1970 Grand Final before a record crowd of 121,696, Carlton full forward, and giant of the game, Alex Jesaulenko, took one of the most inspirational marks in the history of 'the Australian game.' Leaping high for a specky over Collingwood's Graeme Jenkin just before half time, the mark inspired a Carlton side that was behind by 44 points at the half. It was retroactively classified as the Mark of the Year. Sydney's Leo Barry leapt into history with his match-saving mark in the final seconds of the 2005 grand final against the West Coast Eagles to seal the game. His contested overhead mark was taken in a congested pack of three teammates and three opposition players. Shaun Smith's and Gary Ablett's shared title of Mark of the Century. St Kilda/South Melbourne player Roy Cazaly was renowned for his high marks, giving rise to the catchphrase and song "Up There Cazaly". Spoiling the mark Spoiling is the technique typically employed by opposition defenders to legally stop a player from catching the ball. It is performed as a punching action by hand or fist just before the opposing player has caught the ball in their hands. The rules are quite strict on defensive spoiling methods. Players are not allowed to push other players out of marking contests or make forceful front on contact with an opponent in a marking contest, if they are not simultaneously attempting to mark or spoil the ball. Also, no high contact is allowed unless such contact is incidental to attempting to mark or spoil the ball. Taking the arms Deliberately taking, hacking or chopping the arms is an infringement committed by players which will result in a free kick. The arm interference free kick was introduced as a specific free kick in the AFL and its affiliates in 2005, although it was paid as a blocking, striking or holding free kick previously. The free kick was designed predominately to make it easier for forwards to take contested marks by not allowing defending player to punch or pull a marking player's outstretched arms in a marking contest. The rule was introduced by the AFL amidst on-going calls from fans and commentators to take action against the defensive tactic of flooding. The rule does directly limit the effectiveness of defenders, but the AFL has never stated whether or not flooding was the reason for the change. Marking-related injuries Marking
