At Wimbledon, Del Potro won against Albert Ramos, Jesse Levine, and Grega Žemlja before advancing past the fourth round for the first time in his career, thanks to a win over Andreas Seppi. He then played David Ferrer and, despite slipping badly during the fifth point of the match and aggravating a pre-existing leg injury, requiring over five minutes of treatment and by his own admission being close to forfeiting the match, he recovered to defeat Ferrer in straight sets to advance to his first Grand Slam semifinal since the 2009 US Open without dropping a set. On 5 July, Djokovic defeated him in five sets in 4 hours and 43 minutes, making it the longest semifinal in the history of Wimbledon men's singles.
