SINGAPORE — Daria Kasatkina needed one set to show she belonged in the Singapore draw and another to show she did not.
Aliaksandra Sasnovich, ranked 136th and carrying the kind of profile that WTA 500 draws are designed to manage by Tuesday, dismissed Kasatkina 7-5, 6-0 on Day 1 of the Singapore Tennis Open presented by BNP Paribas, delivering the tournament’s first significant result before any top-seeded player had touched the court. According to the WTA, the match was a Round of 32 clash. It was the match Kasatkina was supposed to win. The second-set bagel made the distance between them look considerably wider than the 51 ranking places that actually separated them.
Sasnovich won the first set in a grind. Both players held serve through the early stages until Sasnovich landed a break to take it 7-5. Then came the second set, and something that resembled a different match entirely. She broke Kasatkina in the opening game, held to consolidate, broke again, held again. Kasatkina’s replies grew shorter and eventually stopped coming. By the time Sasnovich served out the 6-0, the scoreboard had constructed a picture bearing no resemblance to the competitive first set.
What drove the collapse is the question Kasatkina left without an answer after the match. She offered no public comment on her condition. A 0-6 second set at a 500-level event against a player ranked 51 places below carries weight beyond tactical explanation. Whether fatigue from the North American hard-court season, an undisclosed physical issue, or the psychological difficulty of dropping a tight first set at 7-5 played any role, Kasatkina did not say. That gap is the one thing Monday’s result could not clarify.
Sasnovich is 32 and has spent a career producing results her ranking has never quite rewarded. She won through qualifying rounds at Grand Slam events in her best years, reached the fourth round at Wimbledon in 2018, and peaked at No. 29 in September 2022 before sliding back through the 100s. At 136 entering Singapore, she operates in a circuit now headed by Elena Rybakina, who claimed the world No. 1 ranking after winning the US Open women’s final last weekend. She is the sort of player Asian swing draws tend to absorb quietly. On Monday, she refused that role.
Her win reshapes the upper half of the draw. Kasatkina had been positioned as the most credible challenge in the section assigned to top seed Mirra Andreeva, the world No. 5 and Roland-Garros champion who stepped into the top spot after Jessica Pegula withdrew before the draw was made. Andreeva received a first-round bye and begins her campaign on Tuesday. Kasatkina had beaten Andreeva before and her aggressive baseline tennis is the kind that stretches the top seed’s defensive range. That test no longer awaits. Andreeva’s path through the upper half clears considerably after Day 1.
The 2026 Roland Garros title was Andreeva’s first Grand Slam, a win that confirmed her arrival at the top of a women’s circuit in transition. Andreeva is now the only top-10 player in the Singapore field. When asked ahead of the tournament whether she felt pressure as the clear favorite, she said the draw was strong enough that the framing did not apply.
The Singapore Tennis Open has changed in stature this year. Its elevation to WTA 500 status makes it Southeast Asia’s only event at that tier. The prize pool of $1,206,446 sends $185,000 and 500 ranking points to the singles champion. As Yahoo Sports reported, the WTA’s fall Asian swing kicked off simultaneously with the Korea Open in Seoul, a WTA 250 event running the same week and splitting the field across two cities. Singapore carries the higher billing.
Amanda Anisimova is the second seed. Alexandra Eala, the third seed, is the first Filipino player seeded at a WTA 500 event and has drawn the loudest anticipation of any player in Singapore. Elise Mertens, the defending champion, is seeded fourth and begins Tuesday in the opposite half of the draw from Andreeva.
Sasnovich’s second round will carry more information about Monday than Monday itself can supply. Her route likely leads to Mertens at some stage, giving the Belgian defending champion a chance to establish that the 0-6 was a single-match anomaly. Singapore has the week to run, and the draw has not settled on anything yet.
