A historic win for Brendan Taylor's Zimbabwe team in ICC Test Ranking since May 2007 in the ninth place, ICC announced.
The two-match series ended in stalemate with Zimbabwe finishing at 34 ratings points, ahead of 10th ranked Bangladesh.
Zimbabwe had entered the series unranked and irrespective of the result of the series would have finished ninth on the table.
Zimbabwe had pulled out of playing Test cricket in January 2006 and, since its return to the Test arena in August 2011 after a gap of five years, it had been unranked, having not played the requisite eight qualifying Tests to be part of the rankings table.
In sharp contrast, Pakistan has conceded five ratings points and has dropped behind Australia and West Indies. Misbah-ul-Haq?s side had only moved into fourth position last month following the conclusion of the Ashes, which England retained after defeating Australia by 3-0.
