Baseball great Duke or rock singer Dee (6)

I believe the answer is:

snider

I believe this is a double definition.

'baseball great duke' is the first definition.
(I've seen this in another clue)

'rock singer dee' is the second definition.
(I've seen this in another clue)

(Another definition for snider that I've seen is " More sneering".)

I've seen this clue in the Newsday.
