DONCASTER turned the heat up on their Co-operative Championship One promotion rivals with a hard earned win in North Wales.
A strong second half display saw Tony Miller’s men bounce back from their heavy defeat at Workington and move them nine points clear of fifth placed Oldham at the half way stage of the campaign.
The top four teams will be promoted to the Championship when the regular league season comes to an end in September.
Paul Cooke, Craig Fawcett (2) and Mick Butterfield all went over after the break as the Dons moved up a gear despite the stifling heat at the Racecourse Ground in Wrexham.
The sides had gone in 18-18 at half time after a topsy-turvy first half which saw Russ Spiers cross twice for the visitors.
Chris Spurr also went over but the plucky hosts responded with tries from Simon Stephens, Billy Sheen and Andrew Moulsdale.
Rob Massam and Adam Clay touched down for the Crusaders in the second half but Doncaster, aided by six Tom Hodson conversions and a late Fawcett drop goal, returned to winning ways.
