We also prevented Medicals from scoring a single point, and in doing so also closed the points difference gap on the two leaders – something which may still prove crucial when the end of season placings are calculated.
There are nine more games to play and 45 more points up for grabs as the title race hots up, but we do seem to be gaining momentum.
The defeat of Northern a week ago set the standard, and the form continued with a changed side in Newcastle. We came up against a home team which tackled well and looked to move the ball at every opportunity, but which lacked the power and precision of the visitors.
After a lively start by both sides it was West who took the game by the scruff of the neck with Peter Youll weaving his way over after skipper Ryan Painter had taken a quick tap penalty.
Zac Southern took over the kicking duties from Stu Waites, who is unwell, and slotted the first of five fine conversions.
He was on the mark again on the quarter hour after left winger Callum Johnston was sent in at the corner – Painter once again the provider from a scrum.
Medicals weren't prepared to buckle under, and would have got on the scorecard just before the half hour but for some superb defending from Will Hilditch.
Southern’s pass to Adam Coates was intercepted in his own half by stand-off Henry MacGinnis who looked to be going all the way. That was until a dramatic intervention from the speedy Hilditch brought him down just three metres from the line - forcing the home player to spill the ball.
That scare only served to galvanise West into putting on more pressure,which eventually told when a Medicals line-out ball evaded all the jumpers. The lively Scott Butcher collecting at the tail and shrug off the attentions of three defenders to go over and give his side a 21-0 lead at the break.
The four try bonus point was collected soon after the break. Our powerful scrum secured good ball and Hilditch drew the defence to send Mallinson in at the left corner with Southern just wide with his conversion attempt.
We brought on forward replacements Jake Linighan, Joe Rafferty and Craig Hadwen and in their first set-piece they drove the home pack backtowards their line - Butcher accepting the opportunity to touch down and give Southern an easy pot at goal.
The pick of the tries came on 72 minutes with a superb offload from Youll in the tackle sending Hilditch into space on the right. He found Mallinson making an inside run to cruise through a gap.
Southern made it 40-0 with his kick, but hit the post with his next attempt after winger Adam Peacock stepped inside his opposite number to touch down after West had quickly moved a penalty out to the right.
Medicals continued to work hard with their supporters desperate for what would have been a deserved score.
They thought they had it with three minutes left when we were penalised 30 metres out in front of their posts. However, centre Adam Heaps’ kick was wide to the right and collected behind his own line by Youll.
He promptly set off on a powerful run diagonally through the home defence which only ended close to the home 22 when he was finally caught by a desperate defender.
However, we were not to be denied as Medicals gave away a penalty which saw us once again move the ball smartly out wide where Mallinson claimed his hat-trick right on the final whistle.
