There is still no sign of January blues at Holden Road as Burnley continued their good start to the New Year, toppling second placed Heaton Moor on Saturday.
Both sides served up a physical and ultimately nail-biting encounter.
Burnley should have taken an early lead from a penalty, but the usually reliable Gus Ferguson missed.
Burnley continued their assault on the Moor line, and were held up on two occasions before the visitors cleared their lines.
Moor started to get into the game, and from an offside they kicked a penalty, then, after a well-worked move, they carved Burnley open, as their impressive centre scored out wide.
Burnley opened the second half in determined mood, and after prolonged pressure, Simon Finnan spotted a chink, and darted blind to put fly half Ferguson into space to dive over.
Things got better as Ferguson made up for his earlier miss with a superb long range effort to tie the scores.
Burnley kept attacking, and a great run by Richard Murray won a penalty, which they opted to run, and after several drives, skipper Luca Angelone burrowed over.
As the visitors got more desperate, Burnley’s defence became more frenzied, but Moor couldn’t find a way through, eventually spinning the ball wide, where their excellent outside centre made a great break before he was bundled into touch.
Shortly after the whistle went and Burnley had won 13-8.
The thirds went out of the cup 22-0 at Bolton. Mark Bertenshaw was man of the match
Tomorrow, Burnley are at Mossley Hill, the seconds host Vale of Lune and the thirds travel to Colne, all at 2-15 p.m.
