SA seal Twenty20 series win over Aus

Off-spinner Botha took 2-16 in his four overs,slowing the tourists8217; progress as soon as he came on to bowl in the middle of the innings.

Botha helped to build the pressure on the opposition batsmen and took the key wicket of opener Michael Clarke in the 11th over of the innings for a 33-ball knock of 27. The captain8217;s other victim was Cameron White,caught in the deep by J.P. Duminy for 23 with the score on 106 in the 16th over.

Eight balls earlier,man-of-the-match Roelof van der Merwe had grabbed the important wicket of David Hussey,caught at point by Herschelle Gibbs for 27 as he went for a big hit. Hussey had struck 88 for Australia in Johannesburg in Friday8217;s match.

Van der Merwe,making an impressive debut,claimed 1-30 and did well to hold his nerve against Hussey,who had hit him for a six and a four off the two balls preceding his dismissal.

Hussey and White added 38 for the fifth wicket,the biggest partnership of their team8217;s innings.
