DRS was meant to stop mistakes but it's not happening: Ponting

Australian skipper Ricky Ponting is not too impressed with the newly-introduced Decision Review System for close dismissals as he feels the innovation has not been able to cut down on umpiring errors in the ongoing Test series against the West Indies.

Ponting said he was left flummoxed when the third umpire ruled West Indies batsman Shivnarine Chanderpaul not out in the ongoing second Test despite video evidence to suggest otherwise.

"The new system was meant to stop this sort of thing happening but it didn't," Ponting was quoted as saying by The Australian after the opening day's play in Adelaide.

Chanderpaul, who made 62 runs, was on 38 when he seemed to have edged one to the keeper but umpire Mark Benson ruled him not out, prompting Ponting to call for a review.

But to the Australian skipper's surprise and dismay, the third umpire backed Benson's decision.

Ponting went up to Benson to ask why Chanderpaul had not been given out before approaching fourth umpire Bruce Oxford during a drinks break.

"I wanted to know why the appeal had been turned down. I was keen to find out what technology had been used to make the decision because the umpires on the field had not been told.

"We didn't know what hotspot had shown or whether they had used snicko because there was definitely a noise. Hotspot will only show a mark on the bat if the edge is facing towards the camera," Ponting explained. Even West Indies captain Chris Gayle had criticised the system after the first Test.
