There was a surprising and heartwarming moment at the end of Novak Djokovic's victory over his Bolivian opponent Hugo Dellien as he was asked for his shirt.
The world number one overcame Dellien in straight sets to secure his place in the second round in just over an hour.
Djokovic was relatively untroubled against the world number 72, who failed to win a single break point and he bowed to each empty stand at the end of the match.

Djokovic is bidding to become only the second tennis player in history to complete the ‘Golden Slam’; to win all four major titles and an Olympic gold in the same year.
Steffi Graf remains the only player to achieve the feat, winning the Australian Open, the French Open, Wimbledon, the US Open and then Olympic gold at Seoul in 1988.
