Rushed the starting price to the editor (4)
I believe the answer is:
sped
'rushed' is the definition.
('speed' can be a synonym of 'rush')
'starting price to the editor' is the wordplay.
'starting price' becomes 'sp' (abbreviation in betting).
'to the editor' becomes 'ed' (abbreviation).
'sp'+'ed'='SPED'
'the' is the link.
(Other definitions for sped that I've seen before include "Went fast" , "Made haste" , "was 8 [FLEET]" , "Travelled quickly" , "got a move on" .)
