Emma Raducanu ends this year's campaign and has decided to continue with her coach through next year.
The British player reached the third round in three Grand Slam tournaments Grand Slams during the season.
The British tennis star Emma Raducanu has pulled out of her final two events in 2025 because of the illness that has affected her over the past 10 days.
The 22-year-old had planned to participate in events in Asia but has decided to fly home to rest and recuperate ahead of launching plans for the 2026 season.
Her upcoming training will involve her coach Francisco Roig, as they will keep partnering in 2026.
Raducanu had her blood pressure taken in her opening round with Ann Li in the Wuhan tournament and retired when trailing 6-1 4-1 on a very muggy occasion.
She again required a visit from the doctor at the recent Ningbo Open, where she fell in a three-set match to local wildcard Zhu Lin in the opening round.
Her movement was noticeably restricted in the third set against Zhu due to a lower back issue that has been a concern at times this year.
These outcomes signaled a promising season, in which she climbed into the world's top 30 after more than three years in more than three years, concluded with three straight losses.
She held three match points before losing to Pegula in round three in last month's Beijing event.
The player achieved 28 matches in the current season and reached the semi-finals in Washington, but her standout performance was at March's Miami Open.
As Britain's top player advanced to the quarters of a premier WTA event, beating eighth seed Emma Navarro on the way prior to a loss in three sets to Pegula, ranked fourth.
She was coached by Mark Petchey from Miami until Wimbledon, with Francisco Roig stepping in ahead of the US Open.
The first plan with the ex-coach of Rafael Nadal was until the end of the season but they will keep working together, with a training session scheduled for the end of the year.
She mentioned that the trial session with Roig post-Wimbledon was like a "black ops mission" as they tried to keep the meeting secret.
She came very close to defeating top-ranked Aryna Sabalenka at their initial event as a team in August's Cincinnati tournament.
Roig was also with Raducanu in New York, where she advanced to round three before being beaten by 2022 Wimbledon champion Elena Rybakina.
