Mohammad Hafeez and Asad Shafiq, who also scored centuries in the Chittagong Test, have also made upward movements. Hafeez has gained 12 places and is now in 47th position, while Asad has moved up 20 places to claim 63rd spot.
Bangladesh's Nazimuddin, who scored 31 and 78 on his debut, has entered in 64th position.

The 21-year-old Bracewell had figures of 3-20 and 6-40 which turned out to be the cornerstone of New Zealand's first Test victory in Australia in 26 years.
Bracewell is now New Zealand's third highest-ranked bowler after Daniel Vettori (seventh) and Chris Martin (up by one place to 16th).
The other notable bowlers from the Hobart Test obart to improve their rankings are Australia's new ball pair of James Pattinson and Peter Siddle.

The bowlers' list is headed by South Africa's Dale Steyn with England's James Anderson second and Morne Morkel of South Africa third.
Australia opener David Warner is the biggest mover in the Reliance ICC Player Rankings for Test batsmen as his unbeaten century in Hobart has lifted him 131 places to 70th position. Warner, adjudged man of the match, carried his bat while scoring 123 runs that came off 170 balls and included14 fours.
The other batsmen to head in the right direction from the Hobart Test are all New Zealanders and include captain Ross Taylor, Dean Brownlie and Kane Williamson.
Taylor, who was New Zealand's top scorer in the second innings with 56, has gained two places and is now ranked 21st while Brownlie has moved up 12 places to 55th position after scores of 56 and 21. Williamson contributions of 19 and 34 have helped him move up six places to 68th spot.
Meanwhile, South Africa and Sri Lanka go head to head in the three-Test series at Centurion from Thursday with both the sides eyeing upward movements.
South Africa currently sits in third position on 116 ratings points, one behind India, while Sri Lanka is in fifth spot, 17 ratings points behind.
If South Africa wins the series by 2-0 or better, it could leapfrog India into second position, while Sri Lanka's victory by 1-0 or better might put it ahead of Australia in fourth position. The teams ranking on the Championship table will largely depend on how the Australia-India series pans out.
