Speaker's greeting top athlete (4,6)

I believe the answer is:

high jumper

'athlete' is the definition.
(I've seen this before)

'speaker's greeting top' is the wordplay.
'speaker's' shows a homophone (sound like).
'greeting' becomes 'hi' (hi is a kind of greeting).
'top' becomes 'jumper' (type of garment worn as a top).
'hi' sounds like 'high'.
'high'+'jumper'='HIGH-JUMPER'

(Another definition for high jumper that I've seen is " athlete".)

I've seen this clue in The Telegraph.
