The Ukranian tennis player Kateryna Bondarenko has reached her first grand slam singles quarter-final, thrashing Argentina's Gisela Dulko 6-love, 6-love in the fourth round of the U.S. Open in New York.
Late arrivals on Arthur Ashe would have missed Bondarenko's 47-minute breeze against an error-strewn opponent who knocked out her seeded older sister Alona in round two.
She faces a last eight test against Petra Kvitova, conqueror of top seed Dinara Safina, or Yanina Wickmayer of Belgium.
