Defending Wimbledon champion Carlos Alcaraz was given another tough litmus test by plucky German Jan-Lennard Struff but the second seed battled his way to a 6-1 3-6 6-3 6-4 victory and reached the fourth round on Friday.

Alcaraz's tennis is so often a highlight reel but on grass, he does his most devastating work in the negative spaces of points.

Cam Norrie and Sonay Kartal are the only British hopes left standing at Wimbledon after an emotional exit for Emma Raducanu. She had her chances against world No.1 Aryna Sabalenka, but in both sets, she was unable to capitalise on breaks of serve as she went down 7-6, 6-4.
