Catcher's Must Get Behind the Batter On Throws To 3rd
I can't stress enough the importance of getting behind the right-handed batter on a throw to 3B. Just shuffling your feet most often won't give you enough room to make a consistently accurate throw to 3B, and very often you'll meet the end of a bat or a helmet with the ball, or worse your hand.
For the right-handed catchers, make sure your right foot gets behind your left foot, and far enough past the left foot that it also clears the batter's back foot before you stride into the throw to 3B. This will get you far enough behind the batter to avoid an issue like Kurt Suzuki of the Nationals experienced this weekend.
