Central character in Wimbledon can have a wild fall (9)

I believe the answer is:

avalanche

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

'fall' is the definition.
(I know that avalanche is a more specific form of the action fall)

'central character in wimbledon can have a wild' is the wordplay.
'central' becomes 'a' (I can't explain this - if you can you should give a lot more credence to this answer).
'character in' says to take the centre (I've seen 'characters in' mean this).
'a wild' indicates anagramming the letters.
The centre of 'wimbledon' is 'l'.
'l'+'can'+'have'='lcanhave'
'lcanhave' anagrammed gives 'valanche'.
'a'+'valanche'='AVALANCHE'

Can you help me to learn more?

(Other definitions for avalanche that I've seen before include "Big snowfall" , "Landfall" , "Disastrous snowfall" , "heavy snowfall" , "Come down heavily" .)

I've seen this clue in The Telegraph.
