Inform then woo a sporting arena (5,5)

Ross

I believe the answer is:

grass court

I'm a little stuck... Click here to teach me more about this clue!

'a sporting arena' is the definition.
The definition suggests a singular noun which matches the answer.

'inform then woo' is the wordplay.
'inform' becomes 'grass'.
'then' means one lot of letters go next to another.
'woo' becomes 'court' (synonyms).
'grass'+'court'='GRASS COURT'

Can you help me to learn more?

(Other definitions for grass court that I've seen before include "feature of Wimbledon?" , "Such as used at Wimbledon" , "what one found at Wimbledon" .)

I've seen this clue in the Sydney Morning Herald.
