Court star Steffi (4)
I believe the answer is:
graf
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">court star steffi</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for graf that I've seen before include "German count - German tennis player" , "Steffi --, tennis champion" , "German tennis player, b. 1969" , "Seven-times women's Wimbledon champion, b. 1969" , "Noted tennis player" .)
