The company behind Hot Spot, BBG Sports, has said the application of Vaseline to the edge of a bat has no discernible effect on the technology. A batsman would have to apply a whole centimetre of Vaseline to the edge of a bat for it to have any effect, the company said in an official statement.
A controversy over the system erupted when Michael Vaughan, the former England captain and now commentator, sent out a tweet that suggested India batsman VVS Laxman may have applied Vaseline to the edge of his bat, which helped him escape a caught-behind appeal on the second day of the Trent Bridge Test. England were convinced Laxman had nicked a James Anderson delivery, and though Snicko showed there was a noise as ball passed bat, Hot Spot did not show any deflection. Stuart Broadadmitted to checking Laxman's bat and said he found nothing. Broad also said the England players were not convinced Hot Spot picked up faint edges
