The Sky Sports pundit was not only at York Hall to see the Welshman scoop £32,000 and the light-welterweight title, but he also backed him to win.
McCrory and colleague Johnny Nelson are going head-to-head for charity by predicting the outcomes of the major fights, usually live on Sky Sports.
The pair are donating their winnings to Children With Cancer and UK Parkinsons respectively, but it is the former that is ahead on the cards.
McCrory had taken the first round by backing Anthony Crolla to beat Gavin Rees and doubled his lead this week by predicting Wales would be smiling thanks to Jenkins.
"What can I say, I've won again!" said McCrory. "I am delighted because the Prizefighter line-up was made of guys we hadn't heard of or seen.
"There is usually a bit of luck involved, especially if Johnny Nelson picks a winner, but Jenkins was good. Very good."
Unsurprisingly, both pundits predicted a revenge win for David Price against Tony Thompson which meant that Prizefighter was the decider.
The eight boxers were far from famous but McCrory's man Jenkins won all three fights with ease while Nelson's pick, Liam Shinkwin, was beaten in the first round.
It mean McCrory came out on top again and is now 2-0 ahead - and with £200 up for grabs every week, he has doubled the prize money!
This weekend, we have Olympic hero Luke Campbell making his pro debut in front of his home fans in Hull, Anthony Ogogo in action, Kell Brook facing Carson Jones again and Derry Mathews taking on another local lad, Tommy Coyle!
