2018 ATP YEC: Zverev Stuns Djokovic To Win Biggest Title

Sascha Zverev defeated Novak Djokovic in straight sets 6-4 6-3 to win the Nitto ATP Finals in London, becoming the youngest player to win the ATP's year-end championship since Djokovic won the title in 2008.  21-year-old Zverev will end the year ranked at World #4, behind Djokovic at #1, Rafael Nadal at #2 and Roger Federer at #3. In the semifinals, Zverev defeated Federer 7-5 7-6(5). His win over Djokovic ended a 14-match winning streak the Serbian had against Top 10 players in 2018 and evened their career head to head at 2-all (his head-to-head with Federer is now 3-all).

Last year, Grigor Dimitrov beat David Goffin to win the 2017 ATP year-end championship. This win often presages  a quantum increase in success, but Dimitrov didn't have a great 2018 afterwards.
