Djokovic struggles in rain
Novak Djokovic had to come from a set down to beat Italy's Fabio Fognini on a frustrating day of Olympic tennis at Wimbledon.
Heavy showers throughout the day prevented all but a couple of hours of play on any court except Centre, and Djokovic on Court One was among those badly affected.
The second seed, who carried Serbia's flag in the opening ceremony, looked uncomfortable with his footing on the grass but eventually won a rain-interrupted match 6-7 (7/9) 6-2 6-2 victory to set up a second-round clash with either Andy Roddick of the US or Slovakia's Martin Klizan.
Under the roof on Centre Court, fifth seed Jo-Wilfried Tsonga also struggled, eking out a 6-7 (5/7) 6-4 6-4 victory.
Fourth seed David Ferrer of Spain had a easier time against Canada's Vasek Pospisil, winning 6-4 6-4, while Japanese 15th seed Kei Nishikori defeated Australia's Bernard Tomic 7-6 (7/4) 7-6 (7/4). Play was officially called off for the night just after 8pm with only six men's matches completed all day.
