Game scores adjusted, City at the top (8)
I believe the answer is:
lacrosse
'game' is the definition.
(lacrosse is a kind of game)
'scores adjusted city at the top' is the wordplay.
'adjusted' is an anagram indicator.
'city' becomes 'la' (Los Angeles).
'at the top' means one lot of letters go next to another.
'scores' anagrammed gives 'crosse'.
'crosse' put after 'la' is 'LACROSSE'.
(Other definitions for lacrosse that I've seen before include "Ball game using netted stick" , "Game played with netted sticks" , "Game played with a netted stick" , "Like thirteen of the other clues in the French" , "Game played with nets on sticks" .)
