1155: I'm sorry to hear about your storm GioCasRod. Good job my nimble fingers can access the 400m heat info....but it's more bad news I'm afraid. Nery Brenes missed out on 400m qualification by 0.19 seconds. Need anything else? Keep us posted on the weather situation....
1302: The 100 meters heats keep rolling on. Asafa Powell up next with GB teenager Adam Gemili.
1306: Fancy some more pix from the Olympic Stadium of the 100m boys?
1307: BREAKING NEWS: The (IOC) has today announced that it has excluded Russian athlete Victoria Baranova (cycling-track, women's sprint) and provisionally suspended Colombian athlete Diego Palomeque Echavarria (athletics, men's 400m). More details to follow..
1309: Usain Bolt is not the only Jamaican in the hunt for 100m gold. Yohan Blake in action very shortly....
1310: A lively women's pole vault competition taking place. Seven athletes have cleared 4.55m - one of those is American 30-year-old Jennifer Suhr.
1519: Serena now serving for gold at 5-1 in set two. She's chuffing on Centre Court like a steam train.
1521: The American flags are draped all around Centre Court. Not sure Russian president Putin is still in town but he won' t be delighted to see a rather off-colour Sharapova crushed by Serena. The crowd are jubilant as Serena performs a cheeky jig on the hallowed grass. I say "jig" - I'm sure it was something more majestic than that - open to suggestions. BUT WELL DONE SERENA. And a first Olympics singles tennis gold for the girl.
1524: The latest poll findings suggest that Super Saturday is your preferred choice. Other suggestions include: Slow Saturday (interesting) Serena Saturday (Massively spot on) Superfragilisticexpialidocious? (more interesting) AND Phelps farewell saturday (Was looking for suggestions beginning with S but I get your drift Kumar)
1527: It's half-time in the basketball and USA lead Lithuania 55-51.
1530: Trampolining used to scare me as a kid. What if my legs fall through those springs? That's what my head used to be thinking.....it was never going to be my Olympics event. It's the women's final just kicking off and American Savannah Vinsant has qualified in the big eight.
1536: Lithuania started brightly in the second half and got within one point - but Team USA have woken up and lead 63-58. Still tight though.
1540: Tennis FACT: Serena Williams and Steffi Graf are now the only tennis players to win the career “golden” slam – the Australian Open, the French Open, Wimbledon and the US Open – and now the Olympic Singles Gold. She's the first person, male or female, to win singles and doubles. Andre Agassi and Rafael Nadal have done the career “golden” slam on the men’s side, Roger Federer could do it tomorrow. He plays Andy Murray.
1616: On the subject of music and the Olympics and ringing eardrums - there seems to be a load of debate on whether music should be played during events. Good for the sport and spectators or should events be played without a soundtrack? What do you reckon? All thoughts in the comments form.
1624: So calling all Team USA basketball fans - have you been impressed with what you've seen so far? Just for the record, USA now go above France in Group A.
1626: From hoops to two wheels. Or rather six wheels. Team USA are up against the Australians in the women's team pursuit....And it's tight.
1627: Huge fist pumping in the velodrome as USA pip the Aussies on the line. That's the women's pursuit team in the final. Next up is GB v Canada.
1630: Serena's been chatting after her earlier victory over Sharapova. Who said that the Olympics doesn't mean anything to these players? Serena: "I didn't think I would be this happy. Oh my gosh, I got the gold. I have singles, doubles, actually everything there is to win in tennis. Where do I go from here?" Good question Serena...Where do you go from here?
1832: Back to my probing question from time 1816. It's Macca - yep Paul McCartney. And the crowd inside the Velodrome are buzzing, singing HEY JUDE. Crazy scenes. And if I was the MC - I'd be saying "Yeh great effort but there are 112 better Beatles songs you could be singing right now"...
1835: A great thought Fozzie-TX. Your words are conjuring up images of roller-discos from a couple of years back. Arhhh Happy memories. Disco on a bike - what do you reckon?
1838: Heptathlon's final event of the 800m is at 835pm. Two laps of the track. And here's what's needed by GB's Jessica Ennis. She holds a 188 point lead. If she runs a time of around 2:10 in the 800m, nearest challenger Austra Skujyte of Lithuania will need to clock close to 1:57 to win. Skujyte's PB of 2:15.92 was set in the Athens Olympics in 2004, while Ennis set hers of 2:07.81 last year. I don't want to jinx the British girl but it aint looking bad for her is it?
1842: PHELPS PHELPS PHELPS. I repeat - and I do repeat - his last ever race is at 8:46pm London time. There you go DaveS. Anything else?
1855: More on the women's 100m. It's the semis up first at 7:35pm. Look out for American Carmelita Jeter, Jamaicans Veronica Campbell-Brown, Kerron Stewart and Shelly-Ann Fraser-Pryce.
Callum Tennent for CNN:
1855 It’s all over in the match between Honduras and Brazil, and it’s the Brazilians who progress to the semi-finals. Those of you just joining us may not be surprised, but this has been a spectacular match absolutely packed with twists and turns. After taking a shock lead, Honduras then lost a man, conceded a penalty, took the lead again, then conceded twice in succession and had another man sent off (Roger Espinoza in the 90th minute). Sadly, such a bold effort will ultimately go unrewarded. Fingers will inevitably be pointed at the referee after some dubious decisions, to put it mildly. However, Neymar et al. won’t care one jot. All that’s left to see now is who will join them in the semifinals along with Japan and Mexico -- Great Britain and South Korea kick-off in 35 minutes.
1859: Athletics...track and field...whatever you call it, the Olympic Stadium is rocking....and it's the 400m hurdles semi-finals.
1902: Felix Sanchez of the Dominican Republic blasts away to stun the field and win the first 400m hurdles semi-final. GB's Dai Greene was a huge medal hope but was fourth and half a second off the pace. USA's Kerron Clement was third with a season best. It's the top two qualifying and two fastest losers go through. Joy for Sanchez - Greene says he's "devastated".
