Jessica Pegula has withdrawn from the Singapore Open, removing the tournament’s top seed after what she described as “a long and physically demanding few weeks”. The world No 3 had been set to lead the WTA 500 entry list, but said she is “not quite ready” to return after a packed North American hard-court stretch that left her with 19 matches in just over a month.

Pegula’s results over that period show how busy the run has been. She opened with a runners-up finish at the Washington DC Open, then reached the round of 16 at the Canadian Open. She later went back to the United States, where she lost the Cincinnati Open final before falling in the semi-final of the US Open.

“I’m really disappointed to have to withdraw from Singapore,” she wrote on social media. “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.

“I was really looking forward to playing in Singapore and hope I can come back in the future.”

Organisers have not yet announced her replacement, but Pegula is the third seeded player to withdraw and the seventh player overall to pull out of the event.

World No 13 Diana Shnaider, who had been in line to seed fourth, also withdrew, as did fifth seed Sorana Cirstea, ranked No 15. Ekaterina Alexandrova, Anastasia Potapova, Ann Li and Clara Tauson are the other withdrawals.

The reshuffle has already moved several players into new positions. Alycia Parks, Daria Kasatkina, Talia Gibson and Aliaksandra Sasnovich have entered the main draw after earlier withdrawals. World No 5 Mirra Andreeva will now replace Pegula as top seed, while Amanda Anisimova will lead the bottom half.

World No 18 Alex Eala rises to third seed, with Elise Mertens, Maja Chwalinska, Sara Bejlek, Maria Sakkari and Barbora Krejcikova completing the seeded list.

Mertens is the defending champion after beating Li in the final of the inaugural edition in February 2025. The tournament has since been upgraded from a WTA 250 to a WTA 500 and moved to September.

Spain head into their Davis Cup qualifier against Chile without Carlos Alcaraz, with the trip to South America shaping up as a demanding assignment.

Alcaraz returned to competition at the US Open after a four-month absence caused by a wrist injury and reached the quarter-finals, but that short comeback window still left him in no position to be considered for team duty. Spain captain David Ferrer said the decision to leave out the world No 3 had effectively been made well before the squad was announced.

“Carlos, until the very last minute, there were doubts about whether or not he would play the US Open, so he was in a difficult position to compete,” Ferrer said.

“Obviously, the Davis Cup was very difficult for him to be with us, so from the very start I knew that scenario was practically impossible.

“Since then, Carlos has been making good progress; he had a great US Open and hopefully we’ll have the chance to reach the finals because he’ll certainly be with us then.”

Spain also do not have world No 30 Alejandro Davidovich Fokina available, which leaves them with a mixed group for the tie in Santiago. The squad is headed by 19-year-old Rafael Jodar, the highest-ranked player at No 14 in the ATP Rankings, and he will make his Davis Cup debut alongside 21-year-old Daniel Meida, ranked No 41, and 20-year-old Martin Landaluce, who sits at No 62.

The more experienced pair, Jaume Munar and Pedro Martinez, both 29, are set to handle doubles duties.

Chile, meanwhile, will look to use home conditions to their advantage. Captain Nicolas Massu said: “My priority was to put Chile among the best in the world. Having an opportunity to play against Spain at home is something we have to take advantage of,” the former world No 9 said.

“We’re going to approach this series with conviction. You live to face the best in the world. This generation can give much more to Chilean tennis.”

Chile advanced by beating a Novak Djokovic-less Serbia 4-0 in the first round of qualifiers, while Spain entered this stage as the runners-up from the 2025 tournament.
