Runs guest out to falls (7)
I believe the answer is:
'runs guest out to falls' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'runs guest out to falls' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'out' indicates an anagram (out can mean wrong or inaccurate).
'to falls' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'rguest' is an anagram of 'gutser'.
Can you help me to learn more?
