WTA rankings. That difference in ranking was not visible on court for long, because the Czech player started the duel better and in the opening phase more often found solutions in return games. According to Tennis.com statistics, Bartunkova won 73 percent of points after landing her first serve, which shows how effective her first shot was when she found the court. At the same time she had eight aces, only two fewer than Sabalenka, confirming that her serve on grass can be a serious weapon. The problem appeared on the second serve, where she won only 35 percent of points, and precisely that segment became increasingly important as the pressure grew in the closing stages.
After the match, according to the WTA, Sabalenka praised Bartunkova and described her as a player of exceptional potential. Her words were important because they did not come after a routine victory, but after a match in which her opponent had long been closer to advancing. Bartunkova ended her singles campaign with the defeat, but her Berlin week remained marked by victories over Diana Shnaider and Elise Mertens, as well as an even challenge against the world No. 1. For the young Czech player, this is a result that may have broader significance in the continuation of the season, especially on grass courts where her creativity fits well with the faster playing conditions.
The statistics reveal how unstable the match was
The match statistics confirm that the encounter was full of swings. Tennis.com reported that Sabalenka finished the duel with ten aces and eight double faults, while Bartunkova had eight aces and seven double faults. Such numbers explain why both players had periods of dominance, but also stretches in which they offered their opponent a way back. Sabalenka landed 66 percent of her first serves and won 63 percent of points after her first serve, while on second serve she was considerably more stable than Bartunkova, with 64 percent of points won. It was precisely that difference on second serve that helped her in moments when she had to halt the Czech player’s surges.
Return games were equally important. According to Tennis.com, Sabalenka converted five of eight break points, while Bartunkova converted six of 17 opportunities. That figure describes the paradox of the match well: Bartunkova created more chances to break serve, but did not turn enough of them into a lasting scoreboard advantage. Sabalenka, on the other hand, was more effective when she reached break point, although for much of the match she looked uncertain in rallies and on serve. In the closing stages of the third set, effectiveness in the key points proved decisive, because Sabalenka responded better when every missed point could have turned into the end of the tournament.
The official WTA report emphasizes that in Berlin Sabalenka achieved her third victory of the 2026 season after losing the first set. Before this quarterfinal, she had similar comebacks against Elena Rybakina in the Indian Wells final and against Naomi Osaka in the Madrid round of 16, but the WTA stresses that none of those deficits was as deep as the one against Bartunkova. That fact gives additional weight to the victory, because Sabalenka had to deal simultaneously with scoreboard pressure, the tactical discomfort posed by her opponent and her own instability. In such circumstances, reaching the semifinals was not just the expected result from the top seed, but a demonstration of resilience after an almost lost position.
Pegula awaits in the semifinal on June 20, 2026
Sabalenka will play in the semifinal against Jessica Pegula, the third seed, who earlier the same day defeated Madison Keys 7:6(5), 7:6(8). According to the WTA report, that American quarterfinal duel lasted one hour and 46 minutes, and with the victory Pegula reached her fifth semifinal of the 2026 season. The WTA also states that Pegula took a 3:2 lead in her head-to-head record with Keys with that result. In the semifinal on June 20, 2026, two players will meet who reached the closing stages by very different paths: Sabalenka through a dramatic comeback, Pegula through two tie-breaks in a match in which she had to remain calm in the most important points. Such a contrast sets up a semifinal in which the rhythm of the rallies and service efficiency will be just as important as physical freshness after a difficult quarterfinal day.
The head-to-head record also gives broader context to the Sabalenka and Pegula duel. According to the WTA, Sabalenka leads 9:3 in their meetings at WTA Tour level, and she won their last meeting before Berlin in three sets at the WTA Finals in November 2025. Still, Pegula comes to Berlin as a player who knows how to control tempo on grass and use changes in height, length and direction of shots. In its report on her victory over Keys, the WTA pointed out that Keys won more total points, but Pegula was more precise in the key moments. That is the type of efficiency that can be decisive against Sabalenka, especially if the world No. 1 again has service fluctuations.
For Sabalenka, reaching a second consecutive Berlin semifinal is important also because of the psychological rhythm ahead of the continuation of the grass-court season. The WTA recalled that she also played the semifinal at this tournament in 2025, and her return among the four best players shows that she is gradually adapting to the surface after the transition from clay. The comeback against Bartunkova will not necessarily be an ideal tactical pattern for the rest of the tournament, but it can give her confidence from a situation in which she had to rescue an almost lost match. In grass-court tennis, such moments often have a strong effect, because a small change in the first shot or the return of serve can quickly turn an entire set around.
Berlin as an important test ahead of Wimbledon
The Berlin Tennis Open has a special place in the calendar because it is played immediately before Wimbledon and gathers a strong women’s draw on outdoor grass courts. In its official tournament description, the WTA states that the competition is held at the Steffi Graf Stadion in Berlin, belongs to the WTA 500 level and in 2026 is played from June 15 to 21. According to the same source, the tournament was once known as the German Open and has been part of the top-level WTA calendar since 1988. Since 2021 it has been played on grass, after a long history on clay, so in recent seasons it has become an important stop for players seeking form ahead of the biggest grass-court tournament of the season. The WTA also states that the center court holds up to 4,500 spectators, which gives the Berlin tournament the atmosphere of a major event, but also conditions specific enough for adapting to grass-court play.
In that context, Sabalenka’s victory has greater value than merely reaching the semifinals. Against Bartunkova she had to respond to a style of play that can be particularly awkward on grass: low balls, shortened exchanges, sudden approaches to the net and changes of rhythm. Such elements often break up the usual tempo of powerful baseline hitters, and in the first part of the match Sabalenka looked as though she did not have enough time to establish control. When she began more often to use the first shot after serve and look for shorter solutions, the match gradually turned. That is an important lesson for the continuation of the tournament, because against Pegula she will have to combine attack and patience without long periods of unforced errors.
For Bartunkova, Berlin remains proof that she can compete with the strongest players on fast surfaces. According to the WTA, her victory over Mertens was marked by creativity and good play under pressure, and against Sabalenka she strengthened that impression further. Although she missed out on reaching the semifinals, she played a match that will be remembered for a 6:2, 4:0 lead against the world No. 1 and for her ability to come back in the third set after an early break. Sabalenka ultimately advanced, but the manner in which she had to reach the victory also speaks to the depth of competition in women’s tennis. The Berlin quarterfinal duel was therefore not just another result in the draw, but a match that simultaneously confirmed the favorite’s experience and announced a new player capable of creating problems on the biggest stage.
