Tigers hooker Scott Moore was sin-binned after just two minutes for a late challenge on Kevin Sinfield and Rhinos scored two tries while he was off, Ashley Gibson and Rob Burrow going over, Sinfield converting the first.

Richard Owen pulled a try back for Cas, converted by Kirk Dixon, but three tries in six minutes saw Leeds take total control, Lee Smith, Carl Ablett and Ali Lauitiiti going over and Sinfield adding another goal to make it 24-6 at the break.

Jordan Tansey touched down Burrow's kick at the start of the second-half to end Tigers' hopes of a comeback and Brent Webb went over on the hour, with two Sinfield goals making it 36-6.

Luke Dorn pulled a try back for Tigers, Dixon again adding the extras, but Leeds finished strongly, Tansey completing his hat-trick and Danny McGuire also crossing in the final 10 minutes.

Sinfield kicked two more goals and Gareth Ellis booted the final conversion on what could be his last appearance at Headingley Carnegie.
