Jessica Pegula stopped the string of upsets at the Miami Open by ending the stalwart run of Britain's unseeded Emma Raducanu on Wednesday night.

Emma Raducanu fought back from the brink to seal her first win against a top-10 opponent in eight months by beating Emma Navarro in three sets at the Miami Open. Raducanu, world number 60, was a point away from trailing 4-1 in the final set and overcame fatigue to win a titanic struggle 7-6 (8) 2-6 7-6 (3) against eighth-seeded American Navarro.
