Leeds put Widnes to the sword with a 12-try show to warm-up emphatically for the Challenge Cup final at the end of the month.
The Vikings were never really had a look in as the home side raced in to an 18-0 lead within 13 minutes, and despite moments of resolve from the visitors, the Rhinos were too strong.
Widnes hit back with a well taken try of their own through Stefan Marsh, but by the time Frank Winterstein added their second try, the Rhinos had added three more through Zak Hardaker, Richard Moore and Hall.
Brett Delaney‘s converted try on the hooter put Leeds 40-12 to the good at half time, and probably left coach Brian McDermott pondering how best to protect his players ahead of their Wembley date against Warrington.
They kept pressing and forced consecutive drop-outs, before a masterful drop kick by Sinfield from under his own posts relieved the pressure and broke Widnes’ momentum.
The final quarter turned in to a procession for the home side, as they ran in tries through Kylie Leuluai, Stevie Ward and another from Hardaker, before young forward Jimmy Kleinhorst grabbed his first senior try on the hooter to the round scoring off to 68-24.
