JUNIOR George Heartfield has helped Cullingworth back on top of the Foster's Halifax League Second Division following their 120-run crushing of struggling Shelf.
His 104 was the backbone of the newcomers' 279-9, and he added 55 for the fourth wicket with Adie Powis (26) and 132 with Anthony Partington (69) for the sixth.
Shelf made little impact as they fell away to 159, Stuart Boardall making 35 while Dave Robinson claimed 5-34, Ali Ahmed 2-25 and Phil Poole jnr 2-45.
Denholme Clough moved into third place following their 211-run demolition of Old Town.
Imran Aslam (70) and Mohammed Yousaf (51) were the main run-makers in Clough’s imposing 322-8. Old Town's reply was weak and they finished on 111.
Clough's second team won by three wickets – but thought they had lost it when they were 99-6 chasing Old Town's 174.
Opener Alan Parkinson made 36 but it was Adam Quirie who took the game away from the visitors.
He blasted seven sixes and 11 fours in an unbeaten 112 as Clough reached their target in only 24 overs.
Naz Ahmed (3-28), Neil Armitage (3-41) and Darren Mead (3-51) had earlier shared the Old Town wickets as they recovered from 100-6.
