Wicket stifling your spin (6)
I believe the answer is:
gyrate
'spin' is the definition.
('gyrate' can be a synonym of 'spin')
'wicket stifling your' is the wordplay.
'wicket' becomes 'gate'.
'stifling' means one lot of letters goes inside another.
'your' becomes 'yr'.
'gate' placed around 'yr' is 'GYRATE'.
(Other definitions for gyrate that I've seen before include "Spin at speed" , "Revolve, whirl" , "Spiral about a point" , "Move in a circle or spiral" , "Spin around" .)
