Teen’s wild revelation after beating Djokovic in historic Miami Open upset win

A teen has stunned Novak Djokovic to win the Miami Open, before making a shock revelation that made the upset more impressive.

Czech teenager Jakub Mensik has upset Novak Djokovic 7-6 (7-4), 7-6 (7-4) to win the Miami Open at Hard Rock Stadium on Monday (AEDT).

The 19-year-old, ranked 54th in the world, claimed his first title on the ATP Tour and denied Djokovic his 100th professional title.

The final was delayed by almost six hours due to heavy rain and when the players emerged it was clear that Djokovic had an eye infection.

Mensik started strongly breaking Djokovic’s first serve game to go 2-0 up and the tall, big-serving Czech was dominating until, at 4-2 Djokovic broke back when Mensik found the net.

The set remained on serve from then on, but in the tie-break Mensik’s powerful serve, with two aces, put him in charge from the outset.

He opened up a 5-0 lead and although Djokovic fought back the youngster sealed the set with an overhead volley.

It was the first set that Djokovic had lost in the entire tournament.

The second set was a nip and tuck affair with neither player able to break. Once again Mensik’s power proved decisive in the tie-break and when Djokovic went long on a return to hand him victory he fell to his back.

The match between the 37-year-old Djokovic and Mensik was the biggest age gap difference in a Masters 1000 final and the biggest age gap of any tour-level since 1976.

At 19 years and 201 days old, Mensik is the fifth youngest ATP 1000 Masters champion, behind only Michael Chang, Rafael Nadal, Carlos Alcaraz and Holger Rune.

Not a bad first career title for Jakub Mensik. Has a huge game 😤

54 - Jakub Mensik (#54) is only the second player ranked outside the ATP’s top 50 to defeat Novak Djokovic in an ATP event final after Stan Wawrinka (#69), who achieved the feat in Djokovic’s second career final (Umag 2006). Rare.#MiamiOpen | @MiamiOpen@atptour@ATPMediaInfo

Mensik won all seven tiebreakers he contested throughout the Miami Open.

Speaking at the post-match trophy presentation, Mensik revealed he nearly withdrew from the tournament before his first round match with a knee injury, but was able to get treatment from an ATP trainer that allowed him to play.

“One hour before my first match in Miami I was signing the paper to withdraw,” Mensik said.

“I was lucky the referee was at lunch. Then the physio did a miracle”.

“Novak, everyone knows you are the one,” Mensik said.

“When I was young I started to play tennis because of you.”

Mensik’s message written on the TV camera read “1st of many”, a sentiment Djokovic agreed with.

Djokovic was gracious in defeat, saying: “This is Jakub’s moment. Congratulations, unbelievable tournament. First of many.

“It hurts me to admit it but you were better. In the clutch moments, you delivered the goods.

“Unbelievable serving and phenomenal effort mentally to stay tough in the difficult moments.

“I wish you the best of luck and maybe you’ll let me win one of the next times we play.”
