Manly have all but ended Canberra's finals hopes with a 36-22 win in their NRL clash at Canberra Stadium.
The Sea Eagles edged one step closer to locking down a top four finals berth, while the 12th-placed Raiders are now only a mathematical possibility of making the top eight due to their poor for-and-against record.
Minus star players Terry Campese, Blake Ferguson and Jack Wighton, the Raiders capped off a tumultuous week, in which coach David Furner was sacked, by slumping to their fourth straight loss.
Manly flew out of the blocks with four first half tries, three of which were through some brittle Raiders edge defence.
Manly playmakers Daly Cherry-Evans and Kieran Foran were superb, throwing the last pass or kick in the majority of their side's six tries.
