Salesbury went down to a Preston White-inspired Euxton at Ribchester Road on Saturday.
The overseas amateur took 8-37 as the Red Caps were dismissed for 122, and then hit 57 in reply to see the Chorley outfit to a seven-wicket win.
Salesbury went from 13 without loss to 23-4, before Joe Rawlinson and Peter Blackman (14) put on 41 for the fifth wicket.
But when Rawlinson was bowled by White for a 61-ball 28, wickets tumbled again.
Zeshan Shauket (31) and Mohamed Shabaz (24 not out) added 43 for the eighth wicket to take the score to 122, before White mopped up the tail.
White’s haul came off 18.2 overs.
Euxton opener Sam Tolley batted his side home in reply with an unbeaten 33.
He lost Nick Dunn for one, and Oliver Marsden without score - both to Shauket, but White (57) and Tolley put on 86, before the former fell after 10 fours and a six.
Captain Mark Winrow finished unbeaten on nine to seal victory.
On Saturday, Salesbury are at home to second place Great Harwood.
