The Championship trap-door continues to open ever wider for struggling Doncaster.
They now find themselves six points adrift at the foot of the table after slumping to a 13th league defeat in as many starts.
The visit of second-bottom Workington Town, who had lost 70-0 in their previous away game, was viewed by everyone connected with the club as a very winnable game.
It was certainly regarded as a ‘must-win’ game and that remained a distinct possibility at the break despite trailing 10-6.
But not for the first time this season – the team suffered a similar fate in the game at Workington back in March – they fell away badly in the second half and conceded five further tries without reply.
Equally depressing for coach Paul Cooke was the fact that his charges hardly ever got into the Town 20 let alone come close to a try.
The determination to both extract revenge for the 33-6 defeat at Derwent Park and finally get off the mark in 2015 was etched on the players’ faces from the first whistle.
But Town soon showed they also meant business.
The Dons opened the scoring on 13 minutes when full-back Dave Scott just managed to hold off the cover in a 25 metre race to the line after supporting a break by second-rower Steve Snitch. Scott also added the extras.
Town hit back strongly and the home defence did well to deny strong-running second-rower Jarrad Stock a try. Loose-forward Mike Emmett almost dummied his way into space close to the Town line but it was the Cumbrians who were the next to trouble the scoreboard operator with a try by Wigan centre Rhodri Lloyd.
Fellow Wigan prospect Lewis Tierney – the oldest son of former dual code international Jason Robinson - showed blistering pace to score a second Town try a couple of minutes later and with Jake Shorrock tagging on the extras, the Dons found themselves trailing 10-6.
Town missed out on the chance to extended their lead when Shorrock’s 50th minute penalty hit the post but the same player made no mistake from a similar range three minutes later.
Town added to their account with a well-worked try scored by Lloyd out wide.
Winger Tierney also bagged a second try after breaking the line 35 metres out and racing past Scott, no slouch himself, to score near enough for Shorrock convert to make it 22-6.
The game was embarrassingly one-sided at this stage and it came as no surprise when Tierney touched down in the corner to complete his hat-trick.
Doncaster were reduced to 12 men on 72 minutes, prop Mitch Clark being shown the red card for throwing a punch.
Town wasted no time in cashing in on their numerical advantage, second-rower Brett Phillips going over for a try converted by Kurt Horton.
Full-back Jack Murphy also went in a couple of minutes from time for Town’s last try with half-back Jamie Doran dropping a goal at the death to round off the scoring.
