Abstract: A baseball swing training aid includes a housing and a lid for retaining a batting tee in a first or storage configuration and in a second or use configuration. In the first configuration, the batting tee is stowable on an underside of the lid such that the tee does not interfere with the lid's attachment to the housing. In the second configuration, the batting tee base attaches to a slot formed in the lid to extend the tee upwardly for baseball swing training. Accordingly, the tee is easily changeable between the first and second configurations for fast setup, storage or transportation.
