Female on farm runs for pitcher (4)
I believe the answer is:
ewer
'for pitcher' is the definition.
(synonyms)
'female on farm runs' is the wordplay.
'female on farm' becomes 'ewe' (female sheep).
'runs' becomes 'r' (cricket abbreviation).
'ewe'+'r'='EWER'
(Other definitions for ewer that I've seen before include "Large pitcher" , "Water-jar" , "Large water-jug" , "Container" , "Sort of jug" .)
