Swiatek storms into Madrid Open quarter-finals by crushing Sorribes Tormo

Iga Swiatek continued her march towards back-to-back Madrid Open finals by crushing home favourite Sara Sorribes Tormo in straight sets in the last 16 on Monday.

The world number one – who lost to Aryna Sabalenka in last year's final – made a poor start as Sorribes Tormo surprisingly broke her serve in the opening game, but that only spurred her into action as she dominated from there.

Swiatek broke back immediately and reeled off 12 straight games to advance 6-1 6-0, going one better than her 6-1 6-1 win over Sorana Cirstea in the last 32.

On clay, Swiatek has now won nine of her 55 WTA 1000-level sets by 6-0, with that remarkable rate of 16.4 per cent being the highest of any player to have played 10 or more sets in the format's history (completed matches only).

Swiatek will face Beatriz Haddad Maia in the last eight on Tuesday, with the Brazilian upsetting Maria Sakkari 6-4 6-4 to reach her first quarter-final at the event.

Data Debrief: Swiatek unstoppable on clay?

Since the turn of the century, only two players have a higher rate of quarter-finals reached on clay – Martina Hingis (85.7 per cent, 12/14) and Justine Henin (80.6 per cent, 25/31).
