The Latest from Wimbledon (all times local):
Victoria Azarenka is the first player to reach the second round of Wimbledon.
The 23rd-seeded Belarussian, a two-time Australian Open champion, beat Anett Kontaveit of Estonia 6-2, 6-1 on Court No. 12.
Nick Kyrgios hit it right on the head -- on the head of a linesman, that is.
The 26th-seeded Australian was hitting back to the ball boy during his opening match at Wimbledon on Monday when he sent an errant shot toward the corner of the court that bounced off the top of the head of an unsuspecting linesman.
The linesman wasn't hurt, and he and Kyrgios soon shared a laugh with the crowd. The linesman then wiped his brow and Kyrgios got back to work against Diego Schwartzman, jumping out to a 6-0, 6-2 lead.

Rain shouldn't be problem on the opening day at the All England Club.
Play has already started at Wimbledon, with some sun sneaking through the gray clouds overhead.
The dry weather and warm temperatures are expected to stay well into the first week.
Day 1 at Wimbledon is upon us, and Novak Djokovic is first up on Centre Court.
The defending champion from Serbia will take to the grass at about 1 p.m., but it will be no walk in the park against Philipp Kohlschreiber of Germany.
Djokovic won his second title at Wimbledon last year, beating seven-time champion Roger Federer in five sets. The two could meet in the final again this year.
Stan Wawrinka, who beat Djokovic this month in the French Open final, is also scheduled to play on Centre Court, taking on Joao Sousa of Portugal.
In the women's draw, top-seeded Serena Williams will continue her bid for a true Grand Slam by taking on Margarita Gasparyan of Russia on Court No. 1. Maria Sharapova, the 2004 champion at the All England Club, will be up against Johanna Konta of Britain in the main stadium.
