THE Dons threw away the work of a blistering opening 15 minutes and slumped to a hefty defeat at the John Charles Sports Centre.
Hosts Hunslet hardly knew what hit them as the powerful Dons stormed out of the blocks.
But poor defending allowed the Hawks back into the game and gave them a platform for a relatively comfortable win.
It took five minutes for Doncaster to open the scoring. After gaining a new set from 20 metres, Matt Carbutt broke and Kyle Kesik capped the attack by forcing his way over.
Hunslet simply could not handle the sheer mass of Brett Waller in the early stages and he was involved in several powerful runs before forcing his way over on 10 minutes.
Bobbie Goulding added the conversion and also made sure of the extras three minutes later when Mark Castle again outlined the Dons’ forward dominance by surging over after good movement of the ball.
The Dons were in dreamland inside the first 15 minutes but the rest of the half proved nothing but a nightmare.
Suddenly forced onto the back foot, the Dons became static and flat-footed, allowing Hunslet to pick holes in their line.
The hosts pulled their first try back on 17 minutes when Liam Welham weaved his way through to score next to the posts with skipper Luke Helliwell converting.
Hunslet produced a sustained period of pressure in the aftermath and eventually found their way through with Liam Hood scoring.
They levelled on the half hour with Welham producing a peach of a pass to Paul Hughes giving him a clear run to the line, Helliwell converting.
Hunslet took the lead on 34 minutes when Keinhorst collected a misplaced pass and caught the Dons defence off guard to go over.
Helliwell converted and closed the half with a penalty kick. Doncaster started the second half strongly and won another set just five metres from the Hunslet line, laying the platform for Carl Hughes to reduce the deficit to two after Goudling’s conversion.
Two tries in five minutes midway through the secondhalf gave Hunslet an advantage they would not relinquish with second tries for Hood and Keinhorst before Helliwell edged Hunslet further clear with a pair of penalty kicks.
The hosts’ Stuart Kain coasted through with four minutes to go with Helliwell converting.
