 In the final, Rafael Nadal defeated Novak Djokovic 6–4, 6–3, 2–6, 7–5 to win the match.
 It was a Major final match of historic proportions, as Rafael Nadal was looking to become the first man to win seven French Open titles, thus breaking the record previously held by Björn Borg, who won six titles, and equalling the record held by Chris Evert, who won seven titles, whilst Novak Djokovic was looking to become the first man since Rod Laver in 1969 to hold each of the four Major titles simultaneously.
 As well, Djokovic had defeated Nadal in the previous 3 Grand Slam finals and Nadal was trying to avoid coming runner-up in all 4 tournaments to the same player.
The 2014 Rafael Nadal tennis season officially began on 30 December 2013 with the start of the 2014 Qatar ExxonMobil Open.
 This season saw Nadal suffer from injuries that included a back injury, a wrist injury, and appendicitis.
 After losing in the final of the Australian Open where he suffered from a back injury, Nadal failed to defend his titles at Indian Wells, Barcelona, and Rome.
 He rebounded by claiming his 9th French Open.
 Prior to the North American hardcourt season, Nadal would experience another injury, this time a wrist injury which forced him to withdraw from the Rogers Cup, the Western & Southern Open and the US Open where he was the defending champion.
 Nadal announced on 24 October that he would not be competing for rest of the season due to appendicitis and eventually underwent surgery.
 Despite an injury plagued season, Nadal still ended the year at No. 3 with 4 titles.

 He recovered from his loss with three consecutive titles at the ABN AMRO World Tennis Tournament, the Dubai Duty Free Tennis Championships, and the BNP Paribas Open.
 He won his fourth title at the Mutua Madrid Open on blue clay, becoming the only person to win a title on blue clay in ATP history.

 Kyrgios is the second player after fellow Aussie Lleyton Hewitt to beat Roger Federer, Rafael Nadal and Novak Djokovic in their first meeting.
 He has been controversial at times, for example admitting in 2017 that he had "probably" tanked at eight tournaments during his professional career, because on certain days he’d "rather be doing something else than play tennis".
