Performer raced off, baton finally collected (6)
I believe the answer is:
dancer
'performer' is the definition.
(I know that dancer is a type of performer)
'raced off baton finally collected' is the wordplay.
'off' indicates an anagram.
'finally' indicates one should take the final letters.
'collected' indicates putting letters inside (inserted letters are collected by others).
The last letter of 'baton' is 'n'.
'raced' with letters rearranged gives 'dacer'.
'dacer' going around 'n' is 'DANCER'.
(Other definitions for dancer that I've seen before include "''I hope you have the feet of a ...'' (Charlie McGettigan)" , "One of Santa's reindeer" , "One in the same team as, say, Rudolf" , "Ballerina or chorus girl?" , "Terpsichorean" .)
