Watson advances in Miami as Nadal quits
Britain’s Heather Watson battled back from a set down to reach the fourth round of the Miami Open.
Watson beat the Belgian world number 47 Yanina Wickmayer 3-6 7-5 6-3 and next faces fifth seed Simona Halep.
The British number two saved five break points across her final two service games in the second set to level the match and took control in the decider.
In the men’s draw, Rafael Nadal retired when losing 2-6 6-4 3-0 in his second-round match against Damir Dzumhur.
The Spaniard seemed to be struggling in the oppressive humidity and did not appear be injured when he quit.
It is the first time he has retired from a match since the 2010 Australian Open quarter-final against Britain’s Andy Murray.
