According to new guideline, coming into effect from October 1 this year, former Indian captain MS Dhoni will have to alter his bat size. Dhoni along with big hitters like David Warner, Kieron Pollard and Chris Gayle are the ones who play with bats with edges beyond 40mm as of now. According to the new guidelines, bats will also be limited to 108mm in width and 67mm in depth, apart from the 40mm edges. As per report, Pollard has already started using the bat and played with the same during IPL 10. The cricketer said sooner or later he'll have to followed the new specifications, therefore it's better using it from now on.
