I had always thought of “tunneling” as an analytical quality—something that you might work on through pitch design or pitch sequencing (with a Rapsodo scatter plot, for example)—as opposed to the act of literally trying to throw the ball down a tunnel. So improvements in tunneling would come from figuring out what existing pitches play off each other—rather than trying to develop new ways of throwing those pitches so that they better resemble one another. The only training that you might do would be to make sure that all pitches are released from the same spot, which for softball pitchers is a lot easier than in baseball, since softball release points are virtually identical from pitch to pitch.
All that said, I do wonder if the hula-hoop concept might work as a low-tech check on which pitches are in fact tunneling. The first article below reference a “tunnel point” of 23.8 feet for baseball (the point where the batter has to make a decision), so maybe about 40-45% of the distance from release to the plate, and an average differential at the tunnel point of 10 inches between pitches (for MLB pitchers). So maybe a hoop of similar diameter, set at about 17 feet for softball, might work. The second article below also references that not all pitchers rely on tunneling through a small window (contrasting Greg Maddux’s small tunnels with Bary Zito’s big tunnels). I am not sure that’s as relevant to softball either, since softball movement pitches don’t break nearly as much as in baseball. (You don’t see anything that resembles Zito’s curveball in terms of speed or amount of break in softball.)
Would be curious to hear how this works for folks in practice. I think you would need a lot of trial and error to get the hoop at the right distance and diameter.
