Run under superb service tree (4)
I believe the answer is:
acer
'tree' is the definition.
(I've seen this before)
'run under superb service' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'under' says to put letters next to each other.
'superb service' becomes 'ace' (ace is a tennis serve).
'r' after 'ace' is 'ACER'.
(Other definitions for acer that I've seen before include "ornamental tree" , "Tree with winged fruit" , "Tree of maple family" , "Plant" , "Tree or shrub of the maple genus" .)
