Not sure if I could locate it immediately, but I am positive there is an NFHS ruling or case play which does require the player to pick the ball off the ground before the runner.

I am equally sure that ASA and NCAA both allow the umpire judgment of control if the player can come up with the ball cleanly, even after the runner has passed, as long as the player doesn't do anything additional (ie, now wrap fingers around, or tighten the grip) in between. Although you can more easily sell "no control" on the trap than control bringing it up later, the ability to sell it shouldn't affect how we call it, should it?
