The ban slapped on star spinner Saeed Ajmal has left Pakistan’s cricket chiefs frantically trying to take action on “chuckers”, including dusting off expensive biomechanical testing kit that had laid unused for years.

Pakistan Cricket Board (PCB) chairman Shaharyar Khan acknowledged chucking was rife in the domestic game. “I was informed 25 suspected bowlers had been playing in our domestic cricket and now the number has increased up to 35 – that means every team has at least two suspected bowlers,” said Khan.

Former captain and ex-PCB director of National Cricket Academy (NCA) Aamir Sohail said there were warning signs for Ajmal.

“I had warned in February this year that Ajmal will be suspended because his action was deteriorating with age, but no one heeded. I had recommended his action be checked every year,” he said.

Former opening batsman Sohail, who played 47 Tests and 156 ODIs for Pakistan, said there had been a total lack of interest in dealing with bowlers with suspect actions. “We are ourselves to blame,” Sohail said. “We have a biomechanic lab in NCA which I activated and gave a list of bowlers to test there, but the lab remained ineffective for years.”

The NCA has equipment to test bowlers to check they are not straightening their arm more than the permitted 15 degrees in delivering the ball.

But the $440,000 (Dh161,000) kit, which includes 18 cameras supporting apparatus and computer software, has gathered dust since it was bought in 2009 as PCB chiefs dismissed the need for it.
