'win by a rugby score in the cold season' is the definition.
I can't judge whether this defines the answer.

'win by a rugby score in' is the wordplay.
'win' becomes 'w' (abbreviation in sport).
'by' says to put letters next to each other.
'a rugby score' becomes 'try' (I've seen this before).
'try' after 'in' is 'intry'.
'w'+'intry'='WINTRY'

Can you help me to learn more?
