catcher int. question

[Mr. Wonderful]

how is this scored for the books when a batter is awarded first base because of the batter coming into contact with the catcher (mitt) on the swing?

[hit4power]

It is scored as an error on the catcher. Generally, anytime a runner (or the batter) advances a base as a result of obstruction (even if the obstruction is on another runner), an error is charged.

An error is charged on the catcher, but the batter reaches first on Int/Obs so it doesn't count as an At Bat and has no effect on their batting stats.

b - Times at bat (AB) - do not include sacrifice bunts, sacrifice flies,
hit by pitch, base on balls, gaining first base by interference or
obstruction, or an incomplete turn at bat,
