STOSUR 6-3 5-4 ZAKOPALOVA - Massive! What a massive hold for Stosur, who has fought back from 1-4 in this set to lead. That must've knocked the stuffing out of Zakopalova. Does she have it in her to hold serve?

BREAK - STOSUR 6-3 4-4 ZAKOPALOVA - She does it. She's back on level terms, and we're back on serve. It's a nightmare of a game for Zakopalova, who sends down a double fault, misses a couple of makeable forehands and sends a smash into the net.

STOSUR 6-3 3-4 ZAKOPALOVA - A monster hold for Stosur, who needed that to stay alive in this set. Both women have a number of chances to win the game, but the Aussie finds that little bit extra to grind out a couple of important points and secure the hold. If she can just break now...

BREAK - STOSUR 6-3 2-4 ZAKOPALOVA - We have the set's fourth consecutive break of serve, and it comes in a hugely fortunate manner. Stosur does well to fashion a break point, but is on the defensive when Zakopalova is servnig at 30-40. The Czech has Stosur on the run and comes into the net off a decent approach shot. The game should be level at deuce, but Stosur's backhand clips the tape and evades Zakopalova's racquet.

BREAK - STOSUR 6-3 1-4 ZAKOPALOVA - Disappointment for Stosur who fights back from 0-40 to bring it back to deuce, but the Australin can do very little as she is out-hit, out-manoeuvred and out-thought. She'll want to break now or faces the prospect of a deciding set.

BREAK - STOSUR 6-3 1-3 ZAKOPALOVA - Stosur breaks back straight away. A real high quality game of tennis sees the two trading blows from the baseline.

BREAK - STOSUR 6-3 0-3 ZAKOPALOVA - This set is running away from Stosur at a rate of knots. The Aussies in the stands have gone very quiet, with Zakopalova making the most noise in the stadium as she hits winner after winner. There's been a real momentum swing.

SET - STOSUR 6-3 ZAKOPALOVA - Zakopalova sensed she had a real chance to break back in that last game and, with it slipping out of her hands, so, too, did her intensity.

STOSUR 5-3 ZAKOPALOVA - Stosur consolidates the break, but she does her very best to throw the game away. The Aussie misses a swinging volley at the net at 40-0 and then somehow lets Sakopalova bring it back to deuce. Two more game points come and go before a wicked inside-out forehand flies past the running Czech.

BREAK - STOSUR 4-3 ZAKOPALOVA - It's now Zakopalova's turn to have a mini meltdown and look towards her camp for help. A real error-strewn game, which includes a double fault and three unforced errors, hands Stosur an instantaneous break back.

BREAK - STOSUR 3-3 ZAKOPALOVA - A real wayward game from the Aussie sees the Czech level the set at 3-3. Zakopalova is up 0-40 in a flash, but Stosur digs deep and grabs two points back in quick succession, but the Czech doesn't allow her opponent any more. It's back on serve.

STOSUR 2-1 ZAKOPALOVA - The Czech is on the board. She serves well to get to 40-0 but then a double fault and a wayward backhand gives Stosur a sniff of another break. Zakopalova ensures her first game with a pinpoint serve out wide.

STOSUR 2-0 ZAKOPALOVA - It's a real high-tempo start from the home-favourite, who is penetrating the court with powerful ground strokes. Zakopalova can't keep up with her at the minute. The home crowd are in full voice.
