South Africa's AB de Villiers has reached the number-one batting position for the first time in his career where he has been joined by Australia captain Michael Clarke in the latest Reliance ICC Player Rankings which were released on Friday.
De Villiers' move to the top of the batting chart is due to a combination of his own good performances in the Hamilton and Wellington Tests, as well as Kumar Sangakkara's disappointing show with the bat against England in the Galle Test.
De Villiers scored 83 in South Africa's nine wickets victory over New Zealand in the Hamilton Test and then followed up with 38 and 68 in the drawn Wellington Test. These performances have helped him earn 35 ratings points which have given him a career-best rating of 821 and a lift of two places.
Sangakkara, who had entered the Galle Test as the number-one ranked Test batsman, scored nought and 14 in Sri Lanka's 75 runs victory over England. This meant the former Sri Lanka captain has dropped from 850 ratings points to 813 ratings point which cost him three places in the batting table.
Sangakkara is now ranked fourth but can regain the number-one spot if he performs strongly in the Colombo Test which starts next week as he trails the two number one-ranked batsmen by only eight ratings points.
Jacques Kallis, AB de Villiers' team-mate, has also slipped one position to third after managing just six runs in his only innings in Hamilton and then missing the Wellington Test.
So the fall of Kallis and Sangakkara has helped Michael Clarke regain the number-one position -a week before he leads his side in the three-Test series against the West Indies. It is the second time Clarke has headed the batting table after he first topped the batting list in August 2009 after he scored 93 against England in Australia's victory by an innings and 80 runs in the Leeds Test.
Apart from a reshuffle at the top of the order, South Africa's Hashim Amla has moved up two places to eighth after scores of 16 and 46 in Hamilton and 63 in Wellington, England's Jonathan Trott has jumped six places to ninth after scoring 12 and 112 in Galle, New Zealand captain Ross Taylor has gained three places and is now in 10th position after scoring 44 and 17 in Hamilton and 18 in Wellington while Sri Lanka captain Mahela Jayawardena has lifted seven places to 19th spot after scoring 180 and five in Galle.
Other batsmen losing ground include South Africa captain Graeme Smith in 12th (down by two), Alastair Cook in 14th (down by nine), Kevin Pietersen in 22nd (down by two), Matt Prior in 24th (down by two) and Brendon McCullum in 25th (down by one).
In the Reliance ICC Player Rankings for Test bowlers, South Africa's Vernon Philander has continued to climb up the chart. The fast bowler had figures of four for 70 and six for 44 in Hamilton and six for 81 and none for 29 in Wellington.
Philander has gained 148 ratings points which has not only given him a career-best rating of 764 but also led to a jump of 11 places which puts him in a career-best fifth position.
He is the third South Africa bowler inside the top 10 with Dale Steyn firmly holding the number-one position and Morne Morkel in 10th spot after slipping one place.
Sri Lanka's Rangana Herath is the other bowler to earn a career-best rating and ranking. The left-arm spinner took six for 74 and six for 97 for which he earned 92 ratings points which has put him on 752 ratings points and a seventh position in the bowling charts after a rise of six places.
In the Reliance ICC Player Rankings for Test all-rounders, Bangladesh's Shakib Al Hasan is in number-one position but New Zealand's Daniel Vettori has slipped two places to fifth spot which has put England's Stuart Broad and Australia's Shane Watson one place up in third and fourth spots, respectively.
Meanwhile, England finds itself in a must-win situation in the Colombo Test if it has to retain its number-one position on the Reliance ICC Test Championship table. England's victory will keep it ahead of South Africa by a fraction of a point but its failure to win the Test will make South Africa as the new number-one ranked side.
If England loses the series 2-0, it will drop from 118 ratings points to 113 ratings points - three points behind South Africa - while a 1-0 defeat will mean it will slip to 114 ratings points.
Australia will also be eyeing to gain, at least, one place on the Test Championship table when it takes on the West Indies in the three-Test series in Bridgetown on 7 April.
While a series win will put it ahead of India in third position, a 3-0 series win will put Australia on equal points with England on 113 ratings points (if England loses 2-0 to Sri Lanka). And when the ratings are calculated beyond the decimal point, then Australia will be placed above England in second position as it will have a rating of 113.10 against England's rating of 113.045.
The Test Championship table as well as the player rankings will now be updated at the conclusion of the Colombo Test.
