Action got underway at the All England Tennis club with a startling upset on the women's side. Among the men, world number one Novak Djokovic, bidding for a Grand Slam, easily won his opening match.
The world's top-ranked men's tennis player, Novak Djokovic, jumped all over his British opponent James Ward, winning the first set to love. Djokovic opened the second with a service break as well, but Ward fought back, taking the set to a tie-breaker.
Djokovic won that affair 7-3 before prevailing by a single break in the third set. The 6-0, 7-6, 6-4 victory sends the Serb, who's on a quest to win all four tennis majors in a calendar year, into the next round of Wimbledon 2016.
