Turn inside out (5)
I believe the answer is:
evert
'turn inside out' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for evert that I've seen before include "Hitter of 6 [TENNIS BALL]" , "Tennis champion" , "Former US World No 1 tennis player, b. 1954" , "Turn inside out (biol.)" , "Chris - - (women's tennis)" .)
