Hello and welcome to LIVE comments from this fourth round clash between fourth seed Andy Murray and Serbian 15th seed Viktor Troicki.

MURRAY 4-6 4-6 2-2 - BREAK - Murray earns himself two break back points. But only the one is needed as he gets up to a drop shot from Troicki and dinks it back over the net for a drop shot winner of his own. We're back on serve in this third set

MURRAY 4-6 4-6 1-2 - BREAK - Troicki earns himself a break point and takes full advantage with a great forehand return of serve that has Murray on the back foot and the Scot's flailing backhand reply drifts harmlessly long to gift the Serb the game

MURRAY 4-6 4-6 1-1 - The first love service game of the match goes the way of Troicki as he levels up very quickly and slings all the pressure back on to Murray over the other side of the net

MURRAY 4-6 4-6 1-0 - Murray holds for the opening game of the second set but his petulant behaviour continues as he keeps up an almost continous monoligue

MURRAY 4-6 4-6 - Murray was very lucky not to lose that second set on a code violation as he smashesd his second racquet in the match, this time on his foot. The umpire had already given him a warning and would be well within his rights to deduct a point this time but he didn't.

MURRAY 4-6 4-6 - SET - Troicki drops the first point of the game with a forehand into the net but he recovers in time to earn himself two set points with a great first serve that Murray cannot return. He saves the first with an angry, slapped forehand return winner across court and Troicki squanders the second with a double. But he gets a third chance when Murray hits wide and this time he finds a first serve that Murray cannot return. Troicki leads by two sets to love

MURRAY 4-6 4-5 - BREAK - Murray gets himself out of a potential spot of bother at 15-30 down with an ace right into the corner of the service box. But a double fault on the next point hands Troicki a break point. Murray saves it with some brutal hitting that eventually forced Troicki into a defensive backhand, that drops wide, but the Serb gets a second chance. And this time he gets it, taking advantage of another poor drop shot from Murray and sealing it with a smash winner.

MURRAY 4-6 4-4 - A drop shot from Murray hands him two chances to re-establish his break lead. He slices a backhand into the net to concede the first and puts up an easy forehand volley for Troicki on the second, the Serb finding the winner. And Troicki goes on to hold with a forehand winner as Murray tells his camp about a "terrible miss"

MURRAY 4-6 4-3 - BREAK - Murray sends an absolutely wild forehand well long of the baseline after being pushed well wide and it gifts Troicki the break back point. Murray saves it with a series of huge blows that eventually force the Serb to hit wide. A forehand into the net hands Troicki a second chance to break back and this time the Serb does get back on level terms, Murray slicing a drop shot into the net

MURRAY 4-6 4-2 - BREAK - Murray earns himself a first break point in this set with a running forehand passing shot winner off a smash from Troicki. The Seb saves it with a high forehand volley winner down the line but Murray earns himself a second chance and this time Murray does break with a cross court forehand winner

MURRAY 4-6 3-2 - Decent serving in the end from Murray but he had a real struggle to hold as Troicki pushed him all the way to deuce before hitting long and handing the game to the Scot

MURRAY 4-6 2-2 - Troicki pulls the trigger on a forehand down the line, only to hit into the net. But it doesn't hold him up for too long as Murray slams a forehand return of serve into the net on the next point to help the Serb to hold

MURRAY 4-6 2-1 - Murray is forced to save break points but does so with two great first serves both of which Troicki returns long of the baseline. An ace goes on to bring up a game point for the Scot and he goes on to hold with an angled forehand that Troicki returns into the net

MURRAY 4-6 1-1 - Super play by Troicki as he gets up to a decent drop shot by Murray and feeds the backhand down the line for a winner. And the Serb goes on to hold and level up when Murray hits into the net

MURRAY 4-6 1-0 - Murray holds for the opening game of the second set, but only to 30, when Troicki hits a forehand forehand into the bottom of the net

MURRAY 4-6 - SET - Murray gets up to consecutive drop shots to put pressure on the Troicki serve at 30-30 before the Serb tries something different and works his way into the net to fire off a forehand volley winner. But another drop shot from Troicki (the smartest move?!) ends up with another point to Murray and it earns him another break point. Murray hits long to waste the chance, while Troicki saves a second with a drop shot and the Serb goes on to hold for the set when Murray hits long

MURRAY 4-5 - Four games in a row now for Murray as he holds to 15 with a huge serve out wide that Troicki can only return into the bottom of the net. The Scot is beginning to move a little better now as he works his way back into the match, although Troicki still has one break left and has one more chance to serve out this first set

MURRAY 3-5 - BREAK - Murray grabs the second break back, whipping a forehand passing shot across court for a winner. He's still not moving very well, Murray, but he is beginning to find his range as he belts absolutely everything in reach

MURRAY 2-5 - Two aces from Murray see him hold for the first time and put a second game of the board. But Troicki will have a second chance to serve out the set after the change of ends

MURRAY 1-5 - BREAK - Murray earns himself a break point when Troicki falls foul of a net cord and slaps long after the Scot's cross court backhand had caught the top of the tape. Troicki levels with a great first serve but he hits long again to hand Murray a second chance and this time the Scot does break to get off the mark, Troicki hitting a forehand into the net

MURRAY 0-5 - BREAK - A blistering cross court forehand from Murray gets him off the mark at 0-30 down but he hits a high forehand into the net to concede more break points. The first is saved by Murray after a great first serve but Troicki comes up with a fantastic forehand passing shot onto the sideline on the second and the Serb will serve for the first set after this change of ends
