Juan Martin del Potro retires with unique winning record against the Big Three

Although tennis star Juan Martin del Potro hung up his racket over a year ago, the Argentine officially called it a career after participating in one last exhibition match against 24-time Grand Slam champion Novak Djokovic.

A force to be reckoned with during his prime, del Potro shocked the tennis community when he upset Roger Federer to win the 2009 US Open title. The Tandil native would win 22 ATP titles during his career, and break into the top 5 on the ATP rankings, reaching a career-high of World No.3.

During an era when players feared facing Roger Federer, Rafael Nadal and Novak Djokovic, del Potro was one of the few who posed a threat to the Big Three. The Argentine racked up several wins against the three superstars, and in fact sits second on the list of players with most wins against the legendary trio with 17. Only former World No.1 Andy Murray has more wins against them (outside of the Big Three themselves), sitting atop the list with 29 wins.

Austrian Dominic Thiem, who also retired this year in front of his home fans at the Vienna Open, comes in third with 16 wins against the Big Three. Frenchman Jo Wilfried Tsonga shares the third spot with Thiem, as he also has 16 wins against the trio. Retired Australian Lleyton Hewitt rounds out the top five, as he has an impressive 14 combined wins against the Big Three of Federer, Nadal and Djokovic.
