Reportedly, team sounded exasperated (6)
I believe the answer is:
sighed
'sounded exasperated' is the definition.
(a sigh is a sound made in exasperation)
'reportedly team' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'team' becomes 'side' (both can mean a sports team).
'side' sounds like 'SIGHED'.
(Other definitions for sighed that I've seen before include "expressed resignation, say" , "Expressed dejection" , "Breathed deeply and heavily" , "Exhaled softly and sadly" , "Moaned" .)
