Jelena Ostapenko prevails over 11th seed Caroline Wozniacki

Ostapenko's next opponent is 30th-seeded Timea Bacsinszky of Switzerland, who eliminated 13th-seeded Kristina Mladenovic of France 6-4, 6-4. She can play aggressive. She left the arena in a similar state. She didn't panic when the experienced Dane took the first set after coping with the blustery conditions much better than Ostapenko, whose flat groundstrokes have little margin for error.

"We had all the seasons rolled into one today", Bacsinszky said. I saw her in the gym just right after our matches today, and we both said mutually to each other, 'Well done.' We hugged each other, because she's a really nice girl.

Latvia's teenage firecracker Jelena Ostapenko recovered from a terrible start to blaze past former world No 1 Caroline Wozniacki into the French Open semi-finals on Tuesday.

The 19-year-old is the youngest player to advance to the women's Semifinals in Paris since Ivanovic in 2007. The expected sonic wave of support had not yet materialised, although at each change of ends more and more spectators flooded in, sated by their sacred French lunches. "There was fine weather, then rain, wind and a sandstorm".

The conditions were far from flawless.

After the second restart of the match, Bacsinszky sealed her place in the semifinals for the second time in three years with a 6-4 victory in the second set.

It was all the more impressive considering she hardly slept the night before.

But so too are there hints of the same brittle fragility that occasionally hijacked Pierce's game.

It also halted proceedings with Bacsinszky leading Mladenovic by a set.

Sometimes, nerves get the better of Timea Bacsinszky. Ostapenko's power game has been on fire and after battling back from a set down in the fourth round, she is going to have all the momentum rolling. She broke on the third time of asking in the seventh game and after saving a pair of set points on her own serve, broke when the former world #1 netted a backhand to pull back the entire deficit. Players wiped their eyes when dust kicked up from the clay court.

In 2014, she was ranked outside the top 100 and went through qualifying at the French Open.

When they returned, Mladenovic raced into a 3-2 lead.

Bacsinszky, who will be at least No. 22 by next week, will face Jelena Ostapenko next.

"Both of us will have the birthday, so I'm really looking forward to the match", said the soon-to-be 20-year old (Bacsinszky will turn 28 on Thursday).

Tuesday's match was one hour 49 minutes in duration but took the best part of six hours to complete after two rain delays - one lasting three hours.

Wozniacki of Denmark won the first set but couldn't match Ostapenko's style of play over the final two sets.

- Spaniard Nadal was scheduled to face his compatriot Pablo Carreno Busta, while defending champion Djokovic was due to play Austrian Dominic Thiem.
