SCOTLAND were denied a Singapore Sevens quarter-final place after ripping up the form book to defeat Argentina yesterday.
But the Argentines then turned their fortunes around to beat South Africa and edge Scotland out on points difference.
The Scots, beaten 33-14 by opening Pool C opponents South Africa, bounced back to stun Argentina 19-14 with Andy Turnbull and Mark Lee playing starring roles. A 40-7 victory over Hong Kong then strengthened Scottish claims for a last-eight place, but it wasn't to be.
Scotland's hopes were dashed after Argentina beat South Africa 19-17 in their closing pool game, and
Argentina and South Africa both progressed to tomorrow's final stages.

England, four-times Hong Kong Sevens champions and Commonwealth Games silver medallists in Melbourne last month, were due to face Samoa in their final group match late last night.

On the domestic front, there was a huge turn-up in the quarter-finals of the BT Shield when Perthshire, champions of National League Division 1 and due to play premiership rugby next season, were comprehensively beaten 47-6 by Falkirk, the champions of National League Division 3.
It was all Falkirk as they built up a 33-6 half-time lead. The first two tries fell to former Scotland international Kevin McKenzie.
Scrum half Matt George also bagged a touchdown, as did Alan Wells, Chris Harris and Mark McKenzie - who succeeded with six conversions. All Perthshire had to offer were two penalties from Geraint O'Driscoll.
Falkirk now go north for their semi-final which will be against Ellon, who edged out RHC in a great tie by 21-20.
Ellon had the better of things in the first half with tries from Alex Cadzow and Michael Cox plus a conversion and two penalties by Mark Ryan.
However RHC, who had scored a penalty by Iain Welsh, added a try to end the half with left winger Duncan Sherman scorching over.
Continuing to fight back from the half-time deficit of 18-8, RHC proceeded to take a 20-18 lead with two good tries from Matt Hines and Ross Thomson, with Welsh converting the second.
However, with 30 seconds to go, Ryan lined up a pressure penalty and struck it home to send the men from the north through.
