Melbourne win by 50 points
Needing one win from their final two games to confirm top spot on the ladder going into the finals, the Demons avenged their one point loss to the Saints earlier in the season and won comfortably.
St Kilda were in the game until the last 10 minutes of the first half, using their small fleet of players to win contested football and kick forward at every opportunity but physicality got Melbourne on top as they ground their opponents down with hard tackling.
During the second half St Kilda ran out of gas from their exertions in the first and the Demons took over despite their forwards struggling - with just Athol Webb firing to kick five of the side's 21.
It was a steadying victory after two close wins followed by a narrow loss the previous Saturday. After an even first half Melbourne kicked away with seven goals to four in the third term and six - including four to Neil Crompton - to three in the last.
Best were Barassi, Webb and Johnson. Beckwith (eye) was replaced by Carroll and Ridley (cramp) by K. Mithen both in the last quarter.
St Kilda 12.11 d. Melbourne 10.14
Goals - Wilkinson 5, Brenchley 2, Boyle 1, Lord 1, Rowan 1
Best - Wilkinson, Milner, Atkinson
