Just in case you didn’t already know, here is the Claw and Antlers explained for the Texas Rangers:
The claw was developed by minor league player Esteban German of the Texas Rangers. It’s basically an air high five to the dugout from a player on base who gets a hit.
Antlers signify speed, commonly given after stealing a base or beating out a ground ball. Josh Hamilton started this from hunting down a 10 point buck, which now hangs above his locker.
