hogtie

'hamper' is the definition.
Although both the answer and definition are verbs in their base form, I cannot see how one could define the other.

'greedy person at cup match' is the wordplay.
'greedy person' becomes 'hog' (informal term).
'at' is a charade indicator (letters next to each other).
'cup match' becomes 'tie'.
'hog'+'tie'='HOGTIE'

'producing' acts as a link.
