South Africa were guaranteed the number-one position on the ICC Test Championship table at the 1 April cut-off date, after victory in the Cape Town Test against Pakistan meant they couldn't be overtaken by their closest rivals - England, Australia and India.
South Africa entered the series on 124 ratings points and only needed to draw the series to retain the Test mace. But victory in the Cape Town Test by four wickets meant even if they loses the third and final Test at Centurion, it will still gain one ratings point, which will be more than sufficient to give them the top spot, irrespective of how the India-Australia and England-New Zealand series pan out.
If England win all three Tests against New Zealand, the maximum they can achieve is 119, while India can rise to as high as 112 (if they defeat Australia 4-0) and Australia can move to 121 (if they win all four Tests against India).
The Proteas will not only retain the prestigious Test Championship mace but will also earn US$450,000 for this achievement. This is a significant increase in prize money, as, until last year, the side topping the Test or ODI Championship table received US$175,000.
While South Africa have sealed the number-one spot, the battle for second, third and fourth positions is still on, and is not only intense but close, as only 13 ratings points separate second-ranked England from fifth-ranked India.
The side that claims second position at the 1 April cut-off date will earn US$350,000 while the side finishing third will collect US$250,000 and the side ending fourth will win US$150,000.
Meanwhile, Pakistan have gained in the Test Player Rankings despite suffering defeat against South Africa. Younus Khan, who scored 111 and 14, has returned to the top 10 in ninth spot after rising two places, while Azhar Ali's total aggregate of 69 runs has earned him 11th spot.
Asad Shafiq, however, is the biggest mover inside the top 50 in the latest player rankings. The 27-year-old from Karachi, who scored 111 and 19, has jumped 12 places to join England's Ian Bell in 16th position. Asad is now Pakistan's fourth batsman inside the top 20 as Misbah-ul-Haq is in 12th position (down by two).
South Africa's Robin Peterson, who scored a crucial 84 in the first innings, has rocketed 44 places to claim 100th position. Faf du Plessis in 33rd (up by one place), Vernon Philander in 85th (up by three places) and Dean Elgar in 86th (up by six places) are the other home side batsmen to make upward movements.
Hashim Amla, who scored 25 and 58, has retained his number-one ranking. while fourth-ranked AB de Villiers, who scored 61 and 36, has achieved a career-best rating of 851 to lead fifth placed Kumar Sangakkara by nine ratings points but still trails third-ranked Shivnarine Chanderpaul by 28 ratings points. Australia captain Michael Clarke remains second.
In the rankings for Test bowlers, Pakistan's Saeed Ajmal has returned to the top three in third spot. Saeed had match figures of 10 for 147 for which he has been rewarded with 58 ratings points. This not only given him a career-best ratings to date of 847 but also a jump of two places.
Saeed now trails second-ranked Philander by 42 ratings points. Philander collected 32 ratings points for his figures of five for 59 and four for 40. Dale Steyn is sitting on top of the tree, 18 ratings points ahead of his new ball partner.
Pakistan's Mohammad Irfan, who took three wickets in the first innings of the Cape Town Test, entered the table in 95th position.
In the rankings for all-rounders, Jacques Kallis swapped places with Bangladesh's Shakib Al Hasan, who reclaims the number one position.
