Lob aloft poorly in game (8)
I believe the answer is:
football
'game' is the definition.
(I know that football is a type of ball game)
'lob aloft poorly' is the wordplay.
'poorly' is an anagram indicator.
'lob'+'aloft'='lobaloft'
'lobaloft' anagrammed gives 'FOOTBALL'.
'in' acts as a link.
(Other definitions for football that I've seen before include "Lob aloft (anag)" , "Gambling on soccer results" , "The beautiful game, some say" , "See 20" , "Loft a lob badly in this game" .)
