WELLINGTON, Feb. 2 (Xinhua) -- The all Africa quarter final of the international rugby sevens world series in Wellington Saturday saw Kenya and South Africa in a neck-and-neck battle that went right up to the final whistle.
Kenya, who made a clean sweep of their pool Friday, was first off the mark with Collins Injera putting the ball over in the third minute, followed by a Biko Adema conversion.
A determined South Africa battled back and dominated the rest of the first half with two consecutive tries from Cornal Hendricks and a third from Stephan Dippenaar.
Although Philip Snyman missed all three conversions, South Africa ended the first half with an imposing 15-7 lead.
Kenya's Willy Ambaka led the fight back in the second half with nifty footwork finding a gap in the South African defense to put the ball over the line, with Biko Adema making another valuable conversion.
South Africa's Chris Dry took his team's score to 20 with a fourth try, but Snyman's continued failure to find the posts ultimately proved costly.
In an almost identical move to his first try, Ambaka found another hole to run through in the fifth minute and put the ball over again.
But it was Adema's constancy with the conversions that nudged Kenya into lead and put the final score at 21-20.
Kenya goes on to face reigning champions New Zealand in the semi-final later Saturday, while South Africa will have a semi- final play-off against Australia who lost their quarter final match to New Zealand.
