And recently in the baseball world . Have seen catchers in the bullpen holding a mini-club instead of a catchers mitt. Then using the weight to mock, sweeping or 'pick' moves to scoop the ball out the dirt. Looked to work the entire arm chain from hand, wrist, forearm, elbow, shoulder.Those are clubbells, basically the modern version of the Persian meel or the Indian Jori. They have been around for maybe 20 years now, I think Scott Sonnon pioneered them; you can typically get them in weights up to 15 kg, more rarely 20 kg. Originally, they were used by wrestlers to do pummeling drills etc., but have become more mainstream. I wouldn't say they are commonly found in commercial gyms, though - only in places that focus on "functional fitness".

or just something for ESPN to promote bc its baseball and half the viewers are asleepInteresting, but looks risky to me - in the sense that you may screw with a fine motor pattern. But what do I know about baseball - maybe it works as contrast training or whatever.
