In contrast, Bangladesh traded places with Scotland after the drawn four-match series against Zimbabwe saw them concede five points and drop to 11th position, while Zimbabwe retained their 14th spot, despite collecting four points.
With only eight points separating top-ranked West Indies from eighth-ranked India, the ICC World T20 in India is shaping up to be an open event with any of the top-ranked sides capable of lifting the trophy in Kolkata on April 3.
