WIMBLEDON, England — The spotlight on the Australian tennis player Nick Kyrgios, whose confrontations with opponents and Wimbledon officials have made his matches can’t-miss theater for the past week, grew hotter Tuesday when news emerged that the police have begun legal proceedings against him for assaulting a former girlfriend in December.
The accusations landed on the eve of one of his most important matches, a quarterfinal showdown with Cristian Garín of Chile that he is favored to win, and less than 24 hours after he survived a five-set challenge from the American Brandon Nakashima on Monday.
