Goals: Ben White (2), Joe Sanderson (3)
Leeds were short of influential stars Liam Sutclife, Rob Mulhern and Elliot Minchella because of Super League call ups but they soon settled into their stride. Billy McDermott finished of a flowing move along the backline to score in the corner for the second try.
The third try came from good play by the halves Ben White and Joe Sanderson that created space for centre Jordan Harper to crash over from close range before a long range break from near the Rhinos own line was finally finished off by Tommy Brierley in the corner.
The final try of the first half came when Ash Handley broke through just inside his own half and fed Walters, who finished off next to the posts to leave it at 24-0 at the break.
Brad England powered his way over the first try of the second half before the Broncos grabbed a consolation try through scrum half Joe Keyes.
However, normal service was resumed shortly afterwards when replacement James Samme proved too strong for the visitors defence. Walters then completed his brace as he finished off a break from the Rhinos as they showed composure on attack.
The scoring was wrapped up late on when prop Dan Grange was on hand to go over following some good play down the right from the Rhinos.
