Del Potro is primarily an offensive baseliner with a powerful serve and deep, flat/topspin groundstrokes. His forehand shot is one of his main strengths, capable of generating speeds over 100 mph, and he also possesses a very consistent and powerful double-handed backhand. Despite his height, del Potro is considered one of the best movers on the ATP tour, able to move efficiently on various surfaces like clay and hard courts. Del Potro's height allows him to get a powerful first serve, and makes it easier for him to return high topspin balls. Del Potro's best surfaces are hard and clay, while his game on grass has yet to improve with his height being cited as a possible factor.
