Emma Raducanu faces testing time with high ranking under threat.

Emma Raducanu has endured a torrid time both on and off the court in recent months, tasting defeat in six of her last seven matches. The former US Open winner was beaten in the opening round at Indian Wells by Moyuka Uchijima earlier this month, and she will hope to get back on track in Miami.

Raducanu’s poor form has seen her slip down the WTA Rankings, falling from No. 55 to No. 60. Having reached the third round at Indian Wells last year, the defeat to Uchijima saw the Brit drop key ranking points.
