Jackson Wray’s two second-half tries powered Saracens into the semi-finals of the LV= Cup as they overcame a young Newcastle Falcons side at Allianz Park.
Back-row Wray forced his way over from close range on two occasions in the space of five minutes, adding to 21 points from the boot of young scrum-half Ben Spencer in a 41-8 victory.
Ben Ransom ran over for Saracens' third try of the afternoon on 65 minutes, sending them into next weekend's game in an unassailable position at the top of Pool 1.
Dean Richards gave debuts to four players but a try from Catterick was the only time they threatened the Saracens line in their second heavy defeat at Allianz Park this season.
Spencer gave Saracens the lead from the tee after five minutes and doubled the advantage with another penalty moments later which also saw Falcons lock Sean Tomes shown the yellow card.
Ill-discipline continued to be Newcastle’s downfall as they were penalised at the scrum on their own 22-yard line and again Spencer did not waste the opportunity for 9-0.
Newcastle then got themselves into the game, turning over a Saracens scrum to set Glen Young breaking away from the pack before passing to Catterick to go over in the left corner.
Spencer converted his toughest kick of the game on 20 minutes as Newcastle were penalised at the lineout – the 21-year-old showing off his power by clearing the posts from just inside Newcastle's half.
Joel Hodgson wasn’t to be outdone however, the fly-half making no mistakes with a penalty from the halfway line to bring the deficit down to four points.
Hodgson missed two tough kicks in quick succession though at the end of the first half and Spencer made the Falcons pay with a late penalty to send his side in 15-8 ahead at the break.
Saracens continued their momentum in the opening minutes of the second half and debutant Nick de Jager should have scored from Nick Tompkins' pass out wide but instead the South African knocked the ball on through the back of the try area.
Wray made up for the error soon after, bundling his way over from five metres out to put Saracens in the perfect position to run away with the win.
When he crossed the line again four minutes later, Spencer knocked the conversion through to extend the lead to 19 points.
But Saracens were not finished, and when Tim Streather broke through the Falcons' line he found Ransom behind him to score the home side's third try.
And Tom Jubb completed the scoring, going over in the final minute after another good break by Streather.
Newcastle return to Kingston Park for Friday's encounter with Newport Gwent Dragons with only pride to play for in this year's competition.
