Baltimore athlete (6)
I believe the answer is:
oriole
'baltimore athlete' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oriole that I've seen before include "(Tropical or American) songbird" , "Bright songbird" , "Oil ore, strangely, for the songbird" , "Black and yellow US bird" , "Bird, Baltimore --" .)
