Hanging Heaton’s Joe Fraser hit a maiden Bradford League century last Saturday but it wasn’t enough to prevent a derby defeat to Cleckheaton.
Heaton were reduced to 48-4 before Fraser led the recovery as he shared a 110-run fifth-wicket stand with David Stiff (52).
Fraser celebrated his maiden league century and ended 108 not out after hitting four sixes and 15 fours as the home side closed on 235-6.
Cleckheaton lost captain John Wood early on but opener Tim Jackson and overseas player Ammer Mahmood shared a superb 142-run second-wicket stand, which proved decisive.
Mahmood fell for 85 but Jackson steered Cleckheaton to a six-wicket win with an excellent 92.
East Bierley are second, a point behind new leaders Manningham Mills, following a 22-run victory over Lightcliffe in a match reduced to 27 overs a side.
Overseas paceman Waqas Maqsood produced a devastating spell of 7-31 as the last six Lightcliffe wickets fell for 12 runs as they went from 131-4 and through a dramatic collapse to 143 all out.
Bierley had earlier made 165-5 as Andrew Rennison hit five sixes and four fours in an innings of 71, while opener Tabbi Bhatti passed 5,000 Bradford League runs with his 34.
Champions Woodlands inflicted a first defeat of the season on previous leaders Pudsey Congs.
Openers Scott Richardson (92) and Sam Frankland (52) produced a superb 143-run stand, which set Woodlands on their way to posting 205-8.
Congs then struggled against the pace of overseas star Sarfraz Ahmed (4-24) and spinner Chris Brice (4-23) as they were bowled out for 115.
Victory saw Woodlands climb to third place.
