Served past (4)
I believe the answer is:
aced
'served past' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aced that I've seen before include "passed with highest marks in US" , "Sailed through" , "Comprehensively beaten" , "Reached a golf hole in one shot" , "got a hole in one" .)
