Emma Raducanu ends this year's campaign and plans to retain her coach through next year.

Her upcoming training will involve trainer Francisco Roig, as both individuals have decided to continue collaborating again next season.
Raducanu underwent blood pressure monitoring while playing the initial match against Ann Li in Wuhan and withdrew when behind 6-1 4-1 on a very muggy occasion.
She again required medical attention at this week's Ningbo Open, where she lost in three sets to Chinese wildcard Zhu Lin in the first round.
Her movement was with clear difficulty in the deciding set versus Zhu owing to the lower back problem that has affected her at times this year.

Her coach was Mark Petchey from the Miami event through Wimbledon, with Roig taking over for the US Open.
The first plan with Rafael Nadal's former coach was for the remainder of the year but the partnership will continue, with planned training sessions for the end of the year.
Raducanu told that a three-day test period alongside Roig after Wimbledon was like a "secret mission" as they aimed to maintain secrecy.

The coach also accompanied Raducanu in the New York tournament, where she advanced to round three before being beaten by Elena Rybakina, the 2022 Wimbledon winner.
