KEIGHLEY Cougars' final travels of the season brought with it an eighth defeat in 11 away games as Doncaster emerged 48-12 victors, mainly through the brilliance of Rangi Chase.

The home side opened the scoring when Tom Halliday touched down in the corner but only after superb individual work from Chase to unlock the Keighley defence and weave his way through to create the opportunity.

Chase also proved the provider for the Dons' second, his quick ball from dummy half being collected and forced home between the sticks by the onrushing Brad Foster.

Keighley were on the back foot and shot themselves in that foot from the restart, conceding a penalty that allowed Doncaster to gain 60 metres and send Jason Tali through a bus-sized gap to touch down with considerable ease.

Halliday then thought he had his second courtesy of superb link-up play between Chase and former Cougar Matty Beharrell, but the referee ruled the effort out for a forward pass in the build-up.

The game was quickly turning into the Rangi Chase show and the former Super League Man of Steel produced an outrageous moment of magic to extend his side's lead further.

After picking up a loose ball, Chase provided a sensational no-look offload around his back to the supporting Halliday who then raced 70 metres to the corner to this time seal his brace.

The Cougars got off to a nightmare start to the second half, spilling the ball 10 metres out from their own line, allowing Connor Bower to send the ball to Watson Boas who dived over from close range.

The healthy travelling support from Keighley then were finally given something to shout about, a big hit from Kieran Moran forcing a knock on from Beharrell and Billy Gaylor took advantage to race over from 40 metres out.

However, despite a brief spell on top following the try, Doncaster then turned the screw once more as a break from Halliday put them on the front foot and the winger would complete his hat-trick on the back of super link-up play between Chase and Jordan Howden.

The Cougars grabbed a second courtesy of two former Dons players, Jack Miller’s grubber bouncing through and being touched down by Jason Muranka.

But the visitors were then themselves outdone by a grubber with Ryan Boyle pouncing on a short kick through the defensive line by Kyle Kesik.

The home side weren’t finished there with Sam Doherty scoring after taking a pass out of the scrum and turning through a tackle to force his way over from close range.

And they still found time for one more score after the Cougars failed to gain possession from a short kick-off and Connor Bower broke a tackle to stroll home in the corner.
