After match, embarrassed to be in rows (6)
I believe the answer is:
tiered
'be in rows' is the definition.
(I've seen this before)
'after match embarrassed' is the wordplay.
'after' says to put letters next to each other.
'match' becomes 'tie' (I've seen this before).
'embarrassed' becomes 'red' (I've seen this before).
'tie' put next to 'red' is 'TIERED'.
'to' acts as a link.
(Other definitions for tiered that I've seen before include "Constructed in layers, like wedding cake" , "In ranks" , "Arranged in levels" , "Arranged in rising 5 ac" , "Laid out in layers, like wedding cake" .)
