Slugger Aaron (4)
I believe the answer is:
hank
'slugger aaron' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hank that I've seen before include "Coil of wool for American Henry" , "Loop of yarn" , "-- Marvin, guitarist" , "Skein (of wool, hair)" , "Henry - coil of rope, wool or yarn" .)
