In a row, angry, after inconclusive result (6)
I believe the answer is:
tiered
'in a row' is the definition.
(laid out in rows)
'angry after inconclusive result' is the wordplay.
'angry' becomes 'red' (someone may go red when angry).
'after' is a charade indicator (letters next to each other).
'inconclusive result' becomes 'tie' (a sports match with no winner).
'red' put after 'tie' is 'TIERED'.
(Other definitions for tiered that I've seen before include "Constructed in layers, like wedding cake" , "Cunstructed in layers" , "Set out in layers like wedding cake" , "Arranged in levels" , "Ranked" .)
