Dive forward, catching ball: take it easy (6)
I believe the answer is:
lounge
'take it easy' is the definition.
(I've seen this in another clue)
'dive forward catching ball' is the wordplay.
'dive forward' becomes 'lunge' (to lunge is to thrust or dive forward).
'catching' is an insertion indicator.
'ball' becomes 'o' (O looks like a ball).
'lunge' placed around 'o' is 'LOUNGE'.
(Other definitions for lounge that I've seen before include "Waste time -- glue on (anag)" , "Living-room" , "Relax in sitting room?" , "Sit or recline comfortably" , "Recline lazily; room" .)
