Game time for a Saint (7)
I believe the answer is:
bridget
'a saint' is the definition.
(I've seen this before)
'game time' is the wordplay.
'game' becomes 'bridge' (bridge is a kind of game).
'time' becomes 't'.
'bridge'+'t'='BRIDGET'
'for' is the link.
(Other definitions for bridget that I've seen before include "Miss Jones the diarist" , "Saintly woman" , "Saint" , "Girl" .)
