The WTA Mutua Madrid Open moves into the Round of 16 with a lineup that blends rising talent, proven contenders, and intriguing contrasts in style. A teenager with growing confidence on clay looks to keep her momentum going, while other matchups pit consistency against shot-making and form against reputation. With a place in the quarterfinals at stake, expect tight moments, shifts in momentum and matches that could turn on just a few key points.

WTA Madrid Open Day 7 Predictions
Mirra Andreeva vs Anna Bondar

Head-to-Head: Bondar 1-0 Andreeva 

The one previous meeting between these two went Bondar’s way, and it came on clay. That said, the context here is quite different. Andreeva enters this match at 9-1 on clay in 2026, having already won the Linz title and reached the Stuttgart semifinals this spring. She has shown the ability to reset after early breaks, as demonstrated in her third-round win over Galfi, where she responded quickly each time the Hungarian threatened.

Bondar, for her part, has been one of the tournament’s surprise packages. She has not dropped a set in Madrid yet, and her second-round win over Svitolina showed real quality, she gave away no breaks and was dominant on serve. Bondar is 9-2 on clay in 2026 overall, so this is far from a mismatch. Still, Andreeva’s current clay-court level is a tier above what Bondar has faced so far this week, and the Russian’s baseline depth and acceleration in long rallies should prove the difference.
Prediction: Andreeva in 3

Ann Li vs Leylah Fernandez

Head-to-Head: Li 2-0 Fernandez 

Li holds a 2-0 advantage in the head-to-head, most recently winning their Doha meeting in February 6-4 6-3. Li reached the Round of 16 after benefiting from Swiatek’s retirement, but the route there wasn’t handed to her; she had moved ahead in the deciding set and showed the ability to recover after Swiatek leveled in the second.

Fernandez, meanwhile, showed strong mental resilience against Jovic, winning 12 consecutive points at a critical stage of the decider to pull away. Her left-handed serve creates problems and she is capable on clay, but her 2026 season overall has been inconsistent. Li has had the better of their meetings and plays a style well-suited to slowing down Fernandez’s rhythm from the baseline. The head-to-head record and the American’s return game edge give her the slight advantage here.
Prediction: Li in 3

Marta Kostyuk vs Caty McNally

Head-to-Head: Kostyuk 1-0 McNally 

Their only previous meeting went to Kostyuk, just a couple of weeks ago in the second round in Rouen the same tournament Kostyuk went on to win. The Ukrainian enters this match on an eight-match clay-court winning streak, having dismantled Jessica Pegula 6-1 6-4 in the previous round with 20 winners and a dominant return game.

McNally has done something genuinely impressive by reaching the Round of 16 at a WTA 1000 for the first time. She saved two match points against Siniakova to get here, and credits improved mental toughness through journaling and coaching work. That resilience is real, but Kostyuk right now is playing some of the best clay-court tennis of her career. She wins points in bursts, moves the ball efficiently, and reads pace well. McNally does not yet have the clay pedigree to consistently neutralize that. Kostyuk should get the job done, though the experience gap at this stage of a 1000 may not fully show in the scoreline.
Prediction: Kostyuk in 2

Aryna Sabalenka vs Naomi Osaka

Head-to-Head: Sabalenka 3–1 Osaka

Sabalenka won their most recent meeting comfortably 6-2 6-4 at Indian Wells in March. Sabalenka took that Indian Wells title and arrives in Madrid having won the Sunshine Double and currently sits at 25-1 for the season. Osaka, who cruised past Kalinina 6-1 6-3 has looked comfortable on this Madrid clay. She is a more-than-capable big-match player, and the level head-to-head record shows this is not a guaranteed one-way affair. However, Sabalenka’s weight of shot on clay, her second-serve aggression, and the momentum of a near-flawless season make her very difficult to stop over two sets. The Indian Wells result is the most recent and relevant reference point, and it was convincing.
Prediction: Sabalenka in 2​​​​​​​​​​​​​​​​
