BREAKING NEWS - Rio 2016: Djokovic falls to Del Potro


World number one Novak Djokovic was dumped out of the men's singles tournament at Rio 2016 in the first round as Juan Martin Del Potro's resurgence continued.

Fit again after being badly hampered by wrist problems in recent years, Del Potro provided one of the feel-good stories of Wimbledon by knocking out fourth seed Stan Wawrinka in round two. 

And the powerful Argentinian was able to spring another surprise on Sunday, beating Djokovic 7-6 (7-4) 7-6 (7-2), with the aid of 41 winners.

Del Potro had also triumphed over Djokovic in the bronze medal match at London 2012.
