Three-times Challenge Cup winners Featherstone Rovers booked their place in the fifth round with a seven-try victoory over Whitehaven in Cumbria.
Rovers, who won the competition in 1967, 1973 and 1983, were far too good for fellow Championship outfit Whitehaven at the Recreation Ground on Saturday evening.
The Cumbrians, boosted by their first league win of the season against London Broncos the previous weekend, were level at 12-12 late in the first half but Rovers ran away with the game in the second period to book their place in tomorrow’s fifth round draw.
Prop Andy Bostock, making his first start of the season, put Rovers ahead with a 10th minute try.
Whitehaven replied five minutes later when Papua New Guinea international Jessie Joe Parker, an ex-Rovers player, scored against his old club.
Featherstone full-back Will Sharp crossed but Whitehaven levelled again when Dion Aiye went over and John Paul Brocklebank kicked his second goal.
Rovers edged back in front shortly before half-time when Sharp darted in for his second and they completely dominated the second-half, adding 20 unanswered points.
Ben Blackmore, Will Milner and substitute Matt James got on the scoresheet before Nathan Chappell rounded things off with the final try five minutes from time.
Former Wakefield back Paul Sykes kicked three goals and French international Remy Marginet landed one for Featherstone.
