Baltimore ballplayer (6)
I believe the answer is:
oriole
'baltimore ballplayer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oriole that I've seen before include "(Tropical or American) songbird" , "Bird, Baltimore --" , "Songbird with yellow and black plumage -- Leo or I (anag)" , "Oil ore, strangely, for the songbird" , "Bright-plumaged bird" .)
