Jelena Ostapenko, 19 year old , became the first Latvian woman to reach a Grand Slam semi-final as she stunned Danish 11th seed Caroline Wozniacki 4-6, 6-2, 6-2. Before this, she had never been beyond the third round at a major. Now, she has gone step further than compatriot Anastasija Sevastova at last year’s US Open.
The 27-year-old Bacsinszky broke French hearts in the other quarter-final as she beat 13th seed Kristina Mladenovic 6-4 6-4.
The men’s quarter-finals featuring nine-time champion Rafael Nadal and defending champion Novak Djokovic were postponed until Wednesday after two rain delays disrupted Tuesday’s play.
Nadal is due to face fellow Spaniard Pablo Carreno Busta with Djokovic taking on Austrian Dominic Thiem.
