Australian Rules Grand final: Geelong ended their 44-year wait to clinch the premiership with an emphatic annihilation of Port Adelaide by 119 points in the Grand Final in front of 97,302 spectators at the MCG on Saturday afternoon.

The Cats were simply devastating as they destroyed the Power by a record Grand Final margin, eclipsing the former record of 96 points held by Hawthorn since their defeat of Melbourne in 1988.

The Cats outplayed the Power and kept the interstate visitors to a mere six goals for the game - only two of which were scored after half-time.

To top off the afternoon - and to add to the numerous accolades the Cats have already snared this year - forward Steve Johnson was awarded the Norm Smith Medal for man of the match.

It was a match that was won in the first half, with the Cats shrugging off the physical pressure the Power applied to answer strongly on the scoreboard.

With 11 goals to four on the board at the first change, the Cats cruised to their final winning margin of 24.19 (163) to 6.8 (44).

Paul Chapman was electric in the first quarter, ended the day with four goals and 21 possessions and took a spectacular mark over Warren Tredrea in the third term.

The sting of the match was gone after half-time and it turned into a complete procession for the Cats.

They lined up to kick goals and the responsibility was shared around, with 11 individual goal-kickers dominating Port's defence.
