Svitolina ends Marta Kostyuk's strong run to advance to 4th round

MELBOURNE, Australia (AP) Elina Svitolina has ended 15-year-old Marta Kostyuk's strong run at Melbourne Park.

The fourth-seeded Svitolina beat her fellow Ukrainian 6-2, 6-2 on Rod Laver Arena to advance to the fourth round.

Kostyuk, who had nine double faults Friday, including on match point, received entry into qualifying because of her junior girls' victory last year at the Australian Open. She won all three qualifying matches, then her first two in the main draw.

Her win over Peng Shuai in the first round made her the youngest player to win a main-draw match at the Australian Open since Martina Hingis in 1996.

Kostyuk entered the tournament ranked No. 521. A Women's Tennis Association official said Friday her ranking should improve to around 250 because of her performance at Melbourne Park.
