The British player reached the third round in three out of four Grand Slams this year.
Emma Raducanu from Great Britain will not compete in her remaining competitions of the year as a result of a medical condition she has been fighting in recent days.
At 22 years old was due to play in Tokyo and Hong Kong but chose to travel back to recover ahead of launching plans for the 2026 season.
Her upcoming training are set to feature her coach Francisco Roig, as they have agreed to work together for the upcoming season.
She had her blood pressure taken during her first-round match versus Ann Li in Wuhan and withdrew when behind 6-1 4-1 on a very muggy occasion.
Another medical visit was necessary a doctor's assessment at the recent Ningbo Open, where she lost in three sets to Chinese wildcard Zhu Lin in round one.
She was also playing with clear difficulty in the third set in the match with Zhu due to a lower back issue that has been a concern at times this year.
Those results meant an encouraging season, in which she climbed into the world's top 30 after a long gap for the first time since 2022, concluded with three straight losses.
She held three match points before losing to Jessica Pegula in the third stage in the Beijing tournament last month.
Raducanu won 28 matches during 2025 and advanced to the semis in Washington, but her most impressive week was at the Miami event in March.
The British number one made the last eight of this WTA 1000 tournament, defeating eighth seed Emma Navarro en route then falling in three sets to the world number four Pegula.
She was coached by trainer Mark Petchey from Miami until Wimbledon, with Roig taking over ahead of the US Open.
The first plan with the ex-coach of Rafael Nadal was through the season's conclusion but the collaboration persists, with a training block pencilled in for the end of the year.
Raducanu told that her three-day trial with Roig after Wimbledon was like a "secret mission" as they tried to keep the meeting secret.
The player was close to overcoming Sabalenka, the world number one at their initial event as a team in Cincinnati in August.
Roig joined her in New York, where she made the third stage before being beaten by Rybakina, champion at Wimbledon in 2022.
