Despite the Rhinos enjoying repeat sets on the Bradford line early on, it was the home side to break the deadlock.
Lee Gaskell’s chip towards the posts was collected by a leaping Mitch Souter, who wriggled his way over for his first try in Bradford colours.
The Bulls began to dominate proceedings but could not add to their early score and it would be the visitors who notched the game’s next try.
Sinfield’s towering kick into the corner bounced fortuitously back into the arms of Derrell Olpherts, who in turn found Luis Roberts.
The half ended with Bradford firmly in the ascendancy however, with Eribe Doro crashing over from close range, with Souter turning provider on this occasion.
The boot of Gaskell proved influential once again soon after, with Olpherts unable to claim Aidan McGowan was on hand to pounce for his first in the red, amber and black.
The Bulls began the second half in the same vein they started the first and quickly extended their advantage with back-to-back scores.
The first of which came from Jayden Myers, who superbly collected a pass one-handed and dived over in the right corner.
Souter then grabbed his second, with a trademark darting run from dummy half.
Leeds responded with a try from Olpherts after a cut out pass from Sinfield.
The final act came from Eliot Peposhi – who celebrated his permanent deal with a powerful effort in the right corner.
Bradford Bulls record impressive crowd
The game between these two bitter old rivals who contested the 2004 and 2005 Grand Finals as well as the 2000 and 2003 Challenge Cup Finals drew an impressive crowd.
Despite the game taking place in pre-season, a crowd of nearly 5,000 fans attended the game showing the huge value the fixture still has.
It was only in 2020 that Leeds Rhinos sold out Headingley Stadium for the first time since its redevelopment for a fixture against the Bulls as they provided the opposition on a special occasion celebrating the careers of Rob Burrow and Jamie Jones-Buchanan.
If the Bulls can continue to draw big crowds in 2024, it will certainly help their IMG score and their ambition to return to Super League.
