The start of the Miami Open men's final between Novak Djokovic and unseeded 19-year-old Jakub Mensuk on Sunday at Hard Rock Stadium was delayed 5½ hours from its 3 p.m. start time.

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.

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.

The 24-time Grand Slam champion defeated Grigor Dimitrov 6-2, 6-3 in 71 minutes to advance to the Miami Open final and take a step closer to becoming the third-ever men's tennis player (Jimmy Connors, Roger Federer) to win 100 tour-level titles, a feat he can accomplish in Sunday's final.

Aryna Sabalenka of Belarus earned her first Miami Open championship by defeating American and No. 4 Jessica Pegula 7-5, 6-2 to become the sixth player to win Miami as the reigning No. 1. Former great Serena Williams did it four times.

Top-seeded Aryna Sabalenka recorded 31 winners while sailing to a 7-5, 6-2 victory over fourth-seeded Jessica Pegula on Saturday to win the Miami Open for the first time in her career. Sabalenka, ranked No. 1 in the world, saved 7 of 11 break points while winning her 19th career title and eighth at the 1000 level.

Though Pegula has made three Miami Open semifinals in four years, she has never gotten this far. Now she goes for her fourth WTA 1000 (point) title.
