Glenn Maxwell says fielder's word should be good enough for umpire's to give a catch out Jos Buttler thought he caught David Warner, but the third umpire had other ideas. THE AUSTRALIAN team still subscribes to the Ricky Ponting theory that a fieldsman's word should be good enough when it comes to claiming controversial catches. The issue has reignited after England wicketkeeper Jos Buttler claimed a low catch off David Warner's edge in the 14th over of the opening one-day international at the MCG on Sunday evening. Warner walked only for the dismissal to be reversed by the third umpire. Man-of-the-match Aaron Finch, who was batting with Warner at the time, supported Buttler's actions while England captain Alastair Cook declared "I thought it was a pretty clean catch." The day after the match, Australian batsman Glenn Maxwell suggested catches should only be referred if the batsman objected. "I think Davey was pretty convinced he was out," Maxwell said. He was about a metre away from jumping over the rope I think there's a little bit of a grey area there. I think it's got to be if you take the fielder's word and the batter's happy to go, that's where it's got to be left. If the batter wants to stay then that's when it should go up there (for a video review). I think Davey was pretty happy to walk off and happy it was caught. It looked like it was probably out to me as well. Warner, who was on 22 at the time of the disputed catch, went on to score 65 and combined with Finch to make a match-winning 165-run opening stand. Former Australian captain Ponting attempted to introduce a convention during his stewardship where batsmen accepted the word of a fieldsman when he claimed the catch.
