Some hate amateurish group of players (4)
I believe the answer is:
team
'group of players' is the definition.
(I've seen this in another clue)
'some hate amateurish' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'TEAM' is hidden within 'hate amateurish'.
(Other definitions for team that I've seen before include "Mate with game group" , "Competitive side" , "(Two or more) horses in harness" , "Squad; side" , "Mate for a group of players" .)
