Babe's all-out game (8)
I believe the answer is:
baseball
'game' is the definition.
(I know that baseball is a type of ball game)
'babe's all-out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'babes'+'all'='babesall'
'babesall' with letters rearranged gives 'BASEBALL'.
(Other definitions for baseball that I've seen before include "American team game" , "Bale labs out for this game" , "Lea blabs about the sport" , "SPORT/GAME" , "Mainly North American game" .)
