Baseball's ____ Williams (3)
I believe the answer is:
ted
'baseball's williams' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ted that I've seen before include ". . . Kennedy, Father . . ." , "Comic TV Father" , "Heath or Danson?" , "TV comedy series 'Father . . . '" , "Hang out to dry" .)
