Raducanu advanced to round three in three of the four major tournaments this year.
Britain's Emma Raducanu will not compete in her final two events in 2025 due to the illness she has been battling for the last week and a half.
The 22-year-old was scheduled to compete in events in Asia but chose to travel back to recover ahead of launching plans for the 2026 season.
Those preparations will involve coach Francisco Roig, as both individuals will keep partnering for the upcoming season.
Raducanu had her blood pressure taken in her opening round versus Ann Li in the Wuhan tournament and stopped playing when losing 6-1 4-1 on a very muggy occasion.
She needed once more a visit from the doctor at the recent Ningbo Open, where she lost in three sets to Chinese wildcard Zhu Lin in the opening round.
She was also playing far from freely in the final set against Zhu because of a lower back issue that has affected her at times this year.
These outcomes signaled a promising season, in which the player advanced into the international top 30 after more than three years for the first time since 2022, concluded with three straight losses.
Raducanu had three match points then was defeated by Jessica Pegula in the third round in last month's Beijing event.
Raducanu won twenty-eight matches this year and advanced to the semis in Washington, but her most impressive week was at the Miami Open in March.
The British number one made the last eight of a premier WTA event, overcoming Emma Navarro, the eighth seed during the tournament before losing in a three-set match to fourth-ranked Pegula.
She worked with Mark Petchey from Miami until Wimbledon, with Roig assuming the role ahead of the US Open.
The initial agreement with Rafael Nadal's former coach was for the remainder of the year but the partnership will continue, with a training block pencilled in late this year.
Raducanu told that a three-day test period with Roig after Wimbledon was like a "black ops mission" as the meeting was kept under wraps.
She nearly succeeded to overcoming Sabalenka, the world number one at the first competition with Roig in Cincinnati in August.
The coach also accompanied Raducanu in the New York tournament, where she made the third stage before being beaten by 2022 Wimbledon champion Elena Rybakina.
