This is an Easton Cyclone Baseball Bat, Model BB1. It is 33 inches, 30 ounces, and 2-5/8 barrel. This size is generally used by those 5' 1" to 6' 1" so it can be used by a youth or adult or for softball. This bat has some chips off the paint and the grip needs to be replaced as black is coming off but it is still usable.
