The one pitch I'm struggling to frame is the low pitch. I've heard a couple techniques on this, what do you guys prefer?

First off, you'll learn the umps strike zone very soon in the game. If you can get really low, and I always trained my catchers to be as low as they could be, on their insteps, butt almost touching dirt, then a low pitch may come right to the mitt. If you have to cherry pick or turn the glove down, its probably a ball anyway, and you may be waisting your time trying to frame a pitch below the strike zone.

Agree with Coachric.

Get as low as possible. This takes flexibility, with legs splayed out and butt almost in the dirt.

Soft hands.... that is the key to catching those tough pitches usually because you tense up, watch Brad Ausmus, especially he catches THE ROCKET aka Roger Clemens he just lets the ball come to him, no stabbing whats so ever!

strong wrists also help with framing the low pitch. just something i learned from getting really low. at about the 3rd inning my legs and hips are loose enough to touch my butt to the ground, but i rarely do becuase it takes away some "sway". i get really low but high enough to get to the wild pitchs. i only sway because when i call an inside pitch and its a foot outside then you have a hard time catching it. learn a good medium of how low you should get unless you can trust your pitchers to hit there spots consistenly then you can get as low as you want.

Heres how I frame the low pitch and my theory.Think what you will

On a pitch inside or outside you are framing east to west.On a low or high pitch,you are framing from north to south.Let the ball come to you and recieve it smoothly.Widen out your stance for maximum flexibility.
My method for framing a pitch is I slowly(I mean very slowly)am already moving my glove to the plate,or to the corner of the plate,you have to have good hangs and quick wrists for this technique.This makes the distance and movement for your frame minimal.

hope this helps some
