Next up for Clijsters will be 12th seed Agnieszka Radwanska, who earlier battled past China's Peng Shuai but only after saving two match points.

E. Makarova

K. Clijsters

CLIJSTERS 7-6 6-2 - GAME, SET & MATCH - Makarova sends a backhand long after a series of huge ground-strokes from Clijsters and that earns the Belgian two match points. Just the one will do, though, as she belts a forehand across court that cannot returned into play by Makarova. Clijsters really had to work hard for that one but she is now through to her sixth Australian Open quarter-finals

E. Makarova

K. Clijsters

CLIJSTERS 7-6 5-2 - BREAK - Makarova saves a first break point with a very good first serve down the T that Clijsters can only return into the net. But the Russian can do nothing about the second and Clijsters breaks to leave herself serving for the match after the change of ends

E. Makarova

K. Clijsters

CLIJSTERS 7-6 4-2 - Makarova fires her backhand approach shot just marginally wide to let Clijsters off the hook at 30-15 and the Belgian quickly takes advantage with a backhand across court that Makarova can only return into the net. Clijsters is nudging nearer and nearer the quarter-finals now

E. Makarova

K. Clijsters

CLIJSTERS 7-6 3-2 - Despite throwing in a fourth double fault, Makarova holds to 30 to stay just the one break down in this second set, keeping the pressure on Clijsters not to let up

E. Makarova

K. Clijsters

CLIJSTERS 7-6 3-1 - Some absolutely huge hitting, from both women, ends when Clijsters whips a forehand winner across court, and right on the sideline, to earn herself a game point from deuce. And it's a game point she takes full advantage of straight away, again peppering the baseline until Makarova is pushed too far back and hits a low backhand into the bottom of the net

E. Makarova

K. Clijsters

Kim Clijsters had the trainer at the change of ends and took a couple of pills, asking how long they will take to take effect. About 15 minutes was the response although it was not entirely clear why Clijsters was taking them in the first place. She seems mainly ok though, nothing obviously wrong anyway

E. Makarova

K. Clijsters

CLIJSTERS 7-6 2-1 - BREAK - A few more errors are creeping into the Makarova game now as she misses a forehand wide down the line to hand Clijsters a break point. And a cross court forehand from the Russian catches the top of the tape on the very next point before bouncing well wide to hand the Belgian the break. Now we should see what Makarova is really made of - can she break back?

E. Makarova

K. Clijsters

CLIJSTERS 7-6 1-1 - Despite another couple of relatively poor misses, including a forehand into the net, Clijsters holds to level up. The Belgian did find a blistering cross court forehand, that Makarova could only return wide, and backhand down the line, that the Russian again hit long, for the last two points of the game but it's a bit hit and miss still from the world number three

E. Makarova

K. Clijsters

CLIJSTERS 7-6 0-1 - Clijsters drills consecutive backhands wide across court, the second a return of serve, as Makarova saves three break point before going on to hold when Clijsters sends a forehand into the net

Australian police are investigating an incident which led to a member of French player Aravane Rezai's family being banned from WTA events and which the tour described as a "serious safety matter".

E. Makarova

K. Clijsters

CLIJSTERS 7-6 - SET - Makarova hits a forehand into the net to hand Clijsters three more set points. And this time only one is needed as a battered backhand return across court and parried back long by Makarova. That was an incredibly tight first set and has taken 56 minutes but Clijsters has just snuck through it

E. Makarova

K. Clijsters

CLIJSTERS 6-6 (4-2) - TIE-BREAK - Clijsters comes up with a stunning forehand passing shot, whipped across court from two metres behind the baseline and way into the tramlines and their are gasps of awe from the crowd as Clijsters again does the splits to pick up a backhand before Makarova hits wide. But Makarova comes up with a series of huge ground-strokes to take the next point and trails only 4-2 at the change of ends

E. Makarova

K. Clijsters

CLIJSTERS 6-6 - TIE-BREAK - Two forehand errors and a double fault hand Clijsters two set points, after Makarova had opened the game with an ace. The first is saved after some ferocious hitting by the Russian, Clijsters eventually hitting into the net, while the second also goes begging this time with a solid first serve that the Belgian can only return long. And Makarova does go on to hold and force the breaker when Clijsters sends a forehand long of the baseline

E. Makarova

K. Clijsters

CLIJSTERS 6-5 - The world number three opens with a double fault, her second of the match, before holding without the loss of another point as she steps her hitting with a vicious forehand down the line

E. Makarova

K. Clijsters

CLIJSTERS 5-5 - Fantastic hitting from both women as these two, meeting each other for the first time, continue to feel each other out. And Makarova holds to 15 to keep this first set alive, a Clijsters forehand down the line drifting wide to end the game

E. Makarova

K. Clijsters

CLIJSTERS 5-4 - Makarova is really battering the ball now as she pushes Clijsters a good two metres behind the baseline. The Russian has a golden opportunity to earn herself a break point as well as she moves Clijsters around the baseline before missing the easy backhand down the line with plenty of space to aim at. And Clijsters goes on to hold when Makarova sends the ball long. The Russian will have to serve to stay in this first set after the change of ends

E. Makarova

K. Clijsters

CLIJSTERS 4-4 - Makarova starts the game with a double fault before an off-forehand winner across court from Clijsters helps her set up two more break points. The first goes begging when Clijsters sends a forehand return into the net and Makarova saves the second with a cracking forehand winner down the line after a good pick up. Clijsters earns herself a third chance but again Makarova saves it with a solid first serve. And Makarova goes on to hold when Clijsters hits long
