>>> However, you should note that dead pull hitting requires the bat-head to rotate 45 degrees past a normal centerfield position. This is how I came up with the 225 degree arc. <<<

Rotating the bat 45 degrees past perpendicular (from hitting the ball straight away) would NOT pull the ball down the third base line (“dead pull”, as you referred to it). Having the bat at 45 degrees would cause the ball to exit the bat parallel with the back of the plate or the back-stop. This means it would be hit 45 degrees to the left of the third base foul line.

But, due to the “hooking effect” generated from impacting the outside part of the ball, about 17 to 19 degrees past perpendicular is closer to the actual maximum.

> I wonder how many real good hitters even know how to spell geometry? If you want to be taken seriously as a hitter or hitting coach, acting like a nerd won't do it. Using math to talk about the swing is very nerdish and won't teach anyone how to make a good swing. A good swing is not complicated, but some people want to reinvent the wheel, and that is what is happening with BHL. You never answered Teacherman's question, and never answered any of my questions.Talking about Mel Ott and how he hits is nonsense when there are about 3 clips of Ott in existance. Bonds uses a 34" 31 1/2 oz bat and chokes up 2 inches. I doubt very much if he thinks much about geometry.

give BHL a break...there is nothing wrong with searching for a mathematical or a scientific model...in the quest for The Perfect Swing Model (which may never be found)we all do it here and at setpro...i don't think Bonds thinks about math or science but i bet he also does not think about top hand torque, chp, scap load or any of the other stuff we discuss...but that won't stop us from our search for The perfect swing Model, will it?

and Jack, please don't misinterpret my remarks, because i do think all the "stuff" i mentioned that we talk about is good...my point is simply that just because most major leaguers simply do it does not mean that we should not, in our own way search for Truth....and i happen to think that any math and/or science that is added to the discussion will ENHANCE our quest for Truth, not detract from it....

p.s.point on bonds not thinking about math is well taken...i might also point out that once bonds said that when he hits he throws his hands at the ball...so obviously he is not thinking about Pure Rotational Mechanics either...or how about this one? Griffey jr has said that he is a "weight shift hitter", not a "rotational" hitter...al kaline said that contact is made at full x-t, yet video proves he himself contacted in the top arm "L" position...and we, myself included have the nerve to anlayze these players and tell them that WE understand their swing better than THEY do!!!!!
