Thomas Morton hit an unbeaten 123 as Wiltshire rounded off their Group One campaign with victory over Wales Minor Counties in the Unicorns Knockout Trophy.
A four-wicket win at Sambourne Road ensured Wiltshire head into their quarter-final against Norfolk with a 100 per cent record.
Opener Aneurin Donald hit 54 for the visitors, who totalled 231 for nine after being inserted, but it was not enough to force a first victory of the competition as Wiltshire reached the target with 17 balls to spare thanks mainly to Morton's heroics.

Adverse weather conditions meant that Group One's other game between Cornwall and Dorset was abandoned without a ball being bowled.
Norfolk secured their last-eight spot with a tense two-wicket win over Hertfordshire, whose own qualification hopes were ended.
James Southgate and Benjamin Frazer hit fifties as Hertfordshire posted 223 for nine, but Norfolk chased it down with five balls to spare.
James Spelman contributed 84 while Ben France hit a half-century, before Ashley Watson and Chris Brown saw the visitors to victory in Harpenden.
Elsewhere in Group Two, Bedfordshire won their first game of the campaign by four wickets away at Cambridgeshire.
Lewis Bruce top-scored with 44 for the hosts, who recorded 188 for nine.
But a 79 from Luke Thomas and George Thurstance's 68 set up the visitors' chase, which was completed by Shabhaz Hussain's 11 from just four balls and J Carpenter, who had earlier taken 3-41 with the ball.
The weather helped Cheshire and Cumberland secured the top two spots in Group Three.

Cheshire finished first after their clash with Lincolnshire lasted just 16 balls, with the visitors eight for one after Akhil Patel has been ousted by Adam Syddall.
Four overs were possible in Cumberland's showdown with Shropshire at Cockermouth before play was abandoned, with the hosts on 12 without loss.
Cheshire's last-eight opponents will be Herefordshire , who beat Berkshire by eight wickets.
David Ball took 4-25 as Berkshire were skittled out for just 92 and, despite Liam Gwynne and Nitesh Patel both perishing in to opening eight deliveries of the response, Bradley Wadlan and Charlie Walker safely steered their side home.
In Group Four's other game, Staffordshire against Buckinghamshire was abandoned without a ball being bowled.
