Champ, looking leaner, secures two points (3,6)

I believe the answer is:

the winner

'champ' is the definition.
(the champion)

'looking leaner secures two points' is the wordplay.
'looking leaner' becomes 'thinner' (looking more lean).
'secures' means one lot of letters goes inside another.
'two points' becomes 'ew' (east and west).
'thinner' going around 'ew' is 'THE WINNER'.
