Nick Henry, winger (4-4)
I believe the answer is:
half-inch
'nick' is the definition.
(I've seen this before)
'henry winger' is the wordplay.
'henry' becomes 'hal' (short for Henry).
'winger' becomes 'finch' (finch is a kind of bird).
'hal'+'finch'='HALF-INCH'
(Other definitions for half-inch that I've seen before include "Small distance - steal!" , "Steal - about 1.27cm" , "Short distance - steal!" , "Steal (rhyming slang)" , "Steal (slang) - short length" .)
