Being an ATP Finals champion still seems a bit unreal to Greek tennis star Stefanos Tsitsipas as the 21-year-old is now set to take a deserved break before he kicks off his preparation for the next season. Tsitsipas, ranked at No.
6 in the world, edged out fourth-ranked Austrian Dominic Thiem in a thriller final at The O2 Arena to claim the biggest title of his short career. The Greek blew an early third set break but delivered in the tie-break later in the set to earn a 6-7 (6) 6-2 7-6 (4) win over back-to-back French Open runner-up Thiem.
Tsitsipas, who achieved a career-high ranking of No. 5 this year, made six finals this year and claimed titles on three occasions. "Still seems unreal that I am holding this (ATP Finals) trophy - didn’t want to let it go but now it’s time for some holiday adventures and wanted to thank everyone that has helped me get where I am today because it has been a team effort.
London - you seduced me and part of my heart is yours so please be gentle with it," Tsitsipas said in an Instagram post.
