16:00 CET - Welcome back to our live coverage of the Miami Open, on a day where we will find out the women's finalists, as well as the last couple of men's semi-finalists.
Play gets underway at 18:00 CET, as world number two and tournament favourite Jannik Sinner looks to continue his phenomenal form at Masters 1000 level when he takes on home favourite Frances Tiafoe.
Sinner has won 28 sets in a row at Masters events, breaking Novak Djokovic's 10-year record. Tiafoe now stands in his way as he looks to complete the Sunshine Double (winning both Indian Wells and Miami).
The other men's semi-final sees the only other top-10 seed left in the competition, Alexander Zverev, meet Francisco Cerundolo.
If Zverev gets past Cerundolo, he will face Sinner in a rematch of their Indian Wells semi around two weeks ago, which Sinner won in thumping fashion. However, Cerundolo has been excellent in Miami, beating the in-form Daniil Medvedev to get here.
The head-to-head is locked at 3-3 between the pair, but Zverev has won their last three meetings after initially struggling against the Argentine.
The first women's semi-final sees fourth seed Coco Gauff clash with Karolina Muchova, as both players look to reach the Miami final for the first time.
Gauff has an extremely dominant record against Muchova, winning all five of their previous meetings - in pretty comfortable fashion, too.
However, Muchova is a player in fabulous form, and won her first 1000 event earlier this year in Doha. She will go into this contest with confidence, especially considering Gauff isn't playing that well at the moment.
The main event of the day comes in the second semi-final, as defending champion and world number one Aryna Sabalenka clashes with Elena Rybakina in what is currently women's tennis' best rivalry.
Sabalenka leads the head-to-head 9-7 and won their last meeting in an absolutely thrilling Indian Wells final. However, Rybakina won the two previous clashes, triumphing in the finals of the WTA Finals and Australian Open.
It is a wonderful rivalry between two players who hit the ball so hard but in slightly different fashion. Sabalenka exerts maximum effort and applies topspin, while Rybakina hits the ball so flat with such ice-cool effortlessness.
Let us hope for another cracker!
