Team supported by country lacking a finesse with the ball? (8)

I believe the answer is:

sidespin

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

'country lacking a finesse with the ball?' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'team supported' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'supported' becomes 'spin' (I can't justify this - if you can you should believe this answer much more).
'side'+'spin'='SIDESPIN'

'by' is the link.

Can you help me to learn more?

I've seen this clue in The Independent.
