Monday at the Mutua Madrid Open, anticipated as a busy day, saw six Round of 16 matches suspended due to a widespread power outage affecting parts of Spain, Portugal, and southern France. Only two matches were completed before the halt: Coco Gauff defeated Belinda Bencic, and Mirra Andreeva overcame Yuliia Starodubtseva.
The remaining six matches were played and completed on Tuesday. Top seeds Aryna Sabalenka and Iga Swiatek were among the winners, successfully advancing to the quarterfinals. Tuesday delivered a full schedule of tennis, wrapping up a round that was delayed but not derailed by the unusual interruption.
