- "Knob at the ball" - We have used this in teaching. This is a very dangerous term if not demonstrated. If done improperly, this same term can promote bat lag. In my opinion, it has to do with less than 4 inches of he swing. We use this for "casters" who throw their arms away from the body. There are probably better phrases so someone share one. We don't use this much, if at all,at the high school level but do in clinics where we have to take all players and, to be honest, some have never swung a bat at all and so, they don't have any idea at all on the swing.
- "Arm extension" - Have to say that we really don't use this. I've heard it a lot and yet, I don't know where it happens in a swing until after the ball has been hit. The back elbow, in particular, is going to spend most of it's time in the swing close to the body and so, if you use this term, you are promoting "casting." JMHO!
- "Weak top hand" - We use this term a lot. The difference in a swing matching ball flight is so exact that if that top hand "drags" then the result is a foul ball or popup. I don't know of anyone else that uses this phrase but it works for us in viewing video of our hitters. It seems to address what is happening in their swing.
- "Let the ball get to you" - This is probably the most used phrase in our program. I've heard several college coaches speak on this. They all had different phrases to describe this same concept. My varsity assistant, who played at a top Division I school, like this phrase from his college days and so, we've stuck with it. This describes the hitters ability to "hit the ball where it is pitched" while keeping back. This helps us prevent opening up too soon, gives us a solid load before swing, enables us drive the ball regardless of pitch location and gives the hitter confidence since they have worked on three seperate pitches and know that they have repetitions hitting each. We have a drill for this but it is too complicated to type here.
- "Finish High"" - We use this term also. To me, it is the "tracks" of the swing. It tells you where the bat was with regards to swing path. It lets us know about spine angle.
Well, these are but a few terms. I tried to give opinions on some we use and don't use. I am hoping that we can have a thread with contributions where we all can learn. PLEASE ACCEPT THIS THREAD IN THE MANNER IN WHICH IT IS PRESENTED. Everything I've typed here is JMHO!
