Yorkshire’s S9 Terriers side are through to the regional final next month.
Alistair Domville’s troops had already qualified for the Northern final before Sunday’s trip to North Wales, where they were victorious with only eight players available due to injury and unavailability.
A 30-run win over the Wales Disability team ensured top spot in the table ahead of their opponents, who they will meet again at Treeton CC on August 21.
The unbeaten Terriers’ completed group stage saw them win five of six matches and finish with 160 points – more than any other team across the four regions involved at S9.
On Sunday, the Terriers posted 179-3 from 30 overs, centred around 50 apiece for opener Richard Lovedale and number three Luke Messenger. They both retired out.
Jamie Dillon also contributed a quick-fire an unbeaten 36 from number four.
In reply, Wales, also short on players themselves, finished on 159-8 in 28.4 overs, Oliver Fawcett impressing with 3-25 from five, with all of his wickets bowled. Opener Ian Hughes was a lone hand with 70 retired not out for the hosts.
Captain Domville added two wickets to put the icing on the cake of a superb group campaign.
Now, the next aim will be silverware.
