Creep, caught naked, left (5)
I believe the answer is:
crawl
'creep' is the definition.
('crawl' can be a synonym of 'creep')
'caught naked left' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'naked' becomes 'raw' (I've seen this before).
'left' becomes 'l' (common abbreviation).
'c'+'raw'+'l'='CRAWL'
(Other definitions for crawl that I've seen before include "This can take you quickly through water" , "Baby-like advance" , "be overrun" , "Go on all fours" , "swarm" .)
