Former US Open champion Juan Martin del Potro paid an emotional goodbye to tennis after a farewell exhibition match against Novak Djokovic in Argentina.
The 36-year-old won his sole major title in 2009 but his career was blighted by injuries.
The Argentine fractured his knee in 2019 - an injury that he says has left him with daily pain - and played his final match in 2022.
But he participated in 'The Last Challenge' in Buenos Aires against long-time rival and good friend Djokovic and about 15,000 watched Del Potro win 6-4 7-5.
