Balls bowled at pens close to farmhouse to get pig out (7)
I believe the answer is:
overeat
'pig out' is the definition.
(synonyms)
'balls bowled at pens close to farmhouse' is the wordplay.
'balls bowled' becomes 'over' (sequence of six balls bowled in cricket).
'pens' indicates putting letters inside (inserted letters are held or penned in).
'close to' suggests the final letters (the close of something is the end).
The final letter of 'farmhouse' is 'e'.
'over'+'at'='overat'
'overat' placed around 'e' is 'OVEREAT'.
'to get' is the link.
(Other definitions for overeat that I've seen before include "Gobble to excess" , "pig out?" , "ignore threat of a big corporation?" , "Binge" , "Consume too much food, stuff your stomach" .)
