not recommended. Time and a place for everything. Mask stayed on entire time til top 7. Between innings , pitching changes, rotations. Again, not recommended.
I once made it to the seventh without taking it off once I put it in and said play. Players sent trainer of the female gender out with water for me. Mask had to come off for that.
You can say that about any missed call whether it's a pulled foot, strike or swipe tag. Sometimes plays develop where you are unable to be in the optimum position.
Those "mistakes" happen. And yes there are instances where you do not have an opportunity to get a good adjustment step. Never say never. There is no valid reason to miss anything if we do what we should but hey, there is not one person that is that good.
A runner is not allowed to wave his arms, throw an arm out, etc, intentionally to interfere with a thrown ball. This is INT regardless if contact with the ball is made or not. Contact is not a requirement for the INT to be called.
If the INITIAL throw retires a runner the INT is disregarded. If that criteria is not met then the batter is out and runners return. This is assuming that the batter is not out on strikes at the time of INT. HuskerUmp, where do you umpire at? I live in Waverly member of the CUA
