Tennis star Chris (5)
I believe the answer is:
evert
'tennis star chris' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for evert that I've seen before include "arrange to have the wrong side out?" , "Turn inside out (biol.)" , "Chris --, female tennis star" , "Chris - - (women's tennis)" , "Tennis champion" .)
