Winning the toss and electing to bat, the Flintshire side were dismissed for 158, Elliot Colclough (50) and Peet Pienaar (39) putting on 78 for the first wicket before the rest of the batting collapsed.

Denbigh collapsed to 74 all out in response, Venumadhav Peram 3-14 off 7.4 and Cai Pearson 2-16 for the winning hosts, who turned over high-flyers Northop seven days earlier.
Nathanael Scott led the charge with 96 as Saints set a mighty total of 243-8 after winning the toss and deciding to bat.
