Berlin Ladies Open Day One Round-up | Diana Shnaider out to teenager Bartunkova as Alexandrova advances after Potapova retirement

The Berlin Ladies Open opening day featured three completed main-draw matches, including a straight-set retirement win for Ekaterina Alexandrova and a comeback victory for Elise Mertens against Liudmila Samsonova. Nikola Bartůňková also progressed after a three-set win over Diana Shnaider, with two of the three matches extending into decisive momentum swings during the second and third sets.

Conditions at the Berlin Ladies Open were disrupted by early rain delays during qualifying, but main-draw action produced contrasting match patterns between recovery-based wins and sustained three-set physical battles. The results shape the early Round of 16 picture, with higher-ranked players facing immediate pressure from opponents who adjusted more effectively after losing opening sets.

Alexandrova took immediate control of the match, building a 4-1 lead through consecutive breaks of serve as Potapova struggled physically after requiring a medical timeout. The Russian’s return pressure consistently pushed Potapova behind the baseline, preventing any stable service rhythm in the early stages of the opening set, which ended 6-1.

Potapova was unable to sustain the match beyond the opening set and retired shortly after Alexandrova had established a clear double-break advantage. The contest effectively tilted before any sustained second-set dynamics could develop, with Alexandrova already in full control of baseline exchanges.

Alexandrova was particularly efficient behind serve during the time the match lasted, conceding only four points on serve and winning 81% of her service points, compared to just 48% for her opponent. The Russian will face a significantly tougher test in the second round at the Berlin Ladies Open, where she is set to meet world No. 1 Aryna Sabalenka.

Bartůňková, 20, competing with a wildcard, produced one of the standout wins of the opening day at the Berlin Ladies Open, overcoming Diana Shnaider in three sets to secure a significant ranking jump up to No. 51. The Czech controlled the opening set 6-2 through early breaks and consistent service holds, establishing early structural dominance in the match.

Shnaider responded in the second set by increasing return pressure and forcing a tie-break, where Bartůňková was unable to convert key match points before the set slipped away. Despite losing that momentum swing, she recovered emotionally in the deciding set and re-established control from the baseline to close out the match 6-3.

Statistically, Bartůňková converted 7 breaks from 15 opportunities, compared to Shnaider’s 4 breaks from 8 chances, reflecting a high-volume break exchange throughout the contest. She also won 61% of service points against 53% for Shnaider, a marginal but decisive edge across extended service games. This marks the biggest win of her career to date, her first victory over a top-20 player, and she progresses to the second round at the Berlin Ladies Open with strong momentum.

Samsonova opened with clear dominance, breaking early to establish a 3-0 lead and winning the first set 6-1 through consistent first-serve efficiency and limited error exposure. Mertens struggled to find depth in return games, with Samsonova controlling baseline exchanges in the opening phase.

The match shifted in the second set as Mertens improved return positioning and began extending rallies, breaking serve and moving ahead 4-1 after sustained pressure on Samsonova’s second serve. That adjustment reduced Samsonova’s ability to dictate early points and forced longer exchanges, where Mertens gained control.

In the deciding set, Mertens completed a full momentum reversal, winning 6-0 without conceding a game. The Belgian maintained high first-serve points won and converted multiple break opportunities, while Samsonova’s level dropped significantly after losing early service games.

Mertens progresses to the second round at the Berlin Ladies Open after a full match turnaround, eliminating a former champion. She will face the 20-year-old Nikola Bartůňková for a place in quarterfinals.
