Next up on Chatrier, it’s the defending champion Iga Swiatek against Greece’s world number 18, Maria Sakkari. Number eight seed, Swiatek is the highest ranked player left in the women’s draw.

GAME, SET AND MATCH! - SWIATEK 4-6 4-6 SAKKARI. The champion is out! Sakkari makes it count as Iga returns wide on the third match point. It was a wonderful performance in a dominant one hour and 35 minutes from the No.17 seed. She will now meet Barbora Krejcikova in the last four. Wow, what a shock!

Sakkari serving for the match: After a lung-busting rally the Greek shows lovely composure to ease a drop volley over the net for 15-0…. Ace number 5 makes it 30-0... A wrong-footing forehand tees up triple match point... Iga saves one with a return winner...Another sharp return forces the error... Two MPs gone...

SWIATEK 4-6 4-5 SAKKARI. It’s a nearly game for Maria. She goes for her shots but misses a few by a whisker. She can’t quite things tricky for Swiatek and a drive volley finishes off a hold to 30. The defending champion is on the brink but poses the serve-out question to the Greek. Can she find that first serve for just one more game?

SWIATEK 4-6 3-5 SAKKARI. The first serve continues to tick along and keep Swiatek at bay. The Pole can’t make inroads from 0-15 and a fourth ace of the game sees Maria move within one of a major shock. That was a significant step but the biggest one is still ahead of her.

SWIATEK 4-6 3-4 SAKKARI. Maria comes out all guns blazing but the game turns at 0-15 when she reads a drop shot, charges in but blazes a sitter of a forehand wide. Iga jumps on the reprieve but then gets fortunate with a flick off the tape that ends with Sakkari dumping a forehand into the net when she looked all-set to force deuce.

SWIATEK 4-6 2-4 SAKKARI. You have to say that’s tremendous. Sakkari doesn’t allow the No.8 seed to get her teeth into the game as she rattles through a love hold to maintain her advantage.

SWIATEK 4-6 2-3 SAKKARI. Just when you think the shock is firmly on, Swiatek responds with clutch serving and hitting to bite back from double break points down to lay down the gauntlet. The 20-year-old Pole isn’t about to give up her title without a major fight.

SWIATEK 4-6 1-3 SAKKARI. The No.17 seed is as solid as a rock. Another beauty of a drop shot steals the show as she romps to a love hold. She can sense the opportunity is there for her and is determined to give it her best shot.

SWIATEK 4-6 1-2 SAKKARI. That delay hasn’t done Sakkari many favours. A couple of misses allow Swiatek to take charge in the game before she finishes it off with a rasping forehand down the line that appears to already have more pop and depth. Is the Pole about to hit the comeback trail?

Swiatek is back on court and has some heavy strapping on her right thigh.

Medical timeout: Swiatek goes off court for some treatment.

SWIATEK 4-6 0-2 SAKKARI. There’s no answer. Sakarri booms another forehand winner and finishes with an un-returnable wide serve to consolidate with aplomb. The Greek wants to maintain the charge but Swiatek calls for the trainer. Interesting. There didn’t appear to be an obvious problem but the medical team are now on court and stretching out the Pole's right leg.

BREAK! - SWIATEK 4-6 0-1 SAKKARI. Iga goes off court for a comfort break but when she returns the problems remain. A bizarre loopy rally sees her fire a slow-paced shot long before a wide forehand chokes up the instant break. Sakkari’s momentum builds.

SET! - SWIATEK 4-6 SAKKARI. What a show of grit and high-class hitting from Maria! She earns a set point with an ace but then has to fend off the break back opportunity when she sizzles a forehand just wide down the line. Some brave and intelligent serving earns her a second chance and she finishes off what is surely the rally of the opener with a rasping backhand winner. The Greek takes the set in 47 minutes and the reigning champion is in danger and has some work to do.

BREAK! - SWIATEK 4-5 SAKKARI. The favourite is in a little bit of trouble. She hooks a forehand wide to cough up another break after Sakkari had piled on the pressure to earn two bites of the cherry with more sharp returning. The 25-year-old will now serve for the set.

SWIATEK 4-4 SAKKARI. A real kicker of a serve towers above Swiatek and puts Sakkari in charge. The Greek No.17 seed wrong-foots her opponent with a third backhand winner of the contest before serving out another solid game to love. She’s not fazed by the occasion or the opponent here.

SWIATEK 4-3 SAKKARI. That’s a loose return game from Maria and Iga surges through an efficient love hold. The steady flow of errors at both ends of the court means this match has yet to really catch fire.
