St Helens stormed back to the top of Super League with a crushing nine-try demolition of Hull KR, whose slim hopes of joining Saints in the Super 8s were extinguished in clinical style.
Saints went 24-0 up with a burst of attacking brilliance yielding four fine tries, before a Rovers fightback halved the deficit before the break.
Adam Quinlan's 70m try made the game safe for Saints early after the break.
And Mark Flanagan, Joe Greenwood and Adam Swift added more gloss for Saints.
Six league places separated the sides before kick-off and the opening stages confirmed the gap in class between the teams, with the Hull KR defence - just - holding firm in the face of some fierce Saints play with ball in hand.
But, when the dam finally burst on 15 minutes, the scores racked up quickly for St Helens, with Greenwood breaking through three tackles to open the scoring.
|Super 8s settled|
|The result means the eight teams who have qualified for the Super 8s are now confirmed, with Catalans Dragons sealing the final slot||St Helens, Leeds, Wigan, Huddersfield, Castleford, Warrington, Hull FC and Catalans Dragons are all in the Super Eights|
|Hull KR needed to win, for the Dragons to beat Leeds on Sunday and for an unlikely 73-point swing in their favour to make the top eight||The Robins will now go into the Qualifiers against the top teams from the Championship in order to keep their place in Super League|
With the next attack Travis Burns finished off a classic attack, before a brilliant Luke Walsh cut-out pass created the third try out wide for Matty Dawson.
Atelea Vea powered through some weak defence after a fine 40/20 kick from Burns set up the position and the scoreboard took on an ominous look for the visitors.
A comeback of sorts was sparked by Kieran Dixon's opportunistic effort and arguably the try of the night from John Boudebza, but any hope of a genuine contest was ended a few minutes into the second half when Greenwood raced from deep in his own half to open up a commanding lead again.
A rapidly tiring Hull KR side leaked a further four tries in the closing 25 minutes, as Saints made their class tell with Greenwood and winger Swift both grabbing braces and Flanagan scoring his first try of the Super League season.
