Holds, catching batsman, showing guts (12)
I believe the answer is:
chitterlings
'guts' is the definition.
(I've seen this before)
'holds catching batsman' is the wordplay.
'holds' becomes 'clings' (I am not sure about this - if you are sure you should believe this answer much more).
'catching' means one lot of letters goes inside another.
'batsman' becomes 'hitter' (synonyms).
'clings' enclosing 'hitter' is 'CHITTERLINGS'.
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for chitterlings that I've seen before include "guts" , "The smaller intestines of a pig, cooked as food" .)
