A hint to start the ball rolling (3)

Ross

I believe the answer is:

cue

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

I cannot understand how the remainder of the clue works.

(Other definitions for cue that I've seen before include "Signal to players" , "Snooker player's stick" , "Prompt; signal" , "Potter" , "Hint on stage" .)

I've seen this clue in the Evening Standard.
