Featherstone Rovers recovered from 10-4 down at half-time to win 24-10 at Workington Town in Sunday’s Championship Shield game.
Featherstone’s third successive victory strengthened their hold on top spot.
Their closest rivals Dewsbury Rams and and London Broncos suffered home defeats against Whitehaven and Hunslet Hawks respectively.
Rovers are now third points ahead of second-placed Dewsbury and six ahead of third-placed London.

Featherstone’s only first-half points came from Alex Foster’s 12th minute try.
Rovers turned the game round with a dominant second-half display, scoring 20 unanswered points with tries from Will Sharp, Steve Snitch and Will Milner, plus four goals by Paul Sykes.
