Jakub Mensik is a Masters 1000 champion! The young Czech prevailed over Novak Djokovic 7-6, 7-6 in two hours and three minutes in the Miami Open final for his first ATP title. Thus, Mensik became the first player born in 2005 with a Masters 1000 crown.

After a surprising week in Miami, where Jakub Mensik emerged victorious, here are the biggest changes in the ATP rankings.

Jakub Mensik denied Novak Djokovic his 100th tour level title as he claimed his first in a rain-delayed Miami Open final. The 19-year-old Czech won 7-6 (4) 7-6 (4) as he won his first ATP Masters 1000 final and became the second-youngest Miami champion behind Carlos Alcaraz, who won in 2022 as an 18-year-old.
