FERRER 4-6 6-3 6-1 - GAME, SET & MATCH! An underwhelmed looking Ferrer jogs up to the net after a Tipsarevic forehand goes astray. There's no real celebration from the Spaniard, with nothing riding on the match, and instead he just looks tired. But he departs London with two wins out of three and will head to Prague for the Davis Cup final against the Czech Republic next weekend
FERRER 4-6 6-3 5-1 - Tisarevic denies Ferrer on his first game point, pushing the Spaniard deep before popping up to the net to dink an easy forehand volley into the open court. But there is nothing Tipsarevic can do about it second time around and Ferrer holds to leave Tipso serving to stay in this match
FERRER 4-6 6-3 4-1 - BREAK! Tipsarevic really is looking like he's in his final match of the season now as he tamly concedes his serve once again. Ferrer, still not going through to tomorrow's semi-finals even if/when he does win this match, will have the Davis Cup final next weekend before he gets to the end of season break
FERRER 4-6 6-3 3-1 - A love hold for Ferrer as he consolidates the break early in this third set. It's just the one break but it does open up a considerable window for the Spaniard
FERRER 4-6 6-3 2-1 - BREAK! Tipsarevic is furious with himself and flings his racquet to the ground in disgust after a fairly regulation forehand ends up in the bottom of the net. It clearly works, albeit it only briefly, as the next point is sublime from the Serb but another forehand error and Ferrer has break points. But only one is needed as Tipsarevic's forehand catches the top of the tape and sits up a little for the Spaniard who races up to the net and whips it away for a forehand winner
FERRER 4-6 6-3 1-1 - Tipsarevic seems to have his legs back as he charges around the baseline to get Ferrer on the back foot only for someone in the crowd to yell out just before he hit what should have been a straightforward winner to break. Tipso ends up hitting the ball out and Ferrer goes on to survive and hold
FERRER 4-6 6-3 0-1 - No trainer for Tipsarevic during the change of ends but he opens the final set with an easy service hold and a unreturnable on the final point. He'll be pretty pleased if he can keep all his service games ticking over like that
FERRER 4-6 6-3 - SET! Ferrer levels the match with a fairly cruisey service hold, sealing it in the end with an unreturnable serve
FERRER 4-6 5-3 - Tipsarevic looks bizarrely out of break and is taking an age between points but he does manage to hold and at the very least force Ferrer to serve out this set. It would not be surprising if we see the doctor and/or the trainer for the Serb at the end of this set
FERRER 4-6 5-2 - Only a double fault at 40-0 up ruins what would otherwise be a perfect game for Ferrer as he holds to consolidate that break lead and leaves Tipsarevic preparing to serve to stay in this second set
FERRER 4-6 4-2 - BREAK! Apparently neither player actually quite knows how to win this match as Tipsarevic labours through a service game that he eventually concedes with an error to hand Ferrer the initiative back in this second set. Also the longer this match goes on the more it favours Ferrer, you get the feeling Tipsarevic really needs to get it won in straight sets if he's going to win at all
FERRER 4-6 3-2 - BREAK! Just when he was beginning to look like he had exorcised all the demons he was struggling with early in the match, Ferrer looks irritated again and hands Tipsarevic the break back with a forehand out of play. And he swipes at the court with his racquet in frustration on the way back to the chair
FERRER 4-6 3-1 - Tipsarevic does a much better job on serve this time around as he gives Tipsarevic nothing and instead races through to get his side of the scoreboard ticking over again
FERRER 4-6 3-0 - Ferrer races through another service hold to consolidate the break and he is firmly back in this match now and looking increasingly in control
FERRER 4-6 2-0 - BREAK! Tipsarevic handing the initiative to Ferrer with a double fault that hands the Spaniard three break points. Tipsarevic saves the first with a great dipping backhand that Ferrer can only return into the net. But the Spaniard does break at the second attempt when Tipso sends an off-backhand wide
FERRER 4-6 1-0 - A great lob from Ferrer that a rapidly retreating Tipsarevic can only clip with the frame of his racquet and thats a hold to open the set for the Spaniard
FERRER 4-6 - SET! Another set point goes begging for Tipsarevic when he is made to run by Ferrer, only ending when he sends an off-balance cross court forehand wide. But the Serb sets up a third chance and this time he gets it, a cracking off-forehand winner across court to secure Tipsarevic's first set of the week
FERRER 4-5 - Ferrer inches every closer to levelling up this match as he holds once again without too much trouble, when Tipsarevic sends a backhand wide. The Serb will have one last chance to serve out the set next ...
