Where we may see seeds winning (2,1,4)
I believe the answer is:
on a roll
'winning' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for on a roll that I've seen before include "Piano music was once stored here" , "Where one lists people" , "Where ham may be" , "spread may be smeared thus" , "How butter may be spread" .)
