Katie Boulter says she is not feeling any pressure as she battles to keep the British number one ranking with Emma Raducanu and Sonay Kartal closing in.
Boulter, 28, has been the nation's leading women's player since June 2023, but has dropped down the world rankings in a stop-start season.
Having reached a career high 23rd in November, Boulter is now 40th after winning five of her 10 matches this year.
Raducanu is up to 49th after reaching the Miami quarter-finals last month, while Kartal's rapid rise has continued and moved her up to 60th.
