It promises to be an exciting fourth day of WTA Miami action. Madison Keys, Qinwen Zheng, and Sloane Stephens are among the players featured in this article. All the other matches, including Coco Gauff vs Elisabetta Cocciaretto, Aryna Sabalenka vs Ann Li, Elena Rybakina vs Yulia Putintseva, Jessica Pegula vs Francesca Jones, Naomi Osaka vs Talia Gibson, and Amanda Anisimova vs Ajla Tomljanovic, are covered in our other pieces.

WTA Miami Day 4 Predictions
Anna Kalinskaya vs Anastasia Zakharova

Head-to-head: First meeting

Zakharova recovered from losing the first set against Anna Bondar in the previous round. She was the aggressor throughout that battle because of her opponent’s gritty style. Kalinskaya will be much more attacking than the Hungarian. Zakharova always produces at least a few brilliant shots, but I doubt her defense is capable of holding up against Kalinskaya on her favorite surface.
Prediction: Kalinskaya in 2

Qinwen Zheng vs Sloane Stephens

Head-to-head: Zheng 1-0 Stephens

Although Jennifer Brady is in the early stages of her comeback after a severe injury, Stephens still performed impressively to comfortably win their match and set up this meeting. Zheng’s level has been inconsistent since returning from her own injury this season. Nonetheless, I expect the Olympic Gold Medalist to triumph here. Stephens’ typically passive approach is unlikely to work against an opponent who does not mind biding her time and waiting for the correct moment to strike.
Prediction: Zheng in 2

Leylah Fernandez vs Oksana Selekhmeteva

Head-to-head: First meeting

Fernandez has endured a rough start to 2026, having won only two matches. Selekhmeteva generated attention by reaching the Australian Open third round, and she beat Emiliana Arango to confirm this matchup. Despite her lackluster form, I think Fernandez will win this battle of the left-handers. Selekhmeteva’s backhand is vulnerable against pace, and the Canadian is adept at taking the ball early on that side.
Prediction: Fernandez in 3

Madison Keys vs Elena-Gabriela Ruse

Head-to-head: Keys 2-0 Ruse

The head-to-head does not encapsulate how challenging Keys has found this matchup. She won 7-6 2-6 7-5 in the second round of her 2025 Australian Open run before another 6-7 7-5 7-5 triumph at Wimbledon a few months later. The medium-speed hard courts in Miami should suit the American more. Keys is backed in straight-sets for that reason, but do not be surprised if Ruse causes her trouble again.
Prediction: Keys in 2
