Novak Djokovic and Jakub Mensik embraced the Masters 1000 final with the biggest age difference in Miami. The 19-year-old Czech ousted the 37-year-old Serb 7-6, 7-6 in two hours and three minutes en route to his first ATP title!

Novak Djokovic fell in the final round of the Miami Open to 19-year-old Jakub Mensik in straight sets, 7-6, 7-6, on Sunday. Mensik, playing in his first final, earned his spot after defeating No. 3 seed Taylor Fritz in the semifinals and became the second-youngest champion in tournament history, per ATP Tour.

In Miami, he beat three Top 10 opponents—Draper, Djokovic, and Taylor Fritz—went seven for seven in tiebreakers, and showed off a serve that will be one of the most important weapons in men’s tennis for the next decade. Mensik later revealed he nearly withdrew from the Miami Open due to a knee injury before his first match.
