Infield fly rule, sorta

[Dakota]

For ASA, the ball must be legally caught and then dropped to be an intentionally dropped ball.

Guiding the ball to the ground, batting it to the ground with the glove, letting the ball bounce out of the glove, or intentionally not catching it is a legal play.

As described, this is neither a IF (because, as already noted, a line drive cannot be in IF) nor is it an intentionally dropped ball, because it was never legally caught.
