Phew. What a great day watching rugby. Can't wait for tomorrow. #hk7s— Hong Kong Sevens (@Hong Kong Sevens) 22/03/2013 13:42
So all teams have completed one match in the pool phase.
Argentina and Wales top Pool A, ahead of Australia and South Africa.
In Pool B, New Zealand and Kenya both won, defeating France and USA respectively.
In Pool C, Samoa looked mighty impressive in disposing of England. Portugal lie second in the pool after their dramatic last-gasp win against Scotland
And in Pool D, Fiji and Canada are in first and second place, both looking in top form against Hong Kong and Spain respectively.
Argentina defeat South Africa 21-0 in the last game on day one. Juan Ignacio Brex scores a try in the dying seconds to round off an impressive display by the Pumas over the Las Vegas champions.
Nicolas Bruzzone has enough speed to touch down a grubber kick before it crosses the dead-ball line and ARgentina are now 14-0 up on South Africa with 1one minute remaining.
The Pumas' Nicolas Bruzzone comes on as a sub and immediately makes an impact. He receives a quick tap penalty to burst over from short range.
With the conversion, Argentina lead South Africa 7-0 with four mins remaining.
That's what you call an attritional half of sevens. 0-0 between South Africa and Argentina. Defence on top, but you guessed that already.
New Zealand head coach Gordon Tietjens: "France played pretty well, they came out firing just after half time and scored a couple of good tries. Every one lifts their game here, and they were very tough to beat. We look at DJ Forbes, Lote Raikabula and Tim Mikkelson, and we will need that experience here."
Gillies Kaka rounds off an impressive second half performance from NZ with a try to seal a 33-12 victory over France.

NZ's Tim Mickelson runs half the width of the pitch, dummying as he goes, then spots a gap and cuts through to score a great try. New Zealand lead France 21-12.
And on the stroke of half time, Lote Raikabula scores his 90th try of his Sevens career to give the current Series leaders a 14-5 lead at the break.
But Ben Lam scores under the posts to give the lead to New Zealand 7-5.

Paul Albaladejo gets France straight back into this match after half time, picking up from the base of a ruck near the NZ line and scampering round to score.
The conversion makes it NZ 14-12 France with five mins to go.
Sam Edgerley scores nothing more thana consolation try as Samoa complete a 28-7 victory. New Zealand take on France next.
..and Tulolo Tulolo snaffles a gap when Samoa gain posession in the England 22 to make it 28-0 with one minute to go.
No score so far in the second half. England with more possession, but Samoa's physical advantage is seeing them push England back towards their own goal line. 21-0 to Samoa.
England coach Ben Ryan speaks to his players at half time: "Don't panic. Just get ourselves back bit by bit. They will be worried when we get the ball so take your time."
Faatoina Autagavaia runs a great line and races clear to extend Samoa's lead over England to 21-0 at half time.
Samoa completely on top so far and lead 14-0. England haven't yet been in the Samoa half. One min to go till half time.
Canada's strength and precision prove too much for Spain in the second half. Nathan Hirayama, Sean Duke and Taylor Paris alls core after the break as Canada win 31-7.
Next up, Samoa v England!

Canada and Spain very evenly matched so far, but Canada lead 12-7 at half time thanks to tries from Taylor Paris and Ciaran Hearn.
In between, Pedro Martin pounces on a loose ball to score for Spain.
@IRBSevens Well done to Liverpool Ref Ian Tempest on his International 7s debut taking charge of Fiji v Hong Kong. Not a bad way to start.— RugbyRefs (@RugbyRefs) 22/03/2013 12:08
It's a sellout on a Friday night! And the crowd are all waiting for the climax to day one with four mouth watering matches to come.
First up, Canada face Spain. Next it's a real heavyweight clash as Samoa take on England. Then NZ take on France before the last match on day one sees South Africa play Argentina.
Bring it on!

