Playing Catcher
Catcher is No. 2: every pitch, every throw home, and the whole field in front of him.
How it actually works. Balanced squat, glove relaxed and giving a clear target. On a ball in the dirt the first move is forward and down to block. On a steal it is up and through the throw, with the feet replacing each other under the catch. He calls out the outs, the runners and bunt or steal alerts, and he leads the cutoffs and relays on throws home.
Why it is done, and when it is wrong. Catcher is the hardest position on the field and it is the one with the most influence, because every single pitch goes through it. That is why the catcher has to be the voice of the defense. He is the only player facing the whole field, so he is the one who knows first where the throw needs to go.
What people get wrong about it. Youth catchers stand up too early and lose low strikes, stab at pitches instead of receiving them, take too long to get the ball out on throws, and block with their chest straight up so the ball bounces away instead of angled forward so it drops in front.
At Little League and travel ball. Put your smart, tough, vocal kid back there. A catcher who can block and talk will save more runs at 10U than a shortstop with a great arm.
