On a pick, advantage applies if the disc is in the air or if the thrower is in a throwing motion; advantage does not apply if the disc is not in the air and the thrower is not in a throwing motion. Referees should immediately whistle if there is no advantage and delay the whistle if advantage applies.
If advantage does not apply, or if advantage applies, the pick affects the play, and the offense catches the disc, then the original thrower maintains possession and yards are marked from the original thrower.
