Similarly to two nights ago against Adelaide, the Breakers' radar was seriously askew in the opening minutes, starting two-of-12 from the floor to allow Melbourne to quickly seize a double-digit lead.
But, unlike the big win over the 36ers, there was no revival. By the end of the quarter, they had yet to make a single three-pointer after seven attempts, being held to just 13 points in the first 10 minutes.
Melbourne's advantage stood at 19 points after a half in which very little went right, with the 53 points the Breakers ceded the most by far this season.
The second half was better - it could hardly have been worse - but by then the damage was done. Any signs of an attempted comeback were quickly
curtailed by a defence than waved through their opponents with worrying frequency.
Gone was the suffocating defence that held Perth and Adelaide to tip off the season, replaced by a unit that allowed far too many open looks. Daniel Kickert, in particular, couldn't believe his luck at being left alone from beyond the arc, draining his first four from deep to make the Breakers' own inaccuracy even more damning.
The Breakers also struggled with their fouling - another call-back to last year - and by sending Jordan McRae to the line 12 times, they allowed the import to pour in 31 points.
There were no such masterful efforts from the Breakers' best. Corey Webster again led the scorers with 21 points but he was among the chief culprits in his side's wayward performance from deep, making four but taking 12 attempts.
Cedric Jackson chipped in with eight points, nine rebounds and six assists but he never threatened to take hold of the game like he had in patches of both the Perth upset and the Adelaide thumping.
On a rare positive note, Tom Abercrombie made his first start of the season, grabbing nine points in 25 minutes, while the Breakers would have also liked what they saw from a limited Alex Pledger, scoring 13 in as many minutes.
There will need to be plenty more contributions like Pledger's when the Breakers host Cairns at the NSEC on Thursday night.
