Saints got their semi-final charge off to a perfect start as they beat Castleford 26-12.
Justin Holbrook’s men handed the Tigers their first defeat of the year on their own midden – and rose to third in the Betfred Super League in the process.
James Roby bagged a brace in an excellent performance, suitably aided by the outstanding Luke Thompson and, in the second half, the returning Matty Smith.
If they say defence wins Championships too then the display also sent a message to the rest of the league that Saints are well in the hunt.
Tenacious and desperate at times it halted the Tigers’ marauding attack and laid the platform for some scintillating tries.
That attitude was more than evident in the first 10 minutes when they stopped Cas scoring on back-to-back-to-back sets.
Zeb Taia then broke the deadlock with a try of real quality.
The potent left hand side had already looked lively in the opening stages and it was a fine pass from Theo Fages that set the big second rower off – dancing through tackles and stepping the full back on his way.
Mark Percival then knocked over a penalty to make it 8-0 and Saints were unlucky not to have increased the lead further.
Kyle Amor touched down a ball that ricocheted but it was called back for a knock on that not many in the ground saw.
Cas then had one chalked off by the video official for offside before Saints defended their way out of trouble on numerous occasions.
Ryan Morgan’s last gasp tackle on the line typifying the approach.
That continued in the second half until Cas gained good field position on the back of penalties and astute kicking from Paul McShane.
Adam Milner burrowed over from close range and Luke Gale, who was quiet throughout, tagged on the conversion to make it game on.
But Saints hit back with a moment of real class.
The ever improving Morgan Knowles made a wonderful break in midfield and drew his man to get Thompson away.
Fages was next up, but a simple pass from Smith found a darting James Roby who flew in under the sticks.
More defence followed – Lomax stopping a certain Jy Hitchcox try with a wonder tackle on 60 minutes – before Saints scored again.
Thompson was again at the hub; clearing his lines and winning a penalty before some superb offloads from Taia and Jon Wilkin saw Smith produce a slide rule kick for Lomax to win the race.
Joel Monaghan pulled one back with an acrobatic finish in the final stages but anything other than a Saints’ win would have been a travesty.
So when Roby darted over once again in the final minute it was celebration time.
Even though the video ref took an eon to give it!
