Guy’s husband wearing baseball attire (4)

I believe the answer is:
chap
'guy's' is the definition.
(both can mean a man)
'husband wearing baseball attire' is the wordplay.
'husband' becomes 'h' (abbreviation).
'wearing' means one lot of letters goes inside another.
'baseball attire' becomes 'cap' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'h' put inside 'cap' is 'CHAP'.
Can you help me to learn more?
(Other definitions for chap that I've seen before include "Fellow; sore skin area" , "Fellow < makes > crack" , "Raw, cracked patch on skin" , "Fish" , "Become raw from cold - fellow" .)
