The coach watched on as the Belfast fighter made it look easy in what was meant to be a real test at the Ulster Hall.
McComb took on Czech champion Miroslav Serban, a fighter that had impressed on his last visit to the City, playing his part in an entertaining fight with soon to be European title challenger Paul Hyland Jr.
The 28 year old battler was at the very least meant to bring the exciting new to the scene talent rounds.
However, the Belfast fighter handled what was meant to be a true test of his credentials with ease, stopping Serban before the 2 minute mark had past.
There were some, who questioned the stoppage, but the away fighter although tucked behind a guard failed to fire back under serious pressure.
That pressure applied was what really impressed Vaughan. The coach of McComb, Tyrone McCullagh, Paddy Barnes and Tyrone McKenna liked his charges reaction to the smell of blood and heralded the display as a mature performance.
“What impressed me most was when he hurt him he reacted like a fighter with 20 fights experience. He never let him off the hook, he put it on him, he cut the ring off and I think he was punch perfect tonight,” Vaughan told Irish-boxing.com before revealing ‘The Public Nuisance’ is settling perfectly into the pro ranks.
“What I see in the gym he is bringing into the ring and sometimes it does take fighters longer to do that. We have been working on those shots you seen tonight particularly that left hand up the middle.”
Vaughan also pointed out his charge is proving any pre pro doubters wrong and suggested his performance last Friday in the Ulster Hall proves he is a genuine prospect.
“Everyone said when he turned over he is six foot, he is just a skinny kid, but you seen there he is planting his feet and he is showing the power. He can punch with both arms- and as I said he showed that killer instinct. It was some performance and he will continue to build on that.”
