A first semifinal for both of them in Miami!

Both players are reaching their very first semifinal in Florida here, but by very different paths. Karolína arrives brimming with confidence after taming the power of Victoria Mboko without dropping serve in the match, even saving a set point with impressive composure at the net. On her side, Coco had to fight physically and mentally to push Belinda Bencic aside. The exact reason for the Swiss player’s drop in level after the second set is linked to a flu-like condition, as Belinda was reported to be under the weather before the match, which explains why she seemed to collapse physically at the end. Coco is not at 100% either, as her team had initially urged her to withdraw because of a nerve issue in her right arm, but she’s compensating with heroic resilience.

If we compare her 2026 season stats with those specific to this Miami tournament, we see a Karolína Muchová running extremely hot on serve. She’s gone from 77.2% of service games won over the season to an incredible 91.1% this week in Miami. Her dominance ratio jumps to 2.545 compared to just 1.386 for Coco, which shows that she’s cruising through her matches while the American is constantly walking a tightrope. The big black mark for Coco here is her serve, which has turned into a real nightmare with 0.58 double faults per game. The charts confirm that Karolína is much cleaner on pressure points, winning 75.4% of those points on her serve in Miami compared to 60.7% for Coco.

The head-to-head record is unequivocal with 5 wins to 0 for Coco, but the trend could flip tomorrow. The forecast is calling for a stifling 80% humidity and swirling winds blowing at 22 km/h. While humidity generally favors Coco’s endurance, the wind is likely to disrupt her already unstable ball toss even more. Karolína, with her velvet touch and sliced variations, has the perfect tools to exploit these windy conditions and break the American’s rhythm. We’re heading toward a battle where the Czech’s technical cleanliness will clash with Coco’s ironclad defense in an atmosphere that will inevitably be hostile for the visitor.
