Star players getting nothing right (6)
I believe the answer is:
castor
'star' is the definition.
(Castor is an example)
'players getting nothing right' is the wordplay.
'players' becomes 'cast' (I've seen this before).
'getting' means one lot of letters go next to another.
'nothing' becomes 'o' (looks like zero - 0).
'right' becomes 'r' (common abbreviation).
'cast'+'o'+'r'='CASTOR'
(Other definitions for castor that I've seen before include "hat" , "Sprinkler" , "for wheel? Yes and no" , "Brother to Pollux" , "Pollux's twin" .)
