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.

Jakub Mensik outdueled Novak Djokovic in two tiebreakers 7-6 (4), 7-6 (4) to win the Miami Open for his first ATP title.

Jakub Mensik used his length to shrink the court, erasing Novak Djokovic's ability to find winners in a shock upset for his first career tennis title Sunday at the Miami Open. The No. 54 player in the world also denied Djokovic of his 100th career title and a record seventh Miami Open crown.
