A pretender of promise and a seasoned old-stager.
A batter of international calibre, and an all-rounder seeking to make his mark.
Diametrically opposed they may be, but the stories of Archie Vaughan and Colin Ingram each showcase, in their own way, the beauty of the One Day Cup.

Vaughan - son of Ashes-winning England captain Michael - earned his maiden senior appearance in this year's 50-over competition.
And his control was immediately impressive - with the 18-year-old maintaining an economy rate of 4.20 across six white-ball appearances.
If three wickets across those six matches appeared to be a modest return, Vaughan was just getting comfortable on the senior stage.
And that groundwork is already paying off in spades. Soon after, in a crunch County Championship clash with leaders and defending champions Surrey, Vaughan belied his inexperience to take eleven wickets in the match.
Vaughan's exploits helped to seal victory for Somerset and catapult his side back into the title race. After performing under such pressure, the List A showpiece could prove to be another breakthrough moment for a player of some promise.
Sometimes, however, there is no substitute for experience.
Now 39 years young, Colin Ingram has graced the global stage with South Africa, earned a reputation as a big hitter on the franchise circuit and become embedded in the fabric of Glamorgan's limited-overs sides.
Supporters in this parish need no reminding of his quality, after his unbeaten 103 saw Glamorgan to victory over Notts at Neath in July.
And since returning to the red-ball format, the left-hander has been no less impressive, racking up an unbeaten 257 against Leicestershire at Cardiff.
Darren Stevens' heroics in the 2021 One Day Cup Final showed that nous and knowhow can be critical in times of tension.
Ingram will be hoping that his experience trumps the exuberance of youth at Trent Bridge this year.
