Djokovic becomes the oldest Masters semi-finalist in Miami history

Novak Djokovic showcased his exceptional skills to secure a spot in the semi-finals of the Miami Open, achieving a notable victory over American Sebastian Korda with a score of 6-3, 7-6 (7/4). This win makes him the oldest player to reach a Masters 1000 semi-final.

The 37-year-old Serbian athlete began the match with a strong performance, breaking Korda early and maintaining his lead throughout the first set. However, Korda demonstrated remarkable determination in the second set, pushing the match into a tie-break.

Despite this challenge, the fourth seed, who is aiming for his seventh Miami Open title and his first since 2016, responded decisively, clinching the match with a powerful ace.

Djokovic, set to compete against Bulgarian Grigor Dimitrov on Friday, attributed his success to his impressive first-serve performance, winning 84 percent of those points.

"One word - serve. I was serving very well, probably the best serving performance, not just here, but in a long time," he told reporters.

"11 aces, when I needed to find the first serve. It makes life easier on the court when you are feeling your serve. I needed it in the second set when I think Korda was feeling his ground strokes much better," said Djokovic.

A victory at Miami would be a landmark 100th singles title for the 24-times Grand Slam champion and he said is glad to be refinding a top level.

"I am obviously playing the best tennis I have played in quite some time. It’s great when I experience tournaments like this and performances like this it motivates me and encourages me to keep going for more," he said.

Czech teenager Jakub Mensik advanced to his first Masters semi-final by overcoming France's Arthur Fils with a score of 7-6(5), 6-1.

Fils had celebrated one of the most significant victories of his career on Wednesday by defeating top seed Alexander Zverev; however, he found it challenging to replicate that success against the formidable 19-year-old Mensik.

The powerful serve of the tall Czech proved to be overwhelming for Fils, who had previously endured three-set matches against Frances Tiafoe and Zverev, displaying signs of fatigue.

"It feels incredible. I think the biggest result so far in my career, so I'm glad I just kept going since the first round," said Mensik.

"That's the key, to keep the focus during the two weeks, because it's always tough. The job is not done."

Mensik established an early advantage with a 4-1 lead, but allowed Fils, the 20-year-old French player, to level the match, resulting in a tie-break.

After overcoming Fils' resurgence, Mensik displayed remarkable composure in the second set, ultimately securing his victory in just 75 minutes.

Currently ranked 54th in the world, Mensik is set to compete against the winner of the quarter-final match between Taylor Fritz and Matteo Berrettini later on Thursday.
