Club losing wickets, and advantage (4)

Ross

I believe the answer is:

edge

'advantage' is the definition.
(having the edge is having an advantage)

I don't understand how the remainder of the clue works.

(Other definitions for edge that I've seen before include "Bind" , "Keenness" , "Move furtively; intense quality" , "Bite" , "incisiveness" .)

I've seen this clue in The Telegraph and The Times.
