Czech teenager Jakub Mensik upset Novak Djokovic 7-6 (7/4), 7-6 (7/4) to win the Miami Open at Hard Rock Stadium on Sunday.
The 19-year-old, ranked 54th in the world, claimed his first title on the ATP Tour and denied Djokovic his 100th professional title.
The final was delayed by almost six hours due to heavy rain and when the players emerged it was clear that Djokovic had an eye infection.
Mensik started strongly breaking Djokovic's first serve game to go 2-0 up and the tall, big-serving Czech was dominating until, at 4-2 Djokovic broke back when Mensik found the net.
