It's already becoming a battle for bronze.

Quan Hongchan has 174.80 after two dives, Chen Yuxi has 160.90.

Spendolini-Sirieix is in fifth, with 139.20.

And another one into the top eight at the skateboarding.

Mixed feelings for Brazil as Dora Varella edges ahead of team-mate Isadora Pacheco.

Her score of 82.29 is enough to boot out Pacheco's 82.07.

She was really pumped on the first dive, maybe she took a little bit too much off the second. The entry was okay, she was just a little low on the water. The score is fair, but it's hard work from here.

Ah, not the cleanest entry for Spendolini-Sirieix in her second dive. She executes the inward three-and-a-half somersaults but is slightly under-rotated as she enters the water.

That scores 62.40. She's in third, but the two Chinese divers are still to come.

Spain's Naia Laso has just catapulted herself into contention for the final with an excellent run of 82.49 in round two.

She's followed into the 80s by Finland's Heili Sirvio who burst into tears after scoring 83.42.

Neither is enough to overhaul Sky Brown but they have knocked reigning Olympic champion Sakura Yosozumi out of the final.

Elsewhere this morning, we saw more speed-climibing qualifiers.

No, it is not an episode of Gladiators, it is one of the most thrilling events in the Olympics.

Speed climbing is very simple, the fastest to reach the top of a 15m-high wall wins - and Sam Watson was very fast.

The American broke his own world record on his way to reaching the quarter-finals, shaving 0.04 seconds of his previous best to reach the summer in just 4.75 seconds.

Spiderman has nothing on this guy.

It really is a thing of beauty from Quan Hongchan. Utter perfection.

That's why the judges saved the 10s, that is outstanding from Quan Hongchan. There is nothing there. This is why she won the Olympics at 14 years old. Straight 10s.

My word, the entrance into the water from China's Chen Yuxi and Quan Hongchan is unreal!

They literally disappear, like the water has absorbed them.

And Quan, the defending champion in this event, scores straight 10s for a 90.00!

After the first round of five, Spendolini-Sirieix is in fourth place.

It's really good! Andrea Spendolini-Siriex is so pumped up, she's got electricity running through her veins, it's effected her entrance ever so slightly with a minor, minor rotation. If it wasn't for that, it would've been 9s and 9.5s. Her coach Alex knows that is wonderful though.

The bravery and the control is just unbelievable when the divers start with the backwards-facing handstand on the edge of the board. I can barely even watch with nerves.

But Andrea Spendolini-Sirieix nails it for her first dive, going into second place with 76.80.

Nice start.

In the semi-final Andrea Spendolini-Sirieix stepped-up her game and she was comfortable coming into the final - she feels like she has more to give.

I'm feeling good and confident, Andrea had a beautiful competition yesterday. It's the best diving she has done and I was impressed with her composure.

I believe in my daughter and I know she is ready - her vision is to dive the best she can do.

Her aim is to get gold.

Strong start from Italy's Sarah Jodoin di Maria, going for her most difficult dive first - perhaps playing a few mind games to get herself an early boost up the scoreboard.

After four dives, she leads with 72.000 with Mexico's Gabriela Agundez Garcia in second.

Rankings are decided by the combined points total of each competitor’s five dives during the final.

Seven judges score each dive out of 10 in half-point increments.

The two highest and two lowest judges’ scores for each dive are discarded.

The scores of the remaining three judges are added together and multiplied by the degree of difficulty for that dive.

Got it?

On Chinese divers, Chen Yuxi and Quan Hongchan...

They are incredible.

Without fail they will land on their heads and have no splash, it is about putting as much pressure on them as possible and Andrea Spendolini-Sirieix is doing that.

Fans are starting fill up the Aquatics Centre as anticipation ramps up for the main event.

At the moment, the Chinese and the Mexicans are having a contest who can make the loudest noise.

They're soon beaten by the DJ. Like a nightclub in here - especially when the lights are dimmed and House of Pain blasts out.

China and Mexico dominate the flag waving competition, too. Britain are probably third.

Andrea Spendolini-Sirieix is Britain's medal hope in the 10m platform diving final this afternoon. During the Games build-up, she tested GK Barry's nerve by speaking to her for BBC Sport... at the top of a diving board.
