Soderling 4-4 Davydenko
Problems for Davydenko, who is suddenly the player being forced to scamper across his baseline as Rob-Sod attacks. A wild forehand flies a mile long and leaves him 15-40 down but he hits a clean winner into the corner with his next shot from that flank and, when a swinging serve takes him to deuce, he celebrates with a little fist pump that was practically invisible to the naked eye. It gets better for the Russian, though, who wins a ding-dong rally at the net with a smart volley and holds out when Soderling fires wide with a backhand. End result: We’re still on serve.
** Denotes NEXT serverSoderling 4-3 Davydenko
What’s this A first unforced error on serve by Rob-Sod - a forehand that flies out. Another follows on the next point to take Davydenko to 0-30 and a sniff of a first break. Soderling’s forehand reminds me of King Kong trying to swat a bi-plane from the top of the Empire State building, but it isn’t half effective when he connects - which he does to bring us back to 30-all. Chance gone No. Soderling’s next forehand only finds the net and we have our first break-point, which the Swede saves by following up a thumping serve by flashing a winner into the opposite corner. Two more huge deliveries see him hold out too.

Davydenko is trying to keep Soderling on the move but the Swede seems able to reach balls by stretching alone sometimes - he’s definitely not the fastest around the court. Still, Davydenko does enough to hold again and we’re still with serve in the first set.

2115: David Felgate on BBC Radio 5 live Sports Extra: “Some players have fast serves but the thing about Soderling is that he has a heavy serve - even if you get a racquet on it, it’s difficult to get back.”
Soderling 3-2 Davydenko
More good news for Davydenko: he’s won a point on the Soderling serve. That’s one point in three games.
** Denotes NEXT server****Soderling 2-2 Davydenko*
Davydenko needs a decent service game here… and that’s exactly what he gets. Another hold to love, sealed with an ace.
** Denotes NEXT serverSoderling 2-1 Davydenko
Rob-Sod is completely dominant on serve at the moment - keeping Davydenko on the backfoot constantly. He holds to love again.
** Denotes NEXT serverSoderling 1-1 Davydenko**
Soderling has a big forehand too, but we haven’t seen much of that yet. He still gets to 30-all here, mainly because Davydenko is still finding his feet or, more accurately, finding the tramlines. The Russian produces a flurry of stunning shots on the next point but Rob-Sod is equal to them all, before putting a backhand in the tramlines. He repeats the trick seconds later to level us up at one-game apiece.
** Denotes NEXT serverSoderling 1-0 Davydenko
Soderling starts as he will hope to go on… with an ace. If you don’t know much about the Swede, then we might as well begin with his serve - um, it’s big. He holds to love.

2055: Are you ready Good. Robin Soderling will serve first and we are about to get under way.From BBC Sport’s Piers Newbery Tweeting from the O2 Arena:](http://twitter.com/piersnewbery)“Had been a bit concerned about atmosphere at this one but crowd up for it, clapping along to London Calling. May have lost its punk edge.”
From benny007 on 606:](http://www.bbc.co.uk/dna/606/A60086711)“If Soderling beats Davy then he by far surpasses my expectations of him, a truly fantastic player this year and deserves all the success he gets. Roger and Rafa take note - this is a man in the zone!”
2053: The players are on court knocking up now, and the crowd still seems very excited. Let’s hope this match keeps them that way. Oh, and if you’re confused about how the result will affect qualification from Group B please take a look at 2023 and 2026.
2050: By the way, I’d like it very much if you lot keep me company tonight… so please, get involved** on Twitter,](http://twitter.com/chrisbevan_bbc)text me via 81111, or join the chat on606.**](http://www.bbc.co.uk/dna/606/A60086711)Only if you really want to, though.
2047: Quite a reception for Robin Soderling from the crowd at the O2 Arena… and Davydenko gets the same when he follows him on court. The Russian looks non-plussed.2046: Nikolay Davydenko follows him for a brief pre-match interview and he definitely knows what he needs to do tonight: "If I win, I play semis. If I lose, it’s my last match this year."2044: Here comes Robin Soderling now - he’s already through, remember, so should Djokovic be worried No. “I always try to win every match I play,” says Soderling. "I will fight to the end of course."2042: Rafael Nadal vows to return stronger in 2010 after his defeat by Djokovic left him without a win, or set, from his three Group B round-robin games: "This tournament gave me the opportunity to see what I have to do to play better and to start the next year better. The goal is try to play hard and arrive generally in perfect condition."2040: Novak Djokovic talks about his fitness following his 7-6 (7-5) 6-3 win over Rafael Nadal: "I’m not saying I’m dead tired, I’m saying I’m exhausted from the season. And I think you don’t need confirmation from my face to see that. I think it’s obvious on the court that I’m not moving and I’m not that energetic as I was maybe in Paris or Basel."From BBC Sport’s Piers Newbery Tweeting from the O2 Arena:](http://twitter.com/piersnewbery)"Rafa may have lost all three matches but still the press conference star. How are you feeling (Smiling) “Finish battery. I need to make charge.”
2032: You might have caughtsome of Djokovic’s win over an out-of-sorts Nadal earlier today.Um, it wasn’t a classic was it I was still impressed by Nadal, however, despite his terrible form - the effort he put in despite having already been eliminated from the tournament bodes well for 2010.
From BBC Sport’s Piers Newbery Tweeting from the O2 Arena:](http://twitter.com/piersnewbery)“It’s fair to say the media centre isn’t exactly crackling with excitement like last night but I’m backing Super Rob and Niko to star tonight.”
2030: Phew. That’s the maths over and done with (thankfully), so let’s talk tennis. Rob-Sod v Nik-Dav will be difficult to call… assuming Soderling wants to win, of course. They’ve met nine times before in the past five years, with Soderling wining six of those encounters - including in Paris earlier this month. Most of the recent form belongs to him too…in six matches with the Russian since 2006, he has only lost once.
2026: In terms of who could finish top of Group B, and play Juan Martin del Potro rather than Roger Federer tomorrow, then things are slightly more complicated but, luckily, not much:
Any Soderling win obviously means he finishes top. A two-set Davydenko win will be enough for him, but a three-set Davydenko win will still leave Soderling on top.
2023: Yep, the last match of what has been an intriguing (and, at times, brain-scrambling) round-robin stage will see Soderling play Davydenko. The shakedown is thus:
A Soderling win sees him go through, along with Djokovic. A Davydenko win will see him progress out of Group B, along with Soderling. Basically, if Davydenko wins, thensets won and lost by the top three players will decide who goes through.Soderling is untouchable with a W4 L0 (+4) record because the worst he can finish with is +2. Djokovic has finished his matches at W4 L3 (+1) so Davydenko, who is currently W3 L2 (+1) only needs a victory of any sort to better that.
2020 GMT: Evening folks. We already know three of the four semi-finalists of the ATP World Tour Finals… tonight we will find out whether Nikolay Davydenko or Novak Djokovic will join Roger Federer, Juan Martin del Potro and Robin Soderling in the last four. And the best thing You won’t need a calculator to work this one out…
