Emma Raducanu concludes the current season and plans to retain coach for 2026.
The British player made it to the third stage in three out of four Grand Slam events this year.
The British tennis star Emma Raducanu has withdrawn from her final two events this season due to a health issue she has been battling over the past 10 days.
Raducanu, aged 22 had planned to participate in Tokyo and Hong Kong but chose to travel back to recover ahead of launching next year's training.
Those preparations will involve trainer Francisco Roig, as they will keep partnering again next season.
She required blood pressure checks during her first-round match against Ann Li in Wuhan and retired when trailing 6-1 4-1 on a day with extreme humidity.
She again required a visit from the doctor at this week's Ningbo Open, where she was defeated in three sets to Zhu Lin, a Chinese wildcard in the first round.
Raducanu was also moving far from freely in the third set against Zhu due to the lower back problem that has been a concern at times this year.
Such performances signaled a promising season, in which she climbed into the world's top 30 after more than three years in more than three years, ended with three successive defeats.
Raducanu had three match points then was defeated by Pegula in the third stage in Beijing last month.
The player achieved 28 victories during 2025 and advanced to the semis in the Washington tournament, but her most impressive week was at March's Miami Open.
Ranked first in Britain advanced to the quarters of this WTA 1000 tournament, beating eighth seed Emma Navarro during the tournament then falling in three sets to the world number four Pegula.
She worked with trainer Mark Petchey between Miami and Wimbledon, with Roig assuming the role in time for the US Open.
The initial agreement with Rafael Nadal's former coach was through the season's conclusion but the collaboration persists, with planned training sessions for the end of the year.
She mentioned that her three-day trial with Roig post-Wimbledon was like a "covert operation" as they tried to keep the meeting secret.
The player was close to beating world number one Aryna Sabalenka at their initial event as a team in Cincinnati during August.
Roig joined her in New York, where she advanced to round three then falling to Rybakina, champion at Wimbledon in 2022.
