NEW YORK (Reuters) - Garbine Muguruza cantered into the U.S. Open fourth round with a 6-1 6-1 demolition of Slovakian Magdalena Rybarikova on Friday to set up an exciting clash with Petra Kvitova.

The Spanish third seed, who claimed her second grand slam at Wimbledon this year, barely broke sweat on Louis Armstrong Stadium against the 31st seed.

Muguruza, one of the pre-tournament favourites, dropped serve once, the only glitch in a neat display.
