Ashes 2013: England and Australia join forces to back changes to review system Australia were criticised for their failure to use the review system properly in the first two Tests culminating in Shane Watson's wasted attempt to have a plumb lbw at Lord's overturned. But there was an improvement in the third Test and Clarke was spot on with his appeals yesterday. Firstly he called for a review when Joe Root was given not out after feathering an edge behind. Putting his faith in the much-derided Hot Spot, Clarke was rewarded with Root's wicket when a small mark showed up on his bat. Hot Spot had passed its first Test of the day, more than can be said for umpire Tony Hill, who missed the nick. Clarke's second review was less clear cut. Matt Prior was given not out to a ball swinging into his pads from Peter Siddle with Aleem Dar believing he had got a small inside edge. Hot Spot showed no mark and Hawk-Eye had the ball striking leg stump. Hot Spot proved more reliable on Friday, which will have been a relief to Warren Brennan, the owner of the machine who has been a central player in a media storm this week. Australian broadcaster Channel Nine yesterday stood by its story on Tuesday of silicone tape on bats fooling Hot Spot. The network reported on Wednesday the ICC was investigating the matter. The ICC denied that was the case and lawyers from the ECB demanded an apology over the suggestion Kevin Pietersen had deliberately used silicone tape. Channel Nine reported "concerns" "centred on Kevin Pietersen's dismissal" at Old Trafford. Brennan told the ICC last week he believed silicone tape can mask edges but has been told to provide more proof. Channel Nine angrily denied it accused Pietersen of cheating and the ECB remains at loggerheads with Australia's official broadcast partner ahead of this winter's Ashes. The report is not a fabrication. It is a case of don't shoot the messenger," said Darren Wick, head of Channel Nine news and current affairs. We were reporting the concerns of the inventor of Hot Spot, Warren Brennan, which he referred to the ICC. That is fact. There were conversations between him and Geoff Allardice where those concerns were raised. In that sense it is not a fabrication so I am prepared to stand by the story. Nobody accused Kevin Pietersen of cheating. It was the Kevin Pietersen dismissal that set alarm bells ringing because it was at odds with the rest of the technology. That set everything up and running. We highlighted the Kevin Pietersen incident because that is the one where people said what is going on.
