It is a vulnerability not unknown to their seniors: Warwickshire were let down by their foursomes play against Yorkshire in the English Boys County Finals at Little Aston yesterday.
And on the strength - or lack of strength - of their pairs play, they went down to an anti-climactic 51/2-31/2 defeat.
Over the years, and at all levels, Warwickshire have produced outstanding individuals; they still do and they actually beat Yorkshire in the singles yesterday.
Andy Sullivan, their captain, having won a maximum two points against Gloucestershire on the first day, breezed through his singles again.
But in partnership with Andy Evans he went down in the top foursomes. The first of three defeats out of three. Jack Sant and Evans were Warwickshire's other singles winners. Essex, whom Warwickshire play today, are now the favourites to win this round robin competition.
They beat Gloucestershire by two points yesterday are are now a clear point ahead of Warwickshire and Yorkshire.
But Warwickshire still have a great deal to play for today - if they can get their pairs working. Yorkshire, who face the lame ducks, Gloucestershire, are also clinging on to their hopes.
