Melbourne's Paul Roos era is off to a perfect start, with the Demons upsetting Richmond by 14 points in their AFL pre-season match.
Recruit Jay Kennedy-Harris starred with three last-quarter goals as the Demons stunned the Tigers 1.13.11 (98) to 1.10.15 (84) on Friday night at Etihad Stadium.
Adding to a poor night for Richmond, veteran utility Chris Newman hurt his knee in the third term.
Newman had kicked two goals before he hyper-extended his knee in a marking contest during the third term.
He was able to gingerly walk off the field without help, but went straight to the rooms.
Richmond made an embarrassing and costly start to the last term when they had 19 players on the field.
The interchange infringement cost them a goal.
The Tigers were pressing late in the match when David Astbury cramped and shanked a centering kick.
Kennedy-Harris pounced and took a couple of bounces before he goalled to ice the match.
Jeremy Howe then finished off with his fourth goal.
While it was only their first pre-season game, Melbourne showed great signs under Roos' coaching after their calamitous last few seasons.
They had an astounding 445 possessions to Richmond's 262.
Their ball movement looked much more fluent and there was no drop-off in workrate.
"The win is sort of irrelevant but perhaps for a group that has been pretty fragile it gives them a bit of confidence so its probably pretty important that we hung on in the end," Roos said.
Melbourne won despite being without key forwards Chris Dawes, Jesse Hogan and Mitch Clark, who are coming back from injury.
Richmond coach Damien Hardwick said they are hopeful Newman has only jarred his knee.
"He landed a little bit awkwardly, but we'll fine out more in the next couple of days," Hardwick said.
"He's up walking around, so we're hoping it's jarred."
Hardwick added he was unsure why Richmond had an extra player on the field at the start of the last quarter.
"That probably summed up the night," he said.
Hardwick became animated with his players at three-quarter time and said it was because they lacked intent.
