Delivery extra far out (4)
I believe the answer is:
wide
This clue is a triple definition!
'delivery extra' is the first definition.
'wide' can be an answer for 'extra' (cricket term). I'm unsure of the 'delivery' bit.
'far' is the second definition.
('wide' can be a synonym of 'far')
'out' is the third definition.

Can you help me to learn more?
(Other definitions for wide that I've seen before include "lax in morals" , "Far from the target" , "Spacious; an extra" , "Gaping" , "Far from the mark" .)
