Nelson rebounded from their two defeats last week-end to record a highly satisfying victory over Church at Seedhiull on Sunday.
The visitors had the early advantage as they won the toss, elected to bat, and put on 22 without loss inside the first 7 overs.
It all went pear-shaped for them then as Sam Halstead clean bowled Levi Wolfenden for 15, professional Usman Tariq for nine and Harvey Aspin for a duck.
Richard Meade followed up by taking the wickets of Craig Fergusson (caught behind for 0) and Adam Greenwood (caught in the covers for 0) and Church were suddenly 32-5.
Lancashire League legend Joe Scuderi, making a welcome return to the Nelson line-up, snapped up a catch in the slips to dismiss Sam Holt, giving Meade his third victim.
Lloyd Aspin, however, batted superbly and kept the Nelson attack at bay as he recorded an excellent half-century.
He shared a 51-run stand with Andrew Bentley but, after Toxy Hussain had Bentley caught behind for seven, Neil Thompson (2-11) and Hussain (2-24) polished off the tail.
Aspin hit eight fours in is innings of 64 before Thompson bowled him. The Church innings ended on 114 in the 34th over.
Nelson opened their reply with Tyler McGladdery and professional Ryan Canning again, but disaster soon struck once more.
McGladdery was given out lbw for a duck in the first over, Canning lbw for one in the third and Lewis Bradley caught behind for four in the fourth. Toxy Hussain and Neil Thompson partially rescued the situation with a partnership of 35, but Hussain was brilliantly caught at point for 10.
Russell Bradley swiftly followed, caught at backward square-leg for none, putting Nelson on 47-5.
Harrison Phelan joined his skipper and they completed the recovery with a stand of 60 in 20 overs.
Phelan hit three fours as he passed his previous best score of 18 to record 27 valuable runs.
Nelson were still eight runs short of victory when Phelan was out, caught behind, but Scuderi finished the job, stroking seven runs, including one majestic boundary, from six balls faced.
Thompson had played a real captain’s innings as he faced 79 deliveries, hit five fours and was undefeated on 35 at the end.
Nelson are without a fixture tomorrow but travel to Burnley on Sunday for the first derby day of the season.