FERRER 3-5 - BREAK! With just over half an hour gone and Ferrer is facing a set point after dumping a cross court forehand into the net ... But the chance goes begging for Tipso as he stops mid-point to challenge on a vicious forehand down the line only to be proven wrong. He gets a second chance but again the Ferrer forehand saves it. And the Spaniard then goes on to break when Tipsarevic sends a cross court forehand wide
FERRER 2-5 - BREAK! A backhand long from Ferrer hands Tipsarevic another two brea points. The Spaniard has won just one point behind his second serve so far this evening. He saves the first break point by working his way up to the net and dinking a forehand volley winner into the open court. But there is little he can do about the second as he slaps a forehand long and Tipso will serve for the set after the change of ends
FERRER 2-4 - BREAK! An ace from Tipso gets him out of trouble at 15-30 down but a great return from Ferrer sees the Serb back in trouble and staring at a break point. A break point that the Spaniard takes full advantage of, Tipsarevic just missing a cross court backhand just wide. Tipso still has the one more break lead though
FERRER 1-4 - Much better from Ferrer as he gets a game on the scoreboard, running round the ball on the opening point and firing an off-forehand winner right onto the line before going to to hold with an ace
FERRER 0-4 - Tipsarvic races through another service hold without any troubles. He already has 16 points to his name, while Ferrer has just six. The Spaniard is looking totally out of sorts tonight
FERRER 0-3 - BREAK! Tipsarevic opens the game with a blistering forehand return of serve right at the feet of Ferrer, who has barely finished his service motion. And the Serb does break for a second time just a few points later when Ferrer sends a wayward forehand well wide
FERRER 0-2 - Three points into the game and Ferrer has already hit six uncharacteristic unforced errors, and he smashes his racquet on the ground, cracking it but playing the next point before changing it so as not to concede a penalty point But an ace from Tipsarevic on the next point sees him hold and consolidate the early break
FERRER 0-1 - BREAK! Not a great opening from the Spaniard as he ends up hitting long to hand Tipsarevic the early break. It must be frustrating for Ferrer knowing when he got up this morning that this match still counted, but that now (with Del Potro having beaten Federer this afternoon) it now has no affect whatsoever
Here we go then, David Ferrer wil open the match by serving first and we are ready to get underway ...
Who do you think will win this match, and which of the players left in the tournament would you like to see come out on top in London?
The line-up for the semi-finals will not be known until after the evening match between David Ferrer and Janko Tipsarevic. Victory for Tipsarevic would see Del Potro top the group while a win for Ferrer would mean three players are tied on two wins and in that case Federer would win Group B because of his superior sets percentage and Del Potro would be runner-up.
Federer, who had won 12 consecutive matches at the tournament since a semi-final defeat by Nikolay Davydenko in 2009, also finished group play 2-1 and had already qualified for the semis before walking on court.
Del Potro, fresh from beating the Swiss in the Basel final a fortnight ago, claimed a 7-6 4-6 6-3 victory at the O2 Arena to guarantee himself one of the top two places in Group B with a 2-1 record, the same as defending champion Federer.
Earlier this afternoon, Juan Martin del Potro beat Roger Federer 7-6 4-6 6-3 to reach the semi-finals of the ATP World Tour Finals.
