Coco Gauff produced a stunning display to thrash four-time French Open champion Iga Swiatek 6-1 6-1 and reach the final of the Madrid Open.

Gauff, 21, had never beaten her Polish opponent on clay before but took just 64 minutes to dispatch the world number two.

American Gauff will play world number one Aryna Sabalenka or Elina Svitolina in the final.

Reigning champion Swiatek had won nine consecutive matches in Madrid – and 15 of 16 going back to her loss to Sabalenka in the 2023 final – but had no answer to Gauff.

Gauff, who won the US Open in 2023, hit seven aces and won 19 of 21 points on her first serve in a dominant performance.
