Emma Raducanu ends the current season and has decided to continue with coach through next year.
The British player made it to the third stage in three Grand Slam tournaments Grand Slam events in the current campaign.
Britain's Emma Raducanu has pulled out of the last two tournaments in 2025 as a result of the illness that has affected her for the last week and a half.
The 22-year-old had planned to participate in events in Asia but chose to travel back to regain her health prior to beginning plans for the 2026 season.
Her upcoming training will involve her coach Francisco Roig, as the pair have decided to continue collaborating for the upcoming season.
Raducanu underwent blood pressure monitoring in her opening round with Ann Li in the Wuhan tournament and retired when behind 6-1 4-1 on an oppressively humid day.
She again required a visit from the doctor at the recent Ningbo Open, where she lost in three sets to local wildcard Zhu Lin in the first round.
Raducanu was also moving with clear difficulty in the deciding set versus Zhu owing to back discomfort that has troubled her during parts of the season.
These outcomes followed a positive campaign, in which Raducanu rose into the international top 30 after more than three years in more than three years, ended with three successive defeats.
She held three match points before losing to Pegula in round three in Beijing last month.
She secured twenty-eight matches in the current season and advanced to the semis in the Washington tournament, but the highlight of her season was at the Miami Open in March.
As Britain's top player made the last eight of this WTA 1000 tournament, beating eighth seed Emma Navarro en route before losing in a three-set match to the world number four Pegula.
She worked with Mark Petchey from Miami until Wimbledon, with Roig taking over for the US Open.
The original arrangement with the former trainer of Nadal was until the end of the season but they will keep working together, with a training block pencilled in for the end of the year.
She mentioned that the trial session alongside Roig after Wimbledon was like a "secret mission" as they tried to keep the meeting secret.
She came very close to overcoming Sabalenka, the world number one at their initial event as a team in Cincinnati during August.
Roig joined her in New York, where she made the third stage then falling to Elena Rybakina, the 2022 Wimbledon winner.
