ATP World Tour: Top 5 Players On Tour

#4 Juan Martin del Potro

Del Potro is back in business!

Juan Martin del Potro certainly is back!

The Argentine has had quite the rollercoaster ride over the last few years.

A number of wrist injuries have haunted the world number four from continuing to compete at the top for all the titles on offer.

Del Potro once revealed that he nearly retired from the sport because of the never-ending spell of injuries.

But the 30-year-old's determination and can-do attitude has kept his belief strong that he can still compete against the best in the business.

His highlight of 2018 so far was reaching the US Open final which saw Del Potro finish runner-up to Novak Djokovic in three sets.

But another moment for Del Potro to remember was defeating Roger Federer at this year's Indian Wells Masters.

Del Potro also won the Mexican Open back in March.
