The statement that sidearm pitchers are "more susceptible to reduced elbow valgus torque" is contradictory and confusing because it is wrong. It was a typo in the original abstract that was later corrected (it is actually "higher" not "reduced"). Here's a link to updated one: http://sdchp.com/AJSM_2009.pdf @Trip Yes you are correct.

Second, he is lifting his drive heel off the rubber sooner that before. It also appears that he is landing a bit more closed as well. His arm slot seems to a bit lower with more forearm flyout. Finally he is not rotating his shoulders as fully during his follow-through, look at the 5's on the back of his jersey. I would say he is over-rotating away from the plate and that forces him to start rotating his hips earlier, instead of turning the hips as late as possible. The end result is his hips have slowed down and causing him to land closed. He then has to throw across his body which shows up in his shoulder rotation in the follow-through. His velocity has decreased because of an inefficient hip turn and more energy is going around his body instead of being directed toward the plate.

It's tough to watch both at the same time, but it seems like his arm may be a little slower to vertical position this year. Maybe. Again, tough to tell. Any way we can get a video that pauses at foot plant? Aside from the stirrups in 2010, I don’t really see too much difference.

He seems to turn away from home plate during his leg left more in the right one but it could be the camera angle. I’m also not sure what the difference is.

I think it's pretty hard to tell from this, though. I also tried to look at his base, but that looks pretty consistent. Pretty much have no idea what I am supposed to see from this, so I am very interested to hear the full explanation. It seems like he is rushing in the right one.
