The British player reached the third round in three of the four major tournaments this year.
The British tennis star Emma Raducanu will not compete in the last two tournaments in 2025 because of a medical condition she has been fighting in recent days.
The 22-year-old had planned to participate in Tokyo and Hong Kong but has decided to fly home to recover prior to beginning her preparations for 2026.
Her upcoming training are set to feature coach Francisco Roig, as both individuals will keep partnering in 2026.
She underwent blood pressure monitoring in her opening round against Ann Li in Wuhan and retired when trailing 6-1 4-1 on a day with extreme humidity.
She needed once more a doctor's assessment at this week's Ningbo Open, where she was defeated in three sets to local wildcard Zhu Lin in round one.
Raducanu was also moving noticeably restricted in the third set versus Zhu because of the lower back problem that has troubled her on several occasions in 2025.
Such performances followed a positive campaign, in which the player advanced into the international top 30 after a long gap for the first time since 2022, finished with a trio of defeats.
She held three match points then was defeated by Pegula in round three in last month's Beijing event.
She secured 28 victories during 2025 and made it to the semi-final round in Washington, but her standout performance was at the Miami event in March.
The British number one advanced to the quarters of a premier WTA event, overcoming Emma Navarro, the eighth seed during the tournament before losing in three sets to Pegula, ranked fourth.
Her coach was Mark Petchey as coach from the Miami event through Wimbledon, with Roig assuming the role ahead of the US Open.
The initial agreement with Rafael Nadal's former coach was until the end of the season but the partnership will continue, with a training block pencilled in in the coming months.
Raducanu told that a three-day test period with Roig after Wimbledon was like a "secret mission" as they aimed to maintain secrecy.
She nearly succeeded to defeating top-ranked Aryna Sabalenka at the first competition with Roig in Cincinnati during August.
The coach also accompanied Raducanu in New York, where she made the third stage before being beaten by Elena Rybakina, the 2022 Wimbledon winner.
