Sampras of the court (4)
I believe the answer is:
pete
'sampras of the court' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pete that I've seen before include "- Seeger, US folk singer" , "For his sake" , "-- Sampras, tennis ace" , "Small 14 [PETER JONES]" , "- Sampras, tennis star" .)
