Emma Raducanu is through to her first WTA 1,000 quarter-final after a blistering straight-set win over 17th seed Amanda Anisimova in Miami.

Emma Raducanu said she had rediscovered her competitive spirit at the Miami Open this week after the Briton won four WTA main draw matches in succession for the first time since her U.S. Open triumph in 2021.

Anisimova had developed a deep blister on the middle finger of her right hand during her previous match – a near-three-hour epic against Mirra Andreeva on Sunday evening. Against Raducanu on Monday, she also needed treatment at the end of the first set for a wrist problem, having strapping applied to the joint.

Australian Open champion Madison Keys suffered a shock 6-4, 6-2 defeat in the third round of the Miami Open to Filipina teenager Alexandra Eala.
