DUBAI, Jan 17: Pakistani off-spinner Saeed Ajmal brushed aside suspicions over his bowling action after wrecking England with career-best figures of 7-55 on the opening day of the first Test here on Tuesday.

The 34-year-old, whose claims to unveil a mystery delivery he called teesra surrounded the build-up of the threeTest series, helped Pakistan bundle out England for 192 on a slow turning pitch at Dubai Stadium.

Former England paceman Bob Willis raised suspicions over Saeed's action.

'The off-spinner is fairly orthodox. The delivery that I have a problem with is the doosra [second one],' Willis, referring to Saeed's delivery which turns the other way than the normal off-spin, while commentating on Sky Sports in England.

'The ICC has accommodated this delivery they changed the rules to allow these bowlers to bend their elbow 15 degrees which is what makes it so difficult for the batsmen,' said Willis.

But Saeed said he was not worried about his action.

'I am just focusing on my bowling. I don't know about that and it's the responsibility of the umpires and referee to check my action. I have bowled my best so I am happy, said Saeed whose action was questioned once in 2009.

'They did it to Saqlain Mushtaq,' said Saeed about the former Pakistan spinner, regarded as the founder of doosra.

'They are doing it with me now. Australia questioned my action [in 2009] but I see no problem with it.

Saeed said he did try to bowl his mystery delivery but hasn't perfected it.

'I did try to bowl that delivery [teesra] but I have not perfected it, have not full confidence in it so maybe I bowl it in the next two to three innings,' he said.

Saeed said he bowled wicket to wicket and got his reward. 'I just bowled wicket to wicket and that helped me a lot and I got four leg-before wickets, bowling wicket to wicket did not help me get spin but some bad shots gave me wickets.'-AFP
