Monday`s highly anticipated action at the Mutua Madrid Open was unexpectedly interrupted by a widespread power outage affecting parts of Spain, Portugal, and southern France. This forced the suspension of six Round of 16 matches. Only two matches concluded before the outage: Coco Gauff defeated Belinda Bencic, and Mirra Andreeva overcame Yuliia Starodubtseva.
The six suspended matches were completed on Tuesday. Top seeds Aryna Sabalenka and Iga Swiatek were among those who advanced to the quarterfinals. The day successfully wrapped up the round, which, though delayed by the unusual interruption, was ultimately completed.
Round of 16 Results:
No. 4 Coco Gauff def. Belinda Bencic 6-4, 6-2
Gauff has now reached the quarterfinals at every current WTA 1000 event except her home tournament in Miami.
No. 7 Mirra Andreeva def. Yuliia Starodubtseva
With Monday`s victory, the Madrid Open became the first tournament where Andreeva has recorded 10 career wins at a single WTA event.
No. 2 Iga Swiatek def. No. 13 Diana Shnaider 6-0, 6-7 (3), 6-4
Swiatek has now reached 17 consecutive clay-court quarterfinals, a streak that dates back to her third-round loss to Ashleigh Barty at Madrid four years ago.
No. 5 Madison Keys def. No. 19 Donna Vekic 6-2, 6-3
Keys became the second American player to achieve 25-plus WTA-1000 match-wins on clay, along with Serena Williams (44).

Before this season, Svitolina had never won consecutive matches at the Madrid Open in nine previous appearances.
Moyuka Uchijima def. No. 21 Ekaterina Alexandrova 6-4, 7-6 (5)
Uchijima has made more WTA quarterfinal appearances in the past two weeks (Rouen and Madrid) than in her entire career before this run (Monastir in 2022).
No. 1 Aryna Sabalenka def. Peyton Stearns 6-2, 6-4
Sabalenka’s win on Tuesday was her 28th of the season, giving her the tour lead in match wins — one ahead of Jessica Pegula.

Kostyuk has already recorded 11 WTA 1000 wins in 2025 — her highest total in a single season at this level.
