If Juan Martin del Potro played like this more often, tennis’ Big Three would be a Big Four (or, depending on your view of Andy Murray, a Big Five).
The big man from Argentina is playing tremendous defense against Roger Federer in the French Open quarterfinals, repeatedly chipping back to Federer’s backhand, keeping the ball in the court, then eventually setting up his monstrous forehand. As a result, he just took a 6-3, 7-6 lead over the 2009 French Open champion.
Juan Martin del Potro’s ceiling is higher than anybody outside of the world’s top three, and he is showing it at the moment. His size allows him to pummel flat forehand winners out of normal rallies, and while his movement and defense have not always been world class, everything is working at the moment.
