Wimbledon Tennis: Kerber, Djokovic, Federer All Progress To Next Round
There can be few things in Tennis more embarrassing than being beaten in the first round of a grand slam tournament while ranked number one in the world.
It is a painful memory that is still fresh in Angelique Kerber's mind, having suffered that misfortune at the French open just five weeks ago.
Luckily for her she proved the naysayers wrong with her 6-4 6-4 win over American qualifier Irina Falconi.
Later, Wimbledon fans with centre court tickets suffered the disappointment of seeing the opponents of title contenders Roger Federer and Novak Djokovic retire early in their matches.
Second seed Djokovic advanced after Martin Klizan gave up after 40 minutes when 6-3 2-0 down.
Seven-times Wimbledon champion Federer led 6-3 3-0 when Ukrainian Alexandr Dolgopolov withdrew with an ankle injury after 43 minutes.
Earlier, Dominic Thiem beat Vasek Pospisil 6-4 6-4 6-3.
The 23-year-old Austrian, world number eight in the world, faces Frenchman Gilles Simon in the second round.
