Exactly Jason..cant quite explain what I see but I see something... I played baseball up until junior year of college and that expereince helps me with baseball. Both eyes open is crucial..not only for helping to time but also when its fouled at you its easier to pick up the ball and dodge. I am very good doing this with my right eye in the viewfinder...however not so good the other way. And depending on where/what your shooting, being able to use both really helps.
and luck helps a lot too.. if they are slightly "behind" or "in front" of the pitch it is easily out of frame...of course those usually arent the best swings anyway.
For what its worth I prefer the "pose" after the swing much more as it often highlights action and a good face shot. Something like this...
