Land an uppercut, good making connection (8)

'land an uppercut good making connection' is the definition.
I can't tell whether this defines the answer.

'good making connection' is the wordplay.
I cannot really see how this works, but
'good' could be 'g' (abbreviation) and 'g' is present in the answer.
'connection' could be 'hitch' (hitch is a kind of connection) and 'hitch' is found within the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
