Hello and welcome to LIVE coverage from the second of the women's quarter-finals on day nine of the Australian Open. This one is between Serbia's 14th seed Ana Ivanovic and 30th seed Eugenie Bouchard of Canada.

GAME, SET AND MATCH - IVANOVIC 7-5 5-7 2-6 BOUCHARD - An absolutely fantastic final point from Bouchard. No signs of nerves at her situation whatsoever as she continued to play aggressive tennis right through that final point, stepping inside the baseline and thumping a forehand winner away to seal her place in a maiden Grand Slam semi-final.

IVANOVIC 7-5 5-7 2-5 40-Ad BOUCHARD - Ivanovic looking very nervy as she gives away the first two points of the game on errors. The Serb pegs one point back with a great forehand volley deep towards the baseline and then levels at 30-all by following a superb serve up the court and producing a forehand winner across court. Bouchard goes long with a forehand. A sensational off-backhand winner across court, right to the corner, sees Bouchard level at deuce before Ivanovic goes long. Match point...

Ivanovic will have to serve to stay in this match after the change of ends...

IVANOVIC 7-5 5-7 2-5 BOUCHARD - Ivanovic has absolutely the whole court to aim at with her volley but appears to have too much choice as she dumps the backhand into the net and hand Bouchard two game points. The Serb denies her on the first but can do nothing about the second and Bouchard holds after a very calm point, working Ivanovic from one side of the court to the other before eventually over-stretching the Serb and finding a forehand volley winner.

IVANOVIC 7-5 5-7 2-4 BOUCHARD - Bouchard is really firing now as she thumps a low backhand passing shot winner down the line to level up at 30-all. Another fine return of a good Ivanovic serve brings up break point although it goes begging with a forehand long. Another break point is secured with the perfect forehand volley but again the Canadian cannot take advantage of it and instead Ivanovic goes on to hold with another cracking serve.

IVANOVIC 7-5 5-7 1-4 BOUCHARD - Ivanovic sneaks ahead with some fantastic touch on the backhand drop shot that Bouchard cannot get to before the double bounce. But the Canadian steadies the ship with a backhand winner across court before going on to hold at the first attempt to consolidate her break lead.

BREAK - IVANOVIC 7-5 5-7 1-3 BOUCHARD - The first Ivanovic outburst at her camp comes after Ivanovic lifts up on a backhand and sends the ball long of the baseline. It's two more break points to Bouchard and this time she does take advantage, Ivanovic netting a backhand after a deep, tricky return from the Canadian.

IVANOVIC 7-5 5-7 1-2 BOUCHARD - Bouchard races through a comfortable service hold, Ivanovic's one point coming after a lucky net cord. The 19-year-old is not showing any signs of nerves at this stage of the final set though and sneaks ahead once more with a bakchand winner and a big serve that Ivanovic cannot return in play.

IVANOVIC 7-5 5-7 1-1 BOUCHARD - The double faults are starting to flow from the Ivanovic racquet now as she hands Bouchard two early break points in this final set. The Serb saves them both with a couple of much better serves though before being frustrated by Bouchard saving a number of game points. Ivanovic produces her first ace to bring up another game point and this time she does hold when Bouchard fails to land a forehand.

This match is fascinating now. It's as big a deal for Ivanovic to get to her first Grand Slam semi-final since 2008 as it is for Bouchard to reach her first ever Grand Slam semi. And with the injury seemingly playing on Ivanovic's mind, can she maintain her focus?

IVANOVIC 7-5 5-7 0-1 BOUCHARD - Ivanovic fights back from triple game point to Bouchard to level at deuce. But the Canadian holds firm and fires down a big first serve that draws the mis-timed forehand from Ivanovic, before leaping all over the shorter return from the Serb and holding with a forehand winner down the line.

SET - IVANOVIC 7-5 5-7 BOUCHARD - Ouch. Ivanovic opens the game with a double fault before going on to hand Bouchard a set point with a netted forehand. A second double in the game puts an end to this second set in favour of Bouchard. We are going to a decider.

IVANOVIC 7-5 5-6 BOUCHARD - Bouchard also stops the run of broken service games against her. She opens with a forehand winner before drawing Ivanovic into the net and forcing the Serb into a backhand volley error. A double fault is the only down point for Bouchard in the game as she holds to leave Ivanovic serving to stay in this second set.

IVANOVIC 7-5 5-5 BOUCHARD - Ivanovic is beginning to look a little more comfortable again now after a couple of games since the injury timeout of struggling to get going again. And she races through a service hold for the loss of just the one point to properly level up once more.

BREAK - IVANOVIC 7-5 4-5 BOUCHARD - A thumping forehand return of serve winner across court from Ivanovic quickly followed by a double fault from Bouchard and Ivanovic has chances to break back once again. A poor lob attempt, easily dealt with by Bouchard, wastes the first but she does break back for a second straight time when the Canadian pulls a backhand wide across court. Was that nerves that got to Bouchard? Serving for a set in her first Grand Slam quarter-finals.

BREAK - IVANOVIC 7-5 3-5 BOUCHARD - Wow, did Bouchard mainain her concentration during the medical timeout. The Canadian belts a forehand drive volley winner and an inside-out forehand winner across court to no response whatsoever from Ivanovic to re-establish her break advantage.

Ivanovic has been playing with some strapping on her right upper thigh all tournament and has taken an injury timeout for treatment to that same area, or for the strapping to be re-done.

BREAK - IVANOVIC 7-5 3-4 BOUCHARD - A fouth game point goes begging for Bouchard when her forehand down the line drifts wide and instead Ivanovic earns herself another break point with a curling forehand winner across court, right into the corner. And this time Ivanovic does secure the break back when Bouchard sends a forehand just long. The Canadian challenges but she also heads back to the chair, suggesting a lack of confidence in the challenge. The ball was out.
