They use baseball bats regularly in set way: Ron Kray angrily smashed knees (3,4,7)
I believe the answer is:
new york yankees
'they use baseball bats regularly in set' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'way ron kray angrily smashed knees' is the wordplay.
I cannot really understand how this works, but
'way' could be 'w' (Compass direction - West) and 'w' is found in the answer.
an anagram of 'kray' is 'rkya' which is present in the answer.
an anagram of 'knees' is 'nkees' which is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for new york yankees that I've seen is " nine of diamonds?".)
