#3 Novak Djokovic (57-11)

Novak Djokovic

Novak Djokovic opened the season with a straight-sets win over Rafael Nadal to become the first seven-time winner at the Australian Open. On the clay of Madrid, Djokovic overcame Nadal's semifinal conqueror Stefanos Tsitisipas in the semis to win his 33rd Masters 1000 title, before losing to Nadal in a three-set Rome final a week later.

Djokovic's five-set defeat to Dominic Thiem in the Roland Garros semis ended the Serb's hopes of winning a non-calendar year Slam for the second time in his career.

Djokovic then proceeded to the grasscourts of Wimbledon, where he beat first-time Slam finalist Roberto Bautista Agut in four sets to reach his sixth final at the grass-court major.

In the longest-ever Wimbledon final, Djokovic led Federer by a set on two occasions before staring down two consecutive championship points on the Swiss maestro's serve at 8-7 40-15 in the fifth. Federer missed the first on a forehand error and when the Swiss served down the T and rushed the net, Djokovic laced an inch-perfect cross-court pass which tantalisingly eluded Federer's racquet.

Djokovic broke back and survived break points at 11-11 before beating the 20-time Grand Slam in a historic first-ever Wimbledon deciding set tiebreak. In the process, he became the first player in 71 years to win the tournament after saving multiple championship points.

Djokovic's title defence at the Cincinnati Masters ended in a three-set semifinal defeat to eventual winner Daniil Medvedev. Then another title defence, this time at the US Open, ended in the fourth-round where the Serb retired against Stan Wawnrika.

The 16-time Grand Slam winner won his first-ever title in Tokyo before losing to Stefanos Tsitsipas in the Shanghai quarterfinals. Djokovic registered his 50th win of the season at the Paris Masters en route to winning his 34th Masters 1000 title at the Paris Masters, slashing his deficit to Nadal in the race for the year-end no. 1 to 640 points.

However, at the season-ending ATP Finals, the Serb lost to Dominic Thiem in an epic third-set tiebreak before losing to Federer for the first time in four years to make a group-stage exit. Djokovic's defeat confirmed Nadal as the 2019 year-end no. 1.
