11:15 a.m.

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.
