After a two-week break Novak entered the Wimbledon Championships, where he played much better than in the previous tournaments on clay. He reached the final without dropping a set in the first five matches and won a tight meeting with del Potro, the meeting lasting almost five hours and being the longest semifinal in Wimbledon history. However, two days later Djokovic was not able to threaten Murray despite leading in the second and third set and having saved three championship points. He lost in straight sets, for the first time since 2010. Novak then started a four-week break and started the North American Hard Court season at the beginning of August, aiming to stay at the top of ATP Ranking. At the Rogers Cup, he came attempting to win his third consecutive Canadian Open at the Montreal edition. Although he defeated Gasquet in a rematch of the 2012 final in what he called almost perfect play, he lost a close 7–6 third set tiebreak to nemesis Rafael Nadal in the semis, ending his hard court winning streak against Nadal. Djokovic reached the quarterfinals at Cincinnati but lost to Isner 7–5 in a third set. Djokovic then lost in the US Open final in four sets to Nadal. Since then Djokovic won Beijing against Nadal in straight sets, Shanghai against del Potro and Paris against Ferrer. At the ATP World Tour Finals, Djokovic retained the trophy, beating Nadal in straight sets.
