Muchova’s Miami Open Semifinal: Can She Break the Gauff Streak?
The Miami Open has reached the final four, setting the stage for compelling matchups. In Thursday’s semifinals, all eyes will be on American Coco Gauff as she faces Czechia’s Karolina Muchova for the sixth time on the WTA Tour Driven by Mercedes-Benz, starting at 3:00 p.m. (7:00 p.m. GMT). Later, World No. 1 Aryna Sabalenka and No. 2 Elena Rybakina will continue their burgeoning rivalry, with the night session kicking off at 8:30 p.m. (12:30 a.m. GMT).
Notably, excluding the WTA Finals, Sabalenka and Rybakina are the first top two players in the PIF WTA Rankings to clash before a final since Martina Hingis and Jana Novotna at the 1998 US Open semifinals. Let’s dive into what you need to know about these exciting semifinal contests.
Gauff vs. Muchova: A History of Dominance
Head-to-Head: Gauff leads 5-0
Last Meeting: Gauff d. Muchova 6-1, 3-6, 6-3 at the 2026 Australian Open Round of 16
Coco Gauff has consistently found a way to win, even when challenged. Her incredible defense, showcased against Belinda Bencic in the quarterfinals, often turns into winning points. Gauff has also been remarkably clutch in deciding sets. Her serve has been a major weapon throughout the tournament, and her movement will be severely tested against Muchova, who prefers to develop rallies on her forehand.
“I definitely think that, every time I play her, it’s a tough match, and I expect the high level that she’s going to bring, like she does every match,” Gauff stated. “Honestly, I know we kind of know what we’re going to do to each other, and it’s just about who can execute it better.”
On the Line: A win would send Gauff to her sixth career WTA 1000 final, making her the third youngest player to achieve this since the format’s introduction in 2009 (following Caroline Wozniacki and Iga Swiatek).
Muchova’s Momentum: A Different Player in 2026
While Muchova hasn’t historically defeated Gauff, she’s playing the best tennis of her career. Her title win in Doha and subsequent victory over Victoria Mboko (a Doha final rematch) in the Miami quarterfinals demonstrate her current form. This is already her third semifinal of the season, surpassing her total from last year.
Against Mboko, Muchova landed an impressive 70% of her first serves and wasn’t broken, facing only two break points. If she can maintain that level of serving and prevent Gauff – who has broken opponents 22 times this tournament – from capitalizing, she’ll have a strong chance of securing her first win over the American.
“I feel like everyone is playing incredible,” Muchova said. “I don’t have the best record against Coco, but I feel good. It’s going to be a really tough battle. Even the record, I mean, I would always take the challenge to play and to try to break it.”
On the Line: Muchova could reach her eighth career tour-level final and secure her second hard-court final of the year.
Sabalenka vs. Rybakina: A Rivalry Defined
Head-to-Head: Sabalenka leads 9-7
Last Meeting: Sabalenka def. Rybakina 3-6, 6-3, 7-6 (6)
This matchup is quickly becoming the biggest rivalry in women’s tennis. Sabalenka won the most recent encounter just under two weeks ago to claim her first Indian Wells title and 23rd career singles title. This will be only the second time they’ve met in the semifinals.
Sabalenka’s power is a defining characteristic, often matching Rybakina’s intensity. She fired 29 winners against Rybakina in the Indian Wells final and won 67% of her first service points. She’s also aiming to complete the Sunshine Double and defend her Miami title.
“I enjoy our rivalry, I enjoy our battles,” Sabalenka said. “I feel we both push each other to the limits and I feel this kind of matches make me as a better player, and this is where I actually grow.”
On the Line: Sabalenka could reach her 44th career singles final on the WTA Tour and her fourth of 2026.
Rybakina’s Resilience and Pursuit of a Title
Rybakina demonstrated her resilience in her quarterfinal against Jessica Pegula, finding a way to win even when not at her best. Her 15 aces were the most in a single match this tournament. She frequently came to the net against Pegula, a tactic that could prove effective against Sabalenka.
Rybakina is on the verge of reaching 100 main draw wins at a WTA 1000 event, currently at 99 after her victory over Pegula. She’s a two-time finalist in Miami (2023 and 2024) but is yet to lift the trophy.
“I’m just on – let’s say – path of this consistency for now, this year has been good,” Rybakina said. “But I feel like the season is not even halfway yet, and it’s great to play against Aryna. Always pushing each other and you can see what you need to improve. If she wins, it’s going to be another challenge, where I will need to serve well and really take care of my game, knowing that on the other side, she can hit a lot of good shots, also winners, good serve.”
On the Line: Elena Rybakina could reach her third Miami Open final, becoming the player with the most appearances in the final since the tournament moved to Miami Gardens in 2019.
