5 players who have made brilliant comebacks this year

#1 Juan Martin Del Potro

Del Potro's performance at the US Open helped him rise nearly 80 places to World No. 65

Delpo is gradually becoming tennis' comeback king after making a second successful comeback from a wrist injury. Earlier in 2010, Delpo had problems with his wrist and was out for several months before making a brilliant comeback in 2011.

However, in 2014, the Argentine had another wrist injury which kept him out of the game for nearly two years and by the time he came back to playing tennis, Del Potro was ranked 1042 in the world.

Del Potro's first signs of a successful comeback were shown at the Wimbledon where he stunned Stan Wawrinka in the second round. He then put up a marvellous performance at the Rio Olympics where he stunned World No.1 Novak Djokovic in the first and round and Rafael Nadal in the semi-finals to set up a gold medal match with Andy Murray which he eventually lost, thus winning the silver medal.

His brilliant performances earned him a wildcard to the US Open by the time of which Del Potro was ranked 144th in the world. The Argentine began the tournament very well, winning his first three matches in straight sets which also included a win against David Ferrer.

In the fourth round, his opponent retired which allowed Del Potro to advance to the quarter-finals where eventual champion Stan Wawrinka avenged his Wimbledon defeat by beating Delpo in four sets. Del Potro's performance at the US Open helped him rise nearly 80 places to World No. 65.

Truly, the comeback of the year and one of the greatest in tennis history.
