Big shot getting bowled out in haste (8)
I believe the answer is:
celerity
'haste' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for celerity that I've seen before include "Pace" , "Haste" , "Dispatch" , "Swiftness of movement" , "Quickness" .)
