The British player made it to the third stage in three out of four Grand Slams during the season.
Britain's Emma Raducanu has pulled out of her final two events this season because of a medical condition she has been fighting over the past 10 days.
Raducanu, aged 22 was due to play in tournaments in Tokyo and Hong Kong but has decided to fly home to regain her health ahead of launching next year's training.
Her upcoming training are set to feature coach Francisco Roig, as both individuals have decided to continue collaborating again next season.
Raducanu had her blood pressure taken during her first-round match against Ann Li in Wuhan and withdrew when behind 6-1 4-1 on a day with extreme humidity.
She again required a visit from the doctor at the Ningbo Open this week, where she was defeated in three sets to Zhu Lin, a Chinese wildcard in the first round.
Raducanu was also moving with clear difficulty in the deciding set against Zhu owing to a lower back issue that has been a concern at times this year.
Such performances signaled a promising season, in which the player advanced into the world's top 30 for the first time for the first time since 2022, ended with three successive defeats.
Raducanu had three match points then was defeated by American player Jessica Pegula in round three in Beijing last month.
She secured twenty-eight matches during 2025 and advanced to the semis in Washington, but her most impressive week was at the Miami Open in March.
As Britain's top player made the last eight of the WTA 1000 event, beating eighth seed Emma Navarro during the tournament before losing in three sets to the world number four Pegula.
Her coach was Mark Petchey as coach from the Miami event through Wimbledon, with Roig assuming the role in time for the US Open.
The initial agreement with the former trainer of Nadal was until the end of the season but the collaboration persists, with a training block pencilled in for the end of the year.
Raducanu told that a three-day test period alongside Roig after Wimbledon was like a "secret mission" as they aimed to maintain secrecy.
The player was close to overcoming Sabalenka, the world number one at the first competition with Roig in Cincinnati in August.
Roig was also with Raducanu in the New York tournament, where she made the third stage before being beaten by 2022 Wimbledon champion Elena Rybakina.
