I read coach james as saying that with internal rotation of the lead leg "into the hip socket" will create an inward/rearward movement or "rotation" of the pelvic girdle which is somewhat correct...but needs a lot of leeway or a lot more words of explanation as to all of the other factors to make it an actual, complete true statement.

But in the few words he used, and with a little imagination, I'm OK with the general idea of his statement. IOWs, the lead leg can/does "assist" in creating rearward rotation of the PG "around" the rear leg....IMO.

Do you coach the assist? And did you mean around the spinal axis? LOL Also you have a wonderful imagination!

All depends on the hitter. Sometimes yes, but more oftentimes no...because it gets taught indirectly when teaching getting into the "hitting position" ("position of power", "swearing in position", "launch position", etc....take your pick), and is then a determinant of the hitters own style as to how or how much they use the lead leg to assist their coil.

And did you mean around the spinal axis? LOL

No, for coaching purposes, and mental imagery (BAM!...hahaha) for the student I mean "'around' the rear leg".

Also you have a wonderful imagination!

Only way I can understand some of the things that get posted at these hitting websites half the time...but thank you.

Is it your observation that initial hip rotation occurs as the front leg pushes into the hip socket?

Not my observation... it’s more of a question

Several years ago BM put together a series of swing segments that showed that rotation began prior to the action you describe.

At one point Doc Yeager had a swing theory based on what you describe. I requested that he share his data with me. I reported back that his own data exhibited that rotation was initiated prior. He acknowledged that was the case.
