Scroll down to the bottom of this diagnostics page. Not that when Santana is set to release the ball, his pitching arm side elbow is shoulder height and his arm is cocked upright as is proper. Compare that to the image of Liriano at the release point at the top of this article. His elbow is above his friggin' ear and his arm is pointing palm-side down to the dirt in the classic inverted W. Santana has average mechanics...Liriano's mechanics make women and children cry.
