Bowl over with star catching last from mid-wicket (4)
I believe the answer is:
stun
'bowl over' is the definition.
(I've seen this before)
'star catching last from mid-wicket' is the wordplay.
'star' becomes 'sun' (the Sun is a star).
'catching' is an insertion indicator.
'last from mid wicket' becomes 't' (I can't justify this - if you can you should believe this answer much more).
'sun' enclosing 't' is 'STUN'.
'with' is the link.
Can you help me to learn more?
(Other definitions for stun that I've seen before include "Daze with nuts" , "Daze, paralyse" , "Stagger, amaze" , "Take aback" , "Nuts (anag)" .)
