England pace bowler James Anderson has moved up to a career-best number three in the Reliance Mobile ICC Player Rankings.
The 28-year-old Lancashire seamer has overtaken India's Zaheer Khan after claiming six wickets in the second Ashes Test in Adelaide. His England team-mate Graeme Swann is currently second, with the table headed by South Africa's Dale Steyn.
Swann's five-wicket haul in the second innings of the Adelaide Test has moved him to within 14 ratings points of Steyn. A good performance in the third and fourth Ashes Tests could see Swann end the year in the number one position.
In the batting rankings, under-pressure Australia captain Ricky Ponting has slipped out of the top 20 for the first time since 2001. The Tasmanian has dropped 12 places to occupy 25th, his lowest ranking for nearly a decade.
Jonathan Trott has continued his rise up the rankings and now occupies sixth place after scoring 78 in Adelaide. The 29-year-old is the highest-ranked England batsman with vice-captain Alastair Cook who has climbed nine places to sit in 13th place, the second highest ranked Englishman.
Kevin Pietersen has made a huge leap of 12 places, replacing Ponting in 16th position, the Surrey batsman's mammoth innings of 227 in the Adelaide Test helped him to return to the top 20, a location he has not been in since August.
Australia's Mike Hussey has risen to 14th, while West Indies opening batsman Chris Gayle has dropped five places to 19th after his team's drawn series in Sri Lanka.
However, Gayle's team-mates Brendan Nash (43) and Darren Bravo (69) have both made in-roads on the rankings. Sri Lanka captain Kumar Sangakkara still heads the rankings with India's Sachin Tendulkar in second place.
There is no change at the top of the rankings for all-rounders with South Africa's Jacques Kallis still leading the field. However, Australia's Shane Watson has displaced England's Stuart Broad for fourth place after the 29-year-old Queenslander scored 108 runs and claimed 1-44 during the second Ashes Test.