Canada lead Australia 19-0 at half time in the women's final.
Now there's a break in the men's tournament as Canada face Australia in the final of the HK women's sevens tournament.
..and Tonga hold on despite some late Tunisia pressure to win it 14-12.
Tonga turn things around with two quick tries at the start of the second half to lead Tunisia 14-12.
Tunisia show impressive handling skills and ability to retain possession as they lead Tonga 12-0 at half time.
Tunisia score two tries early on - the first a real pearl after some intricate passing - to take an early 12-0 lead over Tonga.
Enorme essai de la #Tunisie face aux #Tonga !! Contre attaque de 90m, très très beau !! #HK7s— Jérémie Dufour (@Jérémie Dufour) 22/03/2013 11:20

Next up @brasilrugby Sevens make their debut at #HK7s against Japan.— Sevens World Series (@Sevens World Series) 22/03/2013 10:55
Next week's tournament hosts, Japan, face Brazil next.
Russia score eight tries in a comprehensive 43-5 win over Cook Islands.
Russia's Alexander Yanyuskin runs a great curved line around and through the Cook Island defence before timing a beautiful pass out to the left wing, where Vladislav Lazarenko is in the clear to touch down. Class from Yanyuskin.
HK coach Dai Rees on Hong Kong's opening match against Fiji: "Welcome to the core teams! Fiji did it, seven mistakes, seven tries. We were overawed, and we have to grow up now overnight. We lick our wounds and we will be a different team tomorrow."
Russia's Igor Galinovskiy scores four first-half tries as his side take a 26-0 lead into half time against Cook Islands
Well David, Russia has a landmass of approximately 16,376,870 square km, whilst Cook Islands is 240 square km, so around 68237 times!
Watching Russia playing the Cook Islands at the Hong Kong Sevens. I wonder how many times the Cook Islands would fit into Russia?— David Flewellen (@David Flewellen) 22/03/2013 10:37
RT @JonThom82: Great win Wales. Outstanding defence in the last few minutes. #HK7s— Welsh Rugby Union (@Welsh Rugby Union) 22/03/2013 10:35

