19:10 CET - The second semi-final is between world number two Jannik Sinner and world number four Alexander Zverev. The Italian won the Miami title in 2024, while Zverev is a former finalist, having lost to John Isner in 2018.
Sinner is on a simply stunning run in Masters 1000 events. He has won a record 30 consecutive sets at this level, including title runs in Paris at the end of last year and Indian Wells a few weeks ago.
En route to the semis, he has beaten players like Corentin Moutet, Alex Michelsen and Frances Tiafoe. He now stands on the verge of becoming the eighth man to win the 'Sunshine Double' (winning both Indian Wells and Miami in the same season), and the first since Roger Federer in 2017.
Meanwhile, Zverev continues to show incredible consistency, regularly going deep in tournaments and reaching the final stages. However, he often falls short when coming up against Sinner and Carlos Alcaraz, but he has another chance here to prove he has the quality to mix it with those two.
The German has beaten the likes of Marin Cilic, Quentin Halys and Francisco Cerundolo to get here, losing just a single set against the former.
On paper, the head-to-head looks close between the pair, with Sinner winning seven and Zverev four. However, Sinner has won their last six meetings in a row, establishing a real dominance over his opponent. How can Zverev turn the tables today?
18:11 CET - The first semi-final is between Arthur Fils and Jiri Lehecka, and a win for either would be massive, as they would move into a first Masters 1000 final.
Lehecka has been in a 1000 semi-final once before in Madrid, but had to retire against Felix Auger-Aliassime at 3-3 in the first set. However, Fils has never reached this stage.
The Czech has dropped just one set en route to the semis, beating the likes of Taylor Fritz and qualifier Martin Landaluce.
Fils has had more of a tough time, needing three sets to get through Valentin Vacherot and Tommy Paul. He had to save four match points at 6-2 down in the final set tiebreak to see off the latter.
Fils leads the head-to-head 2-1, and won their last match-up in Doha a few weeks ago. Lehecka will be the fitter of the two, and that could be a deciding factor with Fils returning from a lengthy injury layoff recently.
17:00 CET - Welcome back to our live coverage of the Miami Open this evening, and by the end of play today, we will know who our men's finalists are!
The opening last-four clash gets underway at 20:00 CET, as Arthur Fils and Jiri Lehecka go head to head for a maiden appearance in a Masters 1000 final.
21-year-old starlet Fils' return from a lengthy injury layoff has been so impressive, and after an epic quarter-final win over Tommy Paul, he will have to find the strength to overcome Lehecka, who has had a slightly easier route to this stage, beating qualifier Martin Landaluce in the last round.
The second semi-final sees world number two and heavy favourite to win the title, Jannik Sinner, go up against Alexander Zverev in a rematch of their recent Indian Wells meeting in the same round.
Sinner crushed Zverev in that match and has won their last six meetings, and he will be desperate to go on and win the 'Sunshine Double' after his triumph at Indian Wells.
We will preview both semi-finals in more detail in the next few hours.
