Fiji moved to the top of the HSBC Sevens World Series standings after a 24-17 victory over defending Glasgow Sevens champions New Zealand in an enthralling final at Scotstoun Stadium.
Apisai Domolailai scored twice in the victory, their fourth of the season, with the win moving Ben Ryan's side ahead of South Africa and New Zealand in the race for the 16th World Series title with one round remaining in London.
Ryan's side head into round nine in London on 147 points, with South Africa, who beat Scotland 12-10 in the Plate final, second on 142 and New Zealand on 139. England (117) came third after beating USA 24-19 to finish third and increased their lead over Australia (101) in the battle for the fourth and final Olympic qualification spot.
"This is the most amount of wins - four - that we've done in one season and we have put ourselves in a great position to win our first World Series in 10 years," said head coach Ben Ryan. "We have a fit team and we want to win back-to-backs now."
Isake Katonibau and two tries from Semi Kunatani were enough for Fiji earlier as they beat a spirited USA side, having earlier proved too strong for then leaders South Africa 15-0. Kunatani and Savenaca Rawaca scored tries in that win, a result which meant the Blitzboks failed to make a Cup semi-final for the first time all season. Rieko Ioane scored the only try in New Zealand's 5-0 win over England, the lowest scoring semi-final for 13 years in wet conditions in Glasgow.
Earlier Perry Baker was the star for the USA as he ran the entire length of the pitch to help Mike Friday's side come from 7-0 down and record a 14-7 win. The result meant New Zealand qualified for the Olympic Games in Rio, joining South Africa and Fiji who achieved the same on day one.
BLITZBOKS LIFT THE PLATE IN DRAMATIC FASHION
Werner Kok and Ruhan Nel scored tries for South Africa as Neil Powell's side won the Plate by beating Scotland 12-10 to collect 13 series points, having earlier dropped from first place in the overall series standings. Damian Hoyland gave Scotland, chasing their best-ever finish in a series, the chance to take the match to extra time sudden death with a try in the last play of the match before a missed conversion from Russell Weir who hit the post.
South Africa's captain Kyle Brown added after the match: "Playing Scotland in Scotland is one of the hardest thing you can do. I don't know what it is, perhaps it's the haggis."
Nel scored a hat-trick as South Africa beat Australia 21-12 to reach the Plate final while hosts Scotland had Joe Nayacavou to thank for his last-minute try against last year's runners-up Canada to book their place in the final.
WALES UNBEATEN ON DAY TWO
Luke Morgan scored two tries as Wales came from 7-0 behind to beat Argentina 12-7 and win the Bowl, winning all three of their matches on day two at Scotstoun Stadium.
Morgan, the Welsh hero, said: "It's been up and down but that's a great ending to go down to Twickenham with. It's all about consistency with us but everyone played well as a 12."
Earlier Franco Sabato, Santiago Alvarez and Ramiro Moyano scored second-half tries to give Argentina a safe passage through to the Bowl final despite Kenya's Collins Injera scoring his 199th career try in the 24-7 defeat. Kristian Phillips scored in Wales' 5-0 win over Samoa while Ramiro Moyano scored twice for Argentina in their quarter-final win over Russia before they beat France 12-5 to reach the final.
TOLOA DOUBLE GIVES SAMOA THE SHIELD
Samoa Toloa scored twice in Samoa's22-12 Shield final win over Portugal, having earlier added a double in their 24-14 win over Japan. Portugal earlier beat Russia 10-7 with Aderito Esteves also scoring two tries.
"It was disappointing for us here," said Portugal captain Pedro Leal. "We now need to make sure we maintain our status as a core side in London and we need to play both halves as brothers."
