Emma Raducanu made it to the third stage in three of the four Grand Slam events during the season.
Britain's Emma Raducanu has pulled out of her final two events in 2025 due to the illness she has been fighting in recent days.
At 22 years old was scheduled to compete in Tokyo and Hong Kong but has decided to fly home to rest and recuperate before starting her preparations for 2026.
Her upcoming training are set to feature trainer Francisco Roig, as they will keep partnering in 2026.
Raducanu required blood pressure checks in her opening round with Ann Li in Wuhan last week and stopped playing when trailing 6-1 4-1 on an oppressively humid day.
She again required a doctor's assessment at the Ningbo Open this week, where she lost 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 back discomfort that has troubled her at times this year.
Such performances followed a positive campaign, in which Raducanu rose into the top 30 globally after more than three years in more than three years, finished with a trio of defeats.
Raducanu had three match points prior to falling to Jessica Pegula in the third stage in the Beijing tournament last month.
Raducanu won twenty-eight matches this year and advanced to the semis in Washington, but her standout performance was at the Miami event in March.
As Britain's top player made the last eight of this WTA 1000 tournament, beating eighth seed Emma Navarro during the tournament then falling in three sets to fourth-ranked Pegula.
Her coach was trainer Mark Petchey from Miami until Wimbledon, with Francisco Roig stepping in in time for the US Open.
The original arrangement with the ex-coach of Rafael Nadal was through the season's conclusion but the partnership will continue, with a training session scheduled in the coming months.
Raducanu told that the trial session alongside Roig after Wimbledon was like a "covert operation" as they tried to keep the meeting secret.
She came very close to beating world number one Aryna Sabalenka at the first competition with Roig in August's Cincinnati tournament.
Roig joined her in the New York tournament, where she made the third stage before being beaten by Elena Rybakina, the 2022 Wimbledon winner.
