Great early showing from Jankovic, who makes Sharapova work for it and earns two break points. However, the defending champion hit two massive forehands on the way to rescuing deuce. The two trades blows in the deuce, with Jankovic possessing an advantage on four occasions, only for Sharapova to respond. However, she secured the first game after encouraging Sharapova to slam the ball out of play.

Sharapova is certainly going after her opponent and is absolutely smashing the ball back at her.

Jankovic may be sporting some strapping on her left shoulder, but she certainly isn't taking it easy against her "arch-nemesis".

25 minutes gone, and Sharapova is serving to stay in this opening set.

BREAK, GAME AND SET! Wow, what an opening set. Sharapova falls straight to a 30-0 deficit with both shots creeping just out. A touch less power on her efforts, and she may even be winning this contest. She comes back though with a nice stride towards the net after an obvious drop shot from Jankovic but then hammers a shot into the net to give Jankovic two set points. The leader is pegged back as she fails to deal with the spin on the champion's shot but takes the set as Sharapova puts another strike the wrong side of the line.

Sharapova, who was yet to drop a set in this competition before today, has just lost her first without winning a single game.

BREAK! And it's a first game for Sharapova, who gets the crowd on her side with a wonderful lob to make it 15-15 before conceding the lead once more with another shot out of bounds.

BREAK! The power that Sharapova can get on her forehand when trying to break a serve is scary. She takes a 30-0 lead but loses out on an enthralling rally by putting her backhand out. After Jankovic levelled it up, she spooned an effort into the net, before Sharapova wrapped up her fourth game of the set.

This is almost a complete role reversal of the first set. Sharapova is taking it to her opponent now. She isn't going down without a fight that's for sure.

Sharapova has hit 22 unforced errors to just six from Jankovic though. Crazy.

These efforts are just steaming off the racket from Sharapova. Jankovic is looking increasingly disgusted.

What a back and forth battle in that game. Neither player wants to leave an inch as the score goes from 15-0, to 15-15, to 30-15 and so on, which inevitably leads us to deuce.

Jankovic then went back in front though in a cracking rally, as she curves a forehand outwards to the tramlines before correctly calling a Sharapova shot out to pile the nerves on the Russian. 5-4.

Outstanding from Jankovic as she takes two fantastic final points to edge out Sharapova from serve in the first set.

Now Jankovic turns it on, and swiftly moves to a 30-0 advantage. She keeps on her game and sends a flailing Sharapova all over the court. She takes the game for love and leads the set.

This could be some finish the way things are going...

She then hammers an unbelievable return to take it to deuce in search of a break. However, Jankovic takes the game after the Russian slams the ball into the net. 3-2 to the serve.

Jankovic isn't half partial to doing the splits. Tremendous viewing.

Back to square one once more. Jankovic was trying to put Sharapova on her forehand for some odd reason and paid the price. Sharapova takes the game with a wonderful winner down the line. 3-3

Sharapova is now two games away from the semi-finals and serving for her fifth game of the set.
