During tonight's scrimmage, one of our hitters reached base on catcher's interference. Interference was called because the catcher's glove hit the bat during the swing. As a result, the hitter was awarded first base.
If the batter would have reached base on a hit and all other runners had safely advanced, the play would have stood and the interference would have been ignored. But, since the ball was caught on a fly, the interference applied and was a benefit to the offense.
For scoring purposes, the catcher is charged with an error. The interference is ignored entirely for purposes of the hitting statistics. In other words, the batter is not charged with a plate appearance and is not credited with reaching base.
We tend to see catcher's interference four or five times during a season. Sometimes, we see it twice in the same inning!
