Hope-Bell, Edwards and Wallace made first team debuts, as did batter Callum Nicholls, 22, and Australian paceman Connor O’Riordan, whose bid to develop in Wales after missing out in New South Wales echoes the example of county stalwart Timm van der Gugten.

Wicket-keeper Alex Horton, 22, was the top run scorer.

Nicholls and Hope-Bell played major roles in the dramatic closing win over Worcestershire, with Pontarddulais product Edwards marking his potential by taking three wickets after being thrust into the squad because of injuries.

“Of the younger lads, Jack Hope-Bell has been impressive throughout the tournament and showed again [against Worcestershire] he’s got a future here,” said Harrison.

“Callum Nicholls has had a couple of scores and to get 70 in a chase was really good. There’s a lot of experience for some of the younger players and it’s shown we’ve got a bright future ahead.”

Glamorgan are far from unique in blooding youngsters in the One Day Cup while some of their star names are away at the Hundred franchise tournament, but the perennial ambition to have a Welsh core to the team looks closer to fulfilment than has been the case since the noughties.

As well as those used, 18-year-old seam bowler Tom Norton – a breakout star of recent Championship games – missed the competition because of a back problem which will probably keep him out for the season, while batter Jacob Blades recently played for England under-19s at the age of 17.

“You’ve always got to plan for the future and this competition gave us that opportunity to develop a few of our players, playing against Ben Stokes for Durham is a great experience when they’ve watched him on TV playing for England.”

Captain Andy Gorvin, the oldest player at 29 for several matches, was compared to a school-teacher in charge of the youngsters by one opposition commentator.

“My family did tell me about that! I try to help in whatever way I can and when it doesn’t go right, it’s how to keep the guys going,” said Gorvin.

“The most important thing about sport is having the resilience to come back the next day. They’ve always tried to improve, it’s a three-week block with eight games so you improve on the job and I’ve tried to guide as well as I can, and I’ve got to improve as well.”
