adopted a naturally high grip where both hands were closer to the end of the handle for more top hand control. Gilchrist successfully kept wicket for fast bowlers Glenn McGrath and Brett Lee for most of his international career. His partnerships with McGrath and Lee are second and fourth respectively in both test and ODI history for the number of wickets taken. With Alec Stewart and Mark Boucher, he shares the record for most catches (6) by a wicketkeeper in a ODI match, having achieved this feat five times. In 2007 he took six dismissals and scored a half century in the same ODI for the second time; he remains the only player to do so even once. At Old Trafford in August 2005, he passed Alec Stewart's world record of 4,540 runs as a Test wicketkeeper, and at his retirement in 2008, he was the most successful ODI wicket-keeper with 472 dismissals (417 catches and 55 stumpings), more than 80 dismissals ahead of his closest rival, Mark Boucher. This record was surpassed seven years later by Kumar Sangakkara. Walking and discipline It is unusual for professional batsmen to "walk"; that is, to agree that they have been dismissed and leave the field of play without waiting for (or contrary to) an umpire's decision. Gilchrist reignited this debate by walking during a high-profile match, the 2003 World Cup semi-final against Sri Lanka, after the umpire ruled him to be not out. He has since proclaimed himself to be "a walker", or a batsman who will consistently walk, and has done so on numerous occasions. On one occasion against Bangladesh, Gilchrist walked but TV replays failed to suggest any contact between his bat and the ball. Without such contact, he could not have been caught out. Gilchrist's actions have sparked debate amongst current and former players and umpires. Ricky Ponting has declared on several occasions that he is not a walker but will leave it to each player to decide whether they wish to walk or not. While no other Australian top-order batsmen have expressly declared themselves to be walkers, lower-order batsmen Jason Gillespie and Michael Kasprowicz both walked during Test matches in India in 2004. In 2004, New Zealand captain Stephen Fleming accused Gilchrist of conducting a "walking crusade" when Craig McMillan refused to walk after Gilchrist had caught him off an edge from the bowling of Jason Gillespie in
