Batting with school cricket, for example (6)
I believe the answer is:
insect
'cricket for example' is the definition.
(cricket is a kind of insect)
'batting with school' is the wordplay.
'batting' becomes 'in'.
'with' means one lot of letters go next to another.
'school' becomes 'sect' (I've seen this before**).
'in'+'sect'='INSECT'
(Other definitions for insect that I've seen before include "A fly, for instance" , "Fly, say?" , "The entomologist studies this" , "fly, perhaps" , "Small animal with six legs" .)
