Intentionally Dropped Line Drive?

[HawkeyeCubP]

HTBT, but as the OP reads, I don't think this is an intentionally dropped ball, at least by the ASA rule set. (I am, however, completely uneducated on USSA, so I don't know there.)

ASA POE 30 clarifies that the ball must actually be caught and then dropped. Unless the knocking to the ground involves the outside (perhaps backside, as I've seen done many times) of the glove and the fielder's other hand guiding/knocking the ball down, I don't have an intentionally dropped ball in this situation in ASA, since it's physically impossible to catch a ball for an out using only the backside of the glove without the assistance of the other hand.
