South African Hashim Amla can become the highest-ranked batsmen in the world when the second Test against Australia begins on Thursday.
Amla currently trails Kumar Sangakkara by four ratings points and can surpass the Sri Lankan star with a big score against Australia.
The 29-year-old is already rated as the best one-day batsmen in the world, but could hold both the Test and ODI titles concurrently if he can continue his impressive recent form.
Amla made 104 and 38 in the opening Test in Brisbane and heads to Adelaide with the chance of overtaking Sangakkara on top of the rankings.
There could be a change at the top of the bowling rankings as well, with South African duo Dale Steyn and Vernon Philander battling it out for the premier position.
Steyn currently holds a 19-point lead on top, but Philander could overtake his compatriot with a good performance.
Meanwhile, Jacques Kallis overtook Bangladesh’s Shakib Al Hasan at the top of the all-rounder rankings.
Al Hasan scored 91 runs and took two wickets when Bangladesh lost to the West Indies by 77 runs last week, but that saw him drop 21 ratings points and lose top position to Kallis.
There weren't too many changes at the top of the batting and bowling ratings in the new rankings released on Monday.
England captain Alastair Cook rose four places in the batting rankings to seventh following his 176 against India, while Pakistan duo Younus Khan and Azhar Ali dropped a place each to be eighth and ninth respectively.
The biggest mover was Cheteshwar Pujara, who jumped up 35 places to 24th position following his unbeaten 206 against England.
Pragyan Ojha made the biggest leap of the bowlers with the Indian moving up nine places to fifth.
England's Stuart Broad dropped five spots to 13th, while Kiwi Tim Southee moved up 10 places to be equal 30th.
