#9 Lowest ranked player to take the year-end No.1 ranking
Following an injury-affected 2017 season which saw Djokovic (22) slip out of the top 20 of the world rankings for the first time in more than a decade, the Serb reeled off title runs at Wimbledon, Cincinnati, US Open, Shanghai and Paris Bercy to seal a stunning return to the No. 1 of the world rankings.
In the process, Djokovic moved level with Jimmy Connors and Roger Federer with 5 year-end No. 1 finishes, which is just one shy of Pete Sampras' record of 6.
#10 First Wimbledon winner in the Open Era to save championship points
In a pulsating five-set 2019 Wimbledon final, Djokovic squandered a 4-2 lead in the fifth set to stare down two consecutive championship points on Federer's serve at 7-8 15-40.
However, four points later it was 8 games all as Djokovic saved both match points, repeating his feat from the 2010 and 2011 US Open semifinals.
Surviving another attack on his serve at 11-11, the Serb prevailed in a historic first-ever Wimbledon final to feature a 5th set tiebreak. In the process, he became the first player since Bob Falkenburg beat John Bromwich (1948) to win Wimbledon after facing multiple championship points.
