Delivery from first of youthful employees unwrapped (6)
I believe the answer is:
yorker
'delivery' is the definition.
(type of cricket delivery)
'first of youthful employees unwrapped' is the wordplay.
'first of youthful' becomes 'y' (1st letter of 'youthful').
'employees' becomes 'workers' (I've seen this before).
'unwrapped' says to take the centre (the letters which wrap the word are removed).
The middle letters of 'workers' are 'orker'.
'y'+'orker'='YORKER'
'from' acts as a link.
(Other definitions for yorker that I've seen before include "Cricket delivery, pitching under the bat" , "Ball pitching just under bat (cricket)" , "Difficult cricket delivery to play" , "Delivery pitching directly under the bat" , "Bowler's stratagem (cricket)" .)
