Excellent batches oddly abandoned (3)
I believe the answer is:
ace
'excellent' is the definition.
(ace can informally mean very good)
'batches oddly abandoned' is the wordplay.
'oddly abandoned' means one should take alternating letters (letters in odd-numbered positions removed).
The alternating letters of 'batches' are 'ACE'.
(Other definitions for ace that I've seen before include "unit > of highest quality" , "SERVE?] that's non-returnable" , "Winning serve; hole in one" , "Best type of tennis serve" , "star" .)
