Go berserk in high-scoring Lord’s game? (3,4)
I believe the answer is:
run riot
'go berserk' is the definition.
(I've seen this before)
'high-scoring lord's game?' is the wordplay.
I cannot really understand how this works, but
'game?' could be 'ru' (rugby union) and 'ru' is present in the answer.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for run riot that I've seen before include "Behave unrestrainedly" , "Act wildly" , "Grow profusely (of plants)" , "Raise hell" , "Behave wildly and without restraint" .)
