Emma Raducanu concludes her season and has decided to continue with trainer for 2026.
The British player advanced to round three in three out of four Grand Slams in the current campaign.
Britain's Emma Raducanu has withdrawn from her final two events in 2025 because of the illness that has affected her over the past 10 days.
At 22 years old had planned to participate in tournaments in Tokyo and Hong Kong but opted to return home to recover ahead of launching her preparations for 2026.
Those preparations will involve coach Francisco Roig, as the pair have agreed to work together for the upcoming season.
She had her blood pressure taken in her opening round versus Ann Li in the Wuhan tournament and retired when behind 6-1 4-1 on a very muggy occasion.
Another medical visit was necessary a doctor's assessment at this week's Ningbo Open, where she fell in a three-set match to Chinese wildcard Zhu Lin in the first round.
Her movement was noticeably restricted in the third set in the match with Zhu due to back discomfort that has been a concern at times this year.
These outcomes meant an encouraging season, in which the player advanced into the top 30 globally for the first time for the first time since 2022, concluded with three straight losses.
Raducanu had three match points then was defeated by Pegula in the third round in the Beijing tournament last month.
She secured 28 victories this year and advanced to the semis in Washington, but her standout performance was at the Miami Open in March.
Ranked first in Britain advanced to the quarters of the WTA 1000 event, defeating eighth seed Emma Navarro en route before losing in three sets to Pegula, ranked fourth.
She was coached by Mark Petchey from the Miami event through Wimbledon, with Francisco Roig stepping in for the US Open.
The initial agreement with Rafael Nadal's former coach was through the season's conclusion but they will keep working together, with a training session scheduled in the coming months.
The athlete revealed that her three-day trial with Roig after Wimbledon was like a "secret mission" as they tried to keep the meeting secret.
She came very close to beating world number one Aryna Sabalenka at their initial event as a team in August's Cincinnati tournament.
Roig joined her in New York, where she advanced to round three prior to losing to Elena Rybakina, the 2022 Wimbledon winner.
