ISLAMABAD Pakistans fast bowler Mohammad Aamir has rocketed into his career-best 17th position in the ICC Player Rankings for Test bowlers after playing lead role in his sides four-wicket victory over England in the Oval Test. According to fresh ranking of International Cricket Council (ICC), Man of the match Aamir took 1-49 and 5-52 respectively in the first and second innings in the Test and was awarded with a jump of 14 places in the rankings, which puts him just behind Paul Harris of South Africa and makes him the third Pakistan fast bowler in the top 20. Aamir has played a total of 13 Tests in which he has taken 45 wickets. As such, he is still in the qualification period for bowlers as a bowler qualifies for a full rating when he reaches 100 Test wickets. This means he could potentially edge closer or even overtake 14th-ranked Jerome Taylor of the West Indies depending on how he performs in the fourth and last Test, which starts at Lords from Thursday. Aamir now trails Taylor by six ratings points after earning 91 ratings points from The Oval Test. Off-spinner Saeed Ajmal, who took 4-71 in the second innings after bagging 1-32 in the first, has also jumped nine places to claim a career-best 48th position while Wahab Riaz, who took 5-63 and 1-40 on his debut Test, has entered in 60th position. For England, off-spinner Graeme Swann has moved up one place to regain his second position on the bowling chart. Swann, who had match figures of 7-118, had first climbed to second position in March this year after the first Test against Bangladesh in Chittagong. Swann, who took his 100th Test wicket in the first innings when he caught Yousuf off his own bowling, earned 24 ratings points that has put him on a career-high 820 ratings points. However, James Anderson has fallen one place to fifth position, Stuart Broad has dropped three places to 11th spot and Steven Finn has slipped three places to 35th position. In the ICC Player Rankings for Test batsmen, Pakistans Mohammad Yousuf, Umar Akmal and Azhar Ali, and Englands Alastair Cook and Matt Prior all rose up the rankings. Yousuf, who scored 56 and 33, has climbed two places to 14th position with Indias Gautam Gambhir firmly within his sights, Umar has jumped six places to share 41st position with Australias Phillip Hughes and Azhar has vaulted 28 places to 55th spot. England opener Cooks century in the second innings has given him share of 28th position with Ramnaresh Sarwan of the West Indies while Prior has gained two places to rise to 33rd position following his knock of 84 not out in the first innings. Batsmen losing ground in the latest rankings are Kevin Pietersen on 21st (down by one place), Andrew Strauss on 23rd (down by two places), Paul Collingwood on 30th (down by seven places), Kamran Akmal on 49th (down by four places) and Eoin Morgan on 64th (down by seven places).
