Emma Raducanu said she “did not feel anxious” on the court as she returned to action for the first time since dealing with a stalker at the Dubai Open last month. The 22-year-old was beaten in straight sets by Japan’s Moyuka Uchijima in the first round of Indian Wells amid extra security in California.

Raducanu, who was ousted in the first round at Indian Wells, regained her footing against Ishii as she won 77 per cent of her first-serve points, fired down six aces and converted five of her six break point chances in the 65-minute match.

Emma Raducanu drilled six aces while recording a 6-2, 6-1 victory over wild card Sayaka Ishii in the first round of the Miami Open on Wednesday. Raducanu converted 5 of 6 break points while defeating the 19-year-old from the Japan in just 65 minutes.
