Batting gets worse, and run out is a disaster (4,4)

'worse and run out is a disaster' is the definition.
I can't tell whether this defines the answer.

'batting gets' is the wordplay.
I cannot really understand how this works, but
'gets' could be 'goes' ('go' can be a synonym of 'get') and 'goes' is found within the answer.
The remaining letters 'west' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
