6-6 - We head for the tiebreak. Sela threw down his fourth ace of the match. A very comfortable hold. Roddick has had little joy on the Israeli's serve.
4-6 - Feliciano Lopez has booked his place in the last eight with a 6-2 6-4 win over Julien Benneteau. A possible match with his fellow Spaniard Rafael Nadal looms large in the quarter-finals.
5-6 - Roddick had to stave off a break point in that game. Had to rely on his big first serve to bail himself out of trouble there. Games continue on serve.
5-5 - Roddick managed to win two points in that game, but Sela refuses to budge. His agility and movement have been highly impressive here today. No breaks in this set.
- Frenchman Richard Gasquet has withdrawn from his third-round match due to a knee injury. The 11th seed had been due to face Rainer Schuettler for a place in the quarter-finals. The German will now meet Roddick or Sela in the last eight.
4-5 - Superb response by Roddick. Just when he needed it, he comes up with a love game on serve. Some wonderful serving and volleying. The wind isn't helping either player here. Sela serves to stay in the second set.
4-4 - Another all too easy game for Sela. Roddick failing to make any impression on the Sela serve. Worrying times for the American.
3-4 - Roddick moves ahead by the odd game game in seven in this second set. Roddick has thrown down nine aces.
3-3 - Former England cricket captain Michael Vaughan is watching this one. Sela is playing like a first-class Test player. Stroking the ball all around the court almost at will. He holds to love.
2-3 - Roddick holds serve in that game. Looking a lot more comfortable on his serve in this second set, but he has a bit more work to do if he is to win this match. Yet to break Sela.
2-2 - Sela levels us up at 2-2 in the second set. Difficult to call this one. Some of the punters are returning to their seats after lunch. Hopefully, they have some more decent fare to tuck into.
1-2 - Roddick being forced to play a few extra shots in every rally. Sela has been as high as 29 in the world. No reason why he can't get back to that level on this showing. Games continue on serve.

1-1 - Everything is working at the moment for Sela. Really impressive play. The backhand is so deceptive and his reflexes are also finely tuned. Roddick tests him in that game, but Sela comes throught it. Games on serve.
0-1 - Roddick forced to save one break point, but Sela brings up another which Roddick saves with the help of a timely big first serve. Poor shot into the net by Sela gives Roddick advantage. That was a long game, a tough game but Roddick gets out it. He lets out a huge roar. Little wonder.
6-4 - More erratic play by Roddick and Sela has two set points! He throws down a big first serve to secure the set. Could be an upset on the cards!
5-4 - The sun is shining on Centre Court at Queen's. Roddick has recovered slightly, but he must break in this game. Can Sela see it out?
5-3 - Sela moves to within one game of the opening set. His serve is deceptively fiendish. Roddick will serve in the set.
4-3 - Sela continues to look remarkably assured on serve. He and Roddick are managing to get 67% of their first serves in. One suspects Roddick will have to maintain a high standard to break the world's 67th best player.
4-2 - Better returning game for Roddick, but Sela provides enough ammunition to keep the American at bay. He remains a break up here.
3-2 - Roddick responds with a big service game. He drops only one point on that service game and is starting to look as if he is getting things together. Roddick has taken only four points of the Sela serve so far.
3-1 - A love game from Sela! Sensational lob to win that game. Magnificent play by the Israeli! He cements his break of serve.
2-1 - Roddick looking a bit tentative on serve. Sela strings together an array of impressive groundstrokes. He claims the first break of the match. Plenty of variety on display by Sela.
1-1 - The game quickly goes to deuce. Mistakes from Sela give Roddick a break point, but he is unable to convert them. Games continue on serve.
0-1 - Sela is only 5'9. Not the biggest man. He plays a couple of glorious passing shots trailing 0-40, but Roddick sees out the first game of the set.
0-0 - Roddick to serve in this opening game of the day.
0-0 - Roddick has won the one previous encounter between the players at the China Open in 2008. The American enjoyed a 6-4 6-7 6-3 success.
12.45 - Players finally on court. A threat of rain and a bit overcast, but they are out there.
12.21 - A bit cloudy today, but hopefully the rain will stay away.
12.10 - Good afternoon and welcome to today's coverage from the AEGON Championships at Queen's Club. We have Andy Roddick, Rafael Nadal, Andy Murray and Novak Djokovic for you today. Should be another interesting day with only Roger Federer missing from, some may argue, the world's top five players on grass.
