Novak Djokovic is finding a higher gear in South Florida after a sluggish start to 2025.

Djokovic, gunning for his seventh Miami Open title, dispatched American Sebastian Korda 6-3 7-6 (7-4) on Thursday in one hour 24 minutes in their quarter-final postponed from Wednesday night.

The former world No.1 will now face Bulgaria's Grigor Dimitrov in Friday's semi-final. Djokovic is 12-1 against the 33-year-old Dimitrov, who reached the tournament final last year.

Djokovic, who won all his of his titles at the tournament's previous venue at Key Biscayne, is hunting his 100th professional title.

"Overall I've been playing very well the entire week,'" Djokovic told Tennis Channel after the match.

"I'm getting great support ... I feel I have a really good chance to go all the way here.

"...I'm playing the best I have in some time."

The Czech squeaked out the tiebreaker and then stormed to a 4-0 lead in the second set to knock out the 20-year-old Frenchman.

The 54th-ranked Mensik hit 13 aces and a crosscourt forehand winner that ended the match in 75 minutes.

Mensik will face third-seeded Taylor Fritz after the American squeaked out a two-hour 44-minute marathon over No.29 Matteo Berrettini 7-5 6-7 (7-9) 7-5.

Fritz squandered six match points in the second set against the Italian, including in the tiebreaker, but survived in the third set to make his first Miami Open final.

"Now I can sleep tonight and not worry about the chances I blew," said Fritz, who lives in Miami.

"You have two options ? one of them is to regroup.'"
