The Singapore Open has been disrupted by an unusually heavy run of withdrawals as the Asian swing gets underway on the WTA Tour. The event, first on that part of the calendar after the US Open, has already been affected by the physical demands that typically follow a long North American hard-court stretch. Travel, time-zone changes and overall fatigue have all shaped the picture in Singapore.

The list of absentees has grown steadily, with Amanda Anisimova, Jessica Pegula and Diana Shnaider among the seeds who have already pulled out. Even with the tournament in progress, the attrition has continued.

Barbora Krejcikova is the latest player to exit, and her withdrawal came after she had won her opening-round match. The two-time Grand Slam champion has pulled out of her round of 16 meeting with defending champion Elise Mertens because of a lower back injury.

That development moved Mertens straight into the quarter-finals without needing to step on court. She will now face Roland Garros breakout star Maja Chwalinska for a place in the semifinals.

The draw has also placed Alex Eala and Mirra Andreeva in the position of top two seeds, and both now look well placed to progress deep into the event. Andreeva opens against Aliaksandra Sasnovich, while Eala faces Tatiana Prozorova for a place in the last eight.

With so many withdrawals already recorded, the tournament offers a clear opening for both players. Andreeva could win the title without facing a single opponent ranked inside the WTA top 10, especially after Pegula’s withdrawal earlier in the week. The highest-ranked player she may meet before the final is Mertens, who is world No 19. For Eala, the highest-ranked possible opponent before the final is world No 33 Maria Sakkari.

The Singapore Open is due to open the WTA Tour’s Asian swing, but the field has thinned considerably before the first ball is struck.

The WTA 500 event starts on September 21st, with Mirra Andreeva, Alex Eala and Amanda Anisimova among those still scheduled to compete. The draw has already been completed, and it had pointed toward a possible final between Andreeva and Eala. Even so, the list of withdrawals has kept growing.

Janice Tjen became the latest player to step out of the tournament, pulling out just one day before it was set to begin. She said a right wrist injury was behind the decision.

Tjen is the 10th player to withdraw from the event and joins a group that includes Jessica Pegula, Diana Shnaider and Sorana Cirstea. Pegula, who would have been the top seed, announced her withdrawal on social media.

“I’m really disappointed to have to withdraw from Singapore,” Pegula said via an Instagram Story on the 15th September, less than a week before the tournament was set to begin.

“After a long and physically demanding few weeks at the US Open, I’m just not quite ready to get back on court and compete at the level I expect from myself,” said the US Open 2026 semi finalist. “I was really looking forward to playing in Singapore and hope I can come back in the future.”

The withdrawal list also includes Diana Shnaider, Sorana Cîrstea, Anastasia Potapova, Ekaterina Alexandrova, Sára Bejlek, Ann Li, Clara Tauson and Mayar Sherif. Each has been replaced in the draw, with some spots going to named alternates and others to a qualifier or lucky loser.

The Singapore Open will serve as a lead-in to the China Open, the penultimate Masters tournament on the WTA Tour calendar. The event runs from September 21st to September 27th, ending three days before the China Open begins.

Elise Mertens will return as the defending champion after winning the title in 2025, and she enters the WTA 500 event as the fourth seed.

Alex Eala will need to negotiate a difficult field if she is to lift the Singapore Open title next week.

As the third seed, the 21-year-old has received a bye into the second round after being placed among the top four seeds. Her opening opponent will be either world No 152 Sofia Costoulas or world No 178 Tatiana Prozorova, a first-round match that will decide who meets the Filipina first.

Eala has not played either player before. If she comes through that match, the route could quickly become more demanding, with Queen’s Club champion and former world No 17 Donna Vekic waiting in the quarter-finals.

Eala leads Vekic 2-0 in their head-to-head after winning both meetings this year. The first came in Auckland, where she prevailed in three sets, while the second was a straight-sets result in Berlin. Those contests were tight, underlining the scale of the challenge ahead.

Should Eala move beyond that stage, second seed Amanda Anisimova could stand in her way in the semi-finals. The American won their only meeting in Cincinnati in August, taking a three-set battle as Eala fell 4-6, 6-4, 6-2 in her final warm-up event before the US Open.

The upper half of the draw also places Mirra Andreeva in contention for the final, with the French Open champion projected to meet defending champion and fourth seed Elise Mertens in the semi-finals. Eala has never faced Andreeva on the WTA Tour, though she did defeat the Russian on the way to the girls’ singles title at the 2022 US Open.

There are other players capable of complicating the draw, including Maja Chwalinska, Leylah Fernandez, Barbora Krejcikova and Maria Sakkari. In other parts of the bracket, Andreeva may open against Daria Kasatkina or Aliaksandra Sasnovich, while Anisimova is set to begin against Talia Gibson or wild card Fiona Ferro.

The event has been upgraded from a 32-player WTA 250 held in late January last year to a 28-player WTA 500 in 2026. Eala, Andreeva, Anisimova and Mertens have already secured 60 ranking points and $18,045 in prize money by receiving byes into round two.

The champion will earn $185,500 and 500 points, while the runner-up will take home $114,500 and 325 points. The main draw starts on Monday.
