The Fingerpost fighter was on the front foot from the outset, bossing and bullying his smaller opponent and picking his body shots.
Fighting back up at super-middleweight for this one, Murray was untroubled throughout against the 33-year-old Berlin-based Armenian, who had only lost three of his 22 paid bouts prior to tonight.
Murray, who has not boxed since winning a bruising encounter against Gabriel Rosado in April, has been working with Jamie Moore due to his long-time trainer Oliver Harrison’s illness.
He had no trouble imposing himself on Torosyan and it was the shape of things to come when he clearly hurt his opponent with a body shot towards the end of the second round.
It was back to the body again at the start of the third, before a cracking right hand over the top rocked the Armenian.
Torosyan tried a bit of show-boating in return, trying to give the impression that he had not been hurt, but Murray kept coming forward, sticking to his gameplan.
With those body shots visibly weakening his opponent, Murray’s onslaught was relentless with his constant barrage to head and body taking its toll.
And in the closing seconds of round four Murray launched a punishing right hand to the ribs to knock the stuffing out of Torosyan.
