Then the umpires kicked it because NPF rule reflects NCAA and other than a minor clarification on a possible obstruction call, the rule is the same as USA/ASA. The only way it is an IP is if the pitcher intentionally rolls the ball toward the plate
Thank you for the correction MTR. The ball slipped out during delivery, went straight up about 20 feet or so and landed behind the circle. It was called an IP for whatever reason. At least now I know.