Next up, RWC Sevens hosts Russia take on Cook Islands.
..and there is still time for Australia's Shannon Walker to break clear, but his grubber kick bounces agonisingly over the dead ball line and Wales win 19-14. What a match!
But Wales hit back! They get the ball, spread it from side to side until Cory Allen skipe a tackle and races in to score. With the conversion Wales lead 19-14.
Australia's Lewis Holland scores two converted tries early in the second half to turn the game around against Wales and lead 14-12. Australia seem to be in control now, with Wales struggling for possession.
RT @DanCarter: Good luck to the All Blacks Sevens in Hong Kong this weekend #HK7s.— SherryReynolds (@SherryReynolds) 22/03/2013 10:23
Wales sevens coach Paul John talks to his team at half time against Australia: "You've got to work hard to get to that breakdown. Keep possession, keep possession, keep possession!"
Wales lead 12-0 at half time against Australia. They soaked up the Aussie pressure and hit them with two classy tries.
Great tackle by Wales' diminutive winger Lee Williams on the sizeable Aussie Pama Fou. He goes low and hard as Fou tries to use his bulk and speed to barge over in the corner.
And moments later Williams streaks down the field to score the opening try of the match.
Mike Friday, Kenya coach: "It is not about rebuilding confidence after USA, we have it, but sometimes it isn't there. You say that was the easy one in our pool, but we have a very physical group and so it is good to go into day two with a win."
Australia lead the head to head with Wales in HSBC Sevens matches with 22 wins to Wales' four.
Kenya defeat USA by 17-14 in a second successive match that goes down to the wire. Next up Wales play Australia.
Coach Alex Magleby during the USA half time team talk: "On the restart, if we're going to tap, it's got to be far back."
Seesaw between USA and Kenya as the hooter goes for half time. Kenya lead 12-7, but this one is wide open.
Portugal's Duarte Moreira on scoring four tries against Scotland: "I just had the luck to have the ball. I took a chance and the luck went with me."
And Portugal's Duarte Moreira scores his fourth try in the corner to break Scottish hearts! Pedro Leal adds the conversion from out wide to make it 27-20 at full time.
Portugal back on the attack with 13 secs to go
Mark Robertson and Andrew Turnbull produce two pieces of magic and with two Colin Gregor conversions, Scotland are suddently 21-20 ahead against Portugal. One minute to go.
Four tries for Portugal against Scotland in the first half - three from kicks. Scotland's Andrew Turnbull scored his 125th HSBC Sevens try in reply so Portugal lead 20-7 at the break.
South stand update, we are nearly at capacity! #HK7s http://t.co/uaJgI0v0sV— Sevens World Series (@Sevens World Series) 22/03/2013 09:36
Two clever kicks and two tries to Portugal early on against Scotland. They lead 10-0 three minutes in.
Scotland play Portugal next. They have played 26 times. 16 wins for the Scots and 10 for Portugal. Who will come out on top this time?
Fiji defeat Hong Kong 36-0 to set down an impressive early marker to the rest of the teams in this tournament.
The Sevens commentators just said that Fiji and Kenya have the best supporters..no matter where u go in the world.. #ProudlyKenyan :-D— Martin Mutiga (@Martin Mutiga) 22/03/2013 09:22
Hong Kong on top for the first couple of minutes of the second half, but Fijji spread the ball in their own goal line and, with a jink and 100m run from Benito Masilevu, they extednd their lead to 31-0. Pure class.
Fiji down to six, but they still lead Hong Kong 24-0 as half time approaches. Very impressive from a much-changed Fiji team.
@stephenjones9 Sevens great to see some fantastic offloads and rugby played in spaces.— Tom (@Tom) 22/03/2013 09:10
Uruguay defeat Chinese Taipei 24-12 and now we move onto the main HSBC Sevens competition with hosts Hong Kong facing Fiji.
So do we Sam. We love all nine rounds on the HSBC Sevens World Series!
A huge roar greets Fiji and Hong Kong. Here we go!
Uruguay lead 14-7 at the break after dominating for much of the first half. But Chinese Taipei scored late on and will now fancy their chances of getting back into this match.
Let's have your tweets #HK7s ahead of the first match in the HSBC Sevens competition at 17:06 local time. WHo is going to win this tournament? Are you in the stadium? Get in touch!
Tyronie Howe, Jamaica captain: "We had a slow start as usual. We have speed and agility which we didn't use in the first half. Hopefully we can start right on top tomorrow. Second half, we started better, we tend to crack under pressure, which is what happened in the first half."
Uruguay play Chinese Taipei for the very first time next.
Georgia win it 27-17, but that doesn't begin to tell the story of the second half.
Jamaica were down to five men at one stage, with two in the bin, but still managed to score three good tries, after Georgia had extended their lead. The Jamaica comeback coincided with moving the ball wider, but it was too little too late.
80 mins to Kenya Sevens! Thank God It's Mike Friday!— Wachira Dedan (@Wachira Dedan ) 22/03/2013 08:29
HT and Georgia lead 15-0 over Jamaica. Jamaica are being overrun at the breakdown so are going to have to find a way to manouevre the Georgians around in the second half.
Thanks for all the good luck wishes tonight. En route to ground for a 'Blow Out' and into our routine. Signing off till post match. #HK7s— Ben Ryan - England7s (@Ben Ryan - England7s) 22/03/2013 08:20
Next up we have Georgia v Jamaica, also in the pre-qualifier tournament.
Bruce Hobson, Zimbabwe team manager: "We have been working hard since early January. We have high expectations and we raised the level in Harare a few weeks ago and we must be pleased with that win."
Zimbabwe score three more second half tries to win it 27-0 over Mexico. Mexico had a few chances late on, but kicked when they were well placed.
Zimbabwe's Tafadzwa Chitokwindo scores one and sets up another as Zimbabwe take a 15-0 half time lead over Mexico.
Zimbabwe's nous proving too much for Mexico at the moment as they lead 5-0 early on.
Zimbabwe and Tunisia run on to the pitch. We are moments away from the start of the party!
Less than five minutes to go now till Zimbabwe v Mexico.
Referees warming their bodies up too for the #HK7s which starts in 9 mins! http://t.co/KOlKotKOLA— Sevens World Series (@Sevens World Series) 22/03/2013 07:51
