"Biomechanical Comparison of Baseball Pitching and Long-Toss: Implications for Training and Rehabilitation", Flesig et al JOSPT 5-11.
Basically the authors are saying that you get to a point where kinematics are changed too much to have any transfer value to pitching. That point is well taken. What I'm wondering though is if it will be beneficial in producing the soft tissue adaptations to the shoulder & elbow that might carry over to the sport. And, will adding in a little long toss a few times a week be enough to interfere with the motor learning process of pitching. Is long toss something we need to throw out all together?
Remember Frans Bosch's definition of strength training; "coordination training with resistance", which states, "an ideal form of training should be able to provide a greater workload than an athlete's current stress handling capacity can deal with, while also complying with the criteria that must be met for an optimum transfer of training. However, overload and specificity are not mutually compatible. If one wants to include a large overload in training, then one must always deviate from some of the characteristics of goal or competition oriented forms of training" (Bosch '05).
Does (long distance) long toss meet this criteria...provided it is done in the right context?
