Emma Raducanu wraps up her season and will keep trainer for 2026.
The British player made it to the third stage in three of the four major tournaments in the current campaign.
Britain's Emma Raducanu has withdrawn from her remaining competitions in 2025 due to a medical condition that has affected her over the past 10 days.
Raducanu, aged 22 was scheduled to compete in Tokyo and Hong Kong but opted to return home to regain her health prior to beginning plans for the 2026 season.
Her upcoming training will involve her coach Francisco Roig, as they have decided to continue collaborating again next season.
The tennis professional underwent blood pressure monitoring while playing the initial match with Ann Li in Wuhan and retired when losing 6-1 4-1 on a day with extreme humidity.
She again required a doctor's assessment at this week's Ningbo Open, where she lost in three sets to Zhu Lin, a Chinese wildcard in the first round.
Raducanu was also moving noticeably restricted in the final set in the match with Zhu owing to a lower back issue that has troubled her during parts of the season.
These outcomes signaled a promising season, in which the player advanced into the world's top 30 for the first time in more than three years, concluded with three straight losses.
Raducanu had three match points then was defeated by Pegula in round three in Beijing last month.
The player achieved 28 matches this year and advanced to the semis in Washington, but her standout performance was at the Miami Open in March.
Ranked first in Britain advanced to the quarters of this WTA 1000 tournament, overcoming Emma Navarro, the eighth seed on the way before losing in three sets to fourth-ranked Pegula.
Her coach was Mark Petchey between Miami and Wimbledon, with Francisco Roig stepping in in time for the US Open.
The original arrangement with Rafael Nadal's former coach was for the remainder of the year but the collaboration persists, with a training block pencilled in late this year.
Raducanu told that her three-day trial with Roig post-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 August's Cincinnati tournament.
Roig joined her in New York, where she advanced to round three prior to losing to Elena Rybakina, the 2022 Wimbledon winner.
