Raith made a comfortable passage into the second round of Co-operative Insurance Cup after beating East Fife 4-1.
The hosts wasted no time in stamping their authority on proceedings when they took a sixth-minute lead through Gregory Tade's close-range header.
Second division side Fife were left rocking when Tade struck again just four minutes later, converting Stephen Simmons pass to make it 2-0.
And the onslaught continued when Rovers found themselves three ahead inside half an hour as John Baird finished from 12 yards.
Fife threatened a comeback when they reduced the arrears moments after the restart when Robert Linn curled in a free-kick.
But Jamie Mole ended the prospect of a fightback when he headed home a fourth in the second half to seal the win.
