Comes through, in adversity - takes balls (4,4)

I believe the answer is:

gets over

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

'adversity takes balls' is the definition.
I can't judge whether this definition defines the answer.

'comes through' is the wordplay.
'comes' becomes 'gets' ('get' can be a synonym of 'come').
'through' becomes 'over' (I've seen this in other clues).
'gets'+'over'='GETS OVER'

'in' acts as a link.

Can you help me to learn more?

I've seen this clue in The Independent.
