That approach may change as his career moves on but the 19-year-old, who is coached by father Kali, was confident in his ability.
"That's my style," Meehan Jnr said. "It's very unorthodox and it worked; got the job done."
The teenager has sparred with one-time world title challenger Alex Leapai and had an impressive amateur career across the Tasman.
He made his NRL debut for the Roosters earlier this year and it's easy to draw the comparison to the code-hopping Sonny Bill Williams who has also dabbled in boxing, among his pursuits on the rugby and league fields.
"Sonny's a close friend of mine and he's helped me massively, just in the way he deals with crossing codes and every bit of advice he's given me has worked," Meehan said.
The youngster won't have to wait long until he laces up the gloves for the second time as a professional as he will meet a yet-to-be-determined opponent in Sydney on December 3.
That bout will come on the undercard of Australian middleweight Daniel Geale's match with Jarrod Fletcher.
Meehan plans to fight three times in the NRL's off-season and he said balancing both sports was a manageable task.
"The Roosters are really supportive, really helpful with everything I do, all the way from the players to the chairman of the board," Meehan said.
"I'm living my dream at the moment; playing professional footy, fighting professionally. So until I have to make a decision, I'm just going to enjoy every moment."
Meehan's win was the opening bout of tonight's cruiserweight Super 8 card that was headlined by a career-defining bout between Kiwi heavyweights Kali Meehan and Shane Cameron.
The younger Meehan, who was born in New Zealand but is a junior Kangaroo and identifies as an Australian in the boxing game, said it was a great moment to take his maiden professional fight on a card headlined by his father.
"It's special; it's really special."
There's sure to be plenty more special moments in Meehan's sporting career.
