(Main article: 2013 Wimbledon Championships) Roger Federer was the defending champion but lost in the second round to World No. 116 Sergiy Stakhovsky in a massive upset. Stakhovsky was unable to build on his effort and lost in the next round in 4 sets to Jürgen Melzer. Federer's loss marked the first time since the 2004 French Open, when he lost to Gustavo Kuerten in the third round, that he had failed to reach at least the quarterfinals in a Grand Slam event. It was also Federer's earliest exit in this tournament since 2002, and the first time that Federer lost to a player ranked lower than 100 since his loss to then World No. 101 Richard Gasquet at the 2005 Monte Carlo Masters.
