Yours truly during game had fruit (6)
I believe the answer is:
pomelo
'fruit' is the definition.
(pomelo is a kind of fruit)
'yours truly during game' is the wordplay.
'yours truly' becomes 'me'.
'during' means one lot of letters goes inside another.
'game' becomes 'polo' (polo is a kind of game).
'me' inserted into 'polo' is 'POMELO'.
'had' is the link.
(Other definitions for pomelo that I've seen before include "Largest citrus fruit" , "Shaddock" .)
