Host South Africa registered a massive 83 runs victory over Bangladesh in the second and last T20 internationals at Senwes Park, Potchefstroom on Sunday.
With the win South Africa completed a clean sweep over the visitors in all three formats of the game in the series.
Earlier, South Africa, after being asked to bat first posted a mammoth total of 224/4 against a hapless Bangladesh bowling side largely thanks to a record-breaking century by middle-order batsman David Miller.
He smashed the record for fastest T20I ton on his way to reach the magical figure of 101* runs off just 36 balls.
