Novak Djokovic had some points with the serve clock throughout his Wimbledon remaining match on Sunday, and at one level he expressed his frustration to chair umpire Fergus Murphy.
Djokovic acquired a time violation warning throughout his second-set tiebreak towards Carlos Alcaraz. He was visibly irritated with the choice. Many felt the warning was overdue, as Djokovic had been utilizing the utmost 25 seconds (and presumably then some.)
Djokovic then complained to Murphy in regards to the serve clock throughout the third set. It appeared Djokovic thought Murphy was beginning the clock too rapidly and never giving him sufficient time to retrieve a towel between serves.
