What does Lance Berkman take off when he reaches first???

Question

He takes it off what looks like his thumb its yellow and i always see him put it in his mouth then sticks it with his back pocket with his batting gloves and its just bugging me WHAT IS IT?

Answer 1

I'm not sure, but it's probably some kind of wrist guard or hand/finger guard to protect him while batting.  Many players will use special guards of various types while batting, usually for extra protection from previous injuries to that previously injured area.
