Baseball gear
I think it could be either:
'baseball gear' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bats that I've seen before include "Bonkers (sl.)" , "Night-flying creatures" , "Hits" , "Hutton and Gilligan" , "Take a stab at the night creatures" .)
'baseball gear' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Another definition for mitt that I've seen is " Baseball glove".)
