Carlos Alcaraz reaches Wimbledon quarter-final despite issues with serve

Reigning Wimbledon champion Carlos Alcaraz was broken five times by Ugo Humbert but regrouped to book a place in the quarter-finals.

Alcaraz had spent nearly four hours on court during a dramatic victory over Frances Tiafoe on Friday and looked in a hurry to progress when he raced into a two-set lead.
