  1. They both pitch behind very stiff front legs I feel like that’s dropping efficiency from their mechanics.

  2. Love Reed’s arm mechanics. Has great arm action while maintaining his deception.

  3. All pitchers either keep their legs stiff or straighten their leg as the shoulders rotate. This does not affect release point. Roy Halladay is one of the most durable pitchers despite his 2012 injury, and he keeps his leg stiff. Verlander is probably the most durable pitcher and he straightens his leg which theoretically could increase the speed of the shoulder rotation.

    I’ve heard scouts say pitchers land on stiff legs which supposedly could affect control or extension. I don’t really understand this sentiment. There is an angle between the post leg thigh and hamstring which might be the “stiff leg” when low enough. When the post leg hits the ground, the energy is sent back up the leg where the higher this angle, the more energy is used to “push” the leg backwards horizontally. I haven’t seen any studies, but this might potentially affect shoulder rotation and trunk flexion. I personally don’t believe it affects efficiency, which is probably defined as mechanics that produce the most velocity with the least perceived amount of effort. Johan Santana lands on a stiff front leg, but he still produced 97 mph heat in his prime from only a 6′ frame.

  4. What about his arm action makes you think they are great?

  5. Just out of curiosity, why is it that you do not include sound in your clips? I don’t have an opinion either way, but I’ve noticed that bullpen banter usually does, and was curious if there was any rationale behind these decisions.

  6. I’m curious what your thoughts on Paco Rodriguez are, Mike.

  7. I’ve talked to the Bullpen Banter guys at length about this. For me, sound is an unnecessary annoyance. There’s nothing worse than checking out a video while listening to music and being distracted by sounds at the park in the background. Additionally, if I’m shooting video while talking to a scout, I don’t want privileged information showing up on a video.

  8. I never saw him in Chattanooga. From his debut, he should be a solid reliever for quite awhile.

  9. Garcia seems to drop his arm a tad when facing Chiang. Unfortunately, that was the only lefty hitter Garcia faced that game. Mike: did you notice that and would it be something that the coaches would try to minimize at this stage of Garcia’s development?

  10. garcia is ready for the show! put him in the pen.. the guy isnt a typical prospect.. dominated in cuba and those guys can flat out ball. garcia and paco would be great middle relief specialist! now cut the BS and go get a 3b. ty wiggington or brandon inge would look good in dodger blue and hey.. inge can catch.. at least insurance for cruz and fedorwitz

  11. Reed looks like he is stepping to the LHH batter’s box as opposed to directly toward home plate. Is this the camera angle or is this how he is able to throw across his body to increase deception? If the latter, is this delivery sustainable?
