Novak Djokovic first broke into the top 10 of the ATP rankings in March 2007, when he moved from No. 13 to No. 10. Since then, Djokovic has almost always been in the top 10, barring an eight-month period during 2017-18 when he was injured.The World No. 1's prolonged dominance during his tenure as a top-10 player means that he owns several records in that aspect.On that note, here's a look at three of the most impressive records owned by Djokovic as a top-10 player:#1 Novak Djokovic has the highest win percentage among active playersNovak Djokovic's win-rate as a top-10 player is currently 85.4% which is the highest among players with a minimum of 100 wins. Djokovic has won 882 matches and lost 151 as a top-10 player.The Serb leads long-time rivals Roger Federer and Rafael Nadal, who occupy the second and third spots respectively. Federer's win-rate as a top 10 player is 85.1%, while Nadal's is slightly lower at 84.5%.#2 Novak Djokovic has the highest win percentage against fellow top-10 playersNovak Djokovic after beating Alexander Zverev at the 2021 US OpenDuring his stint as a top-10 player, Novak Djokovic has faced another player ranked in the top 10 on 305 occasions.
