SAINTS are out of the Ladbrokes Challenge Cup following a 47-18 defeat by Hull FC.
The visitors ran in eight tries to secure their passage to the next round.
Saints were surprisingly 25-12 down at half time after opening the scoring.
Keiron Cunningham’s men made the best possible start when they crossed following a period of solid defence.
It came in the fifth minute; Luke Walsh’s kick winning a repeat set before Jonny Lomax offloaded to Mark Percival who showed great strength to go over.
But Hull hit back in five minutes later through Danny Houghton who caught Leon Pryce’s line pass.
Scott Taylor then crossed on FC’s next attack to give them the lead – before Gareth Ellis increased it further following Marc Sneyd’s 40:20.
Saints toiled in the heat to make any impression on the visitor’s line but did have some relative success as the half entered its final 10 minutes.
Theo Fages was unlucky with a kick through and LMS did lift the forwards with some strong runs.
And it was the latter’s effort, thanks to great work from Morgan Knowles, that got Saints back into it.
The Londoner taking two over the line with him.
But the joy was short-lived as Jamie Shaul danced over as the half came to an end.
Sneyd adding a drop goal as the hooter sounded.
Saints needed a strong start to the second half – but they were almost handed a nightmare when the video referee was asked to adjudge a Hull try.
It was disallowed for a knock on and within seconds – after some magnificent defence from Lomax which stopped a certain Fetuli Talanoa try – Luke Walsh went over from distance.
The move started in Saints’ own half and featured a wonder offload from Atelea Vea before the scrum half did the rest.
Saints had their tails up but a penalty right in Hull territory handed the momentum back to the visitors.
And they made Saints pay, working the ball down the right hand side for Naughton to cross.
Sneyd restored the 13 point gap on 57 minutes from a penalty but that came after the officials missed a knock on right on Hull’s 20 metre line.
It seemed to knock the stuffing out of Saints too as in the 66th minute Kirk Yeaman crossed after the home side had failed to deal with a high ball.
Two minutes later Scott Taylor grabbed his second too – stretching over under pressure.
And Talanoa grabbed a worldie at the death to seal the deal.
