'cricketer's not' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'speedy around a stadium' is the wordplay.
'speedy' becomes 'slower' (I am not sure about this - if you are sure you should believe this answer much more).
'around' indicates putting letters inside.
'a stadium' becomes 'bowl' (synonyms).
'slower' going around 'bowl' is 'SLOW BOWLER'.
