Opener’s uncontrolled movement, breaking white sports club (6,5)

I believe the answer is:

hockey stick

'sports club' is the definition.
(club or stick used in hockey)

'opener's uncontrolled movement breaking white' is the wordplay.
'opener's' becomes 'key's' (keys open things).
'uncontrolled movement' becomes 'tic' (involuntary bodily movement).
'breaking' means one lot of letters goes inside another.
'white' becomes 'hock' (type of white wine).
'keys'+'tic'='keystic'
'keystic' placed into 'hock' is 'HOCKEY STICK'.

I've seen this clue in The Times.
