Reveals the record is beaten (9)
I believe the answer is:
discloses
'reveals' is the definition.
(disclosing is a kind of revealing)
'the record is beaten' is the wordplay.
'the record' becomes 'disc' (synonyms).
'is beaten' becomes 'loses' (I can't justify this - if you can you should give a lot more credence to this answer).
'disc'+'loses'='DISCLOSES'
Can you help me to learn more?
(Other definitions for discloses that I've seen before include "leaks" , "Gives info" .)
