Focus attention on minor securing trophy (9)
I believe the answer is:
spotlight
'focus attention on' is the definition.
'minor securing trophy' is the wordplay.
'minor' becomes 'slight' (I've seen this before**).
'securing' indicates putting letters inside.
'trophy' becomes 'pot' (I've seen this before).
'slight' enclosing 'pot' is 'SPOTLIGHT'.
(Other definitions for spotlight that I've seen before include "Where attention is focused" , "Prominent position" , "Give prominence to" , "Stage actor may be in it" , "Direct attention to" .)
