Wozniacki reaches quarters after a seven-year wait
Caroline Wozniacki reached the French Open quarter-finals for the first time in seven years on Sunday with a 6-1, 4-6, 6-2 win over 2009 champion Svetlana Kuznetsova.
Danish 11th seed Wozniacki, who made her only other last-eight appearance in Paris in 2010, faces Jelena Ostapenko of Latvia for a semi-final place.
“Svetlana’s a great player, especially on clay so I knew it wouldn’t be easy,” said the 26-year-old after her eighth win in 14 meetings against the Russian.
Teenager Ostapenko reached her first Grand Slam quarter-final on Sunday with a 2-6, 6-2, 6-4 win over 2010 runner-up Samantha Stosur. Ostapenko, 19, who uses ballroom dancing as part of her training regime, hit 46 winners past the 23rd-seeded Australian, a semi-finalist last year.
