Love Mark’s statuette (5)
I believe the answer is:
oscar
'statuette' is the definition.
(the golden Oscar statuette)
'love mark's' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'mark' becomes 'scar' (mark left by an injury).
'o'+'scar'='OSCAR'
(Other definitions for oscar that I've seen before include "Comms code for "O"" , "to wit involved in row" , "-- Wilde, author" , "Statuette awarded by Hollywood Academy" , "academy's prize" .)
