Defending champion Iga Swiatek endured wind, pressure, and a spirited challenge from Diana Shnaider to claim her spot in yet another clay-court quarterfinal. After a major power outage halted Monday’s matches at the Madrid Open, the world No. 2 kicked off Tuesday’s rescheduled play by grinding out a hard-fought 6-0 6-7(3) 6-4 win over 13th seed Diana Shnaider in a tense 2-hour and 34-minute clash — continuing her remarkable run on her favorite surface.

This victory marks Swiatek’s 17th straight quarterfinal appearance on clay, a streak that began after her 2021 third-round loss to Ashleigh Barty in Madrid.
