#4 Juan Martin Del Potro
Very few players have the capability to bounce back strongly from an injury but the 2009 US Open champion Juan Martin Del Potro has done this twice, after previously being out of action in 2010 owing to a wrist injury.
After a silver medal performance at the Rio Olympics where he beat Rafael Nadal and Novak Djokovic, ‘Delpo’ has had a brilliant US Open so far.
In the first round, Del Potro beat compatriot Diego Schwartzman in straight sets before beating the highest ranked American Steve Johnson in similar fashion to set up a third round encounter against David Ferrer.
What was expected to be a close contest at the end of the first set, soon turned out to be a one-sided affair as Del Potro’s offensive game eventually got the better of the 11th seeded Spaniard in straight sets. He next faced Roland Garros semifinalist Dominic Thiem and was looking in command before the Austrian retired during the second set owing to an injury concern in his right knee.
Del Potro will now face two-time semi-finalist Stanislas Wawrinka in the quarter-finals, whom he beat a couple of months back at Wimbledon. In current form, there is a very good chance that he might make it to the semi-finals of the US Open, for the first time since his victorious 2009 campaign.
