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!

Heavy rain poured down on Hard Rock Stadium Sunday afternoon and there was lightning in the area, delaying the start of the Miami Open men’s final between 24-time Grand Slam champion Novak Djokovic and 19-year-old Czech newcomer Jakub Mensik.

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.
