Delivery bowled Hampshire's opener, having pinched one run over point at last (5)
I believe the answer is:
birth
'delivery' is the definition.
(thesaurus)
'bowled hampshire's opener having pinched one run over point at last' is the wordplay.
'opener' says to take the initial letters.
'having pinched' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'run over' becomes 'r' (cricket abbreviation. I am not sure about the 'over' bit.**).
'at last' suggests the final letters.
The first letters of 'bowled hampshire' is 'bh'.
The last letter of 'point' is 't'.
'i'+'r'+'t'='irt'
'bh' enclosing 'irt' is 'BIRTH'.
(Other definitions for birth that I've seen before include "Beginning; ancestry" , "Nascence" , "origin" , "Beginning (of something)" , "Nacence" .)
