Ashes: Peter Siddle refuses to criticise England's Stuart Broad for standing his ground STUART Broad resumes tonight as the villain of the first Test, but Peter Siddle has refused to condemn his opposing fast bowler. "How many people have ever walked?," Siddle mused after Broad's extra-ordinary escape on the third day at Trent Bridge. Asked if he had ever seen a thicker edge given not out, Siddle replied: "Not much we can do about it, is there. I don't know, probably in the backyard maybe off my brother. The furore created when Broad was given not out caught at slip late on the third day overshadowed the home side's increasingly dominant position. England was already 232 ahead when umpire Aleem Dar made what will be the howler of the series, failing to see a thick edge off Ashton Agar's bowling which flew from Brad Haddin's gloves to Michael Clarke. By stumps England's lead was 261 with four wickets in hand and two days to play. There had been only one greater last innings run chase for victory in the history of Trent Bridge. England ran down 284 against New Zealand in 2004. Siddle claimed the frustrating events of day three were all part of cricket. It is the umpire's decision and you just take it and that's what we did. We just have to work harder tomorrow morning," a philosophical Siddle said. Siddle held back from criticising either Broad or the umpire's decision. You finish the over and go through to the next over. If you watched out there, there wasn't a big deal made of it. We got stuck in and just kept working to get the wicket. Asked about the role the Spirit of Cricket should play when a player has so obviously hit the ball and is given not out, Siddle replied: "The umpires make the decisions and the players stick with it. Nor did he want to debate whether the video umpire should have become directly involved. I am the player, I'm not the one who writes the laws. I guess you should ask the question to them (the International Cricket Council). Obviously people are going to be frustrated but it's hard out there for players and umpires. It is a long day and tough day for everyone out there. Things are going to happen but they are part of the game and we just have to deal with it. Spectators will have to understand that. There are times when stuff like that happens. We can't be blaming anyone. Siddle also refused to concede that Australia had wasted their two referrals, particularly a leg before wicket appeal against Jonny Bairstow which was clearly not out. You can't do anything about that. You use them because you think you're going to get a result early on and you don't," Siddle said. "You can't just hold them and put them in the back pocket and say `I'm going to get one in the afternoon" and save it for that. You use them when you think there's a chance of getting a wicket and that's what they're there for.
