I also agree these coaches think this straighter (A to B) hand-path demonstrated results in a quicker and shorter swing.

I have charted many of these swings and found that the straighter a batter ‘s mechanics extends the hands, the longer the swing and the longer it takes to bring the bat-head to contact. Andy used Sammy Sosa as an example of a rotational swing. See clip http://www.youthbaseballcoaching.com/mpg/sosa_sammy3.mpeg

At frame 18 he makes contact. 4 video frames (4/30 second) = .13 sec. The more linear swings I have charted (Pros included) took 5 to 6 frames. --- Now start at frame 14 and see if Sammy has a long swing to contact. Note that at contact, his back-elbow is still in the “L” position at his side. The back-arm is nearing full extension with linear mechanics – 8 to 10 inches farther out to contact.

> Extension isn't the problem. It's how the hitter reaches extension. On video you can tell when a hitter is driving that top hand or when they are using rotational mechanics as you define them. But', extension is reached in most cases.

it may be that a particular clip here or there shows full xt, but generally in the major leagues hitters do NOT achieve full xt..their top arm is in the "L" position at contact...it's not a question of how xt should be reached because it should NOT be reached...one exception, and that is that generally the farther the oitch is outside the closer the hitter will come to full xt...
