There is a way a pitcher could pitch a perfect game in mid-season with no changes in the batting averages of the opponents.

Leadoff guy takes ball 4, and the pitch gets away from F2 and rolls far away. BR makes it to 2B safely but is called out on appeal for missing 1B. The next 26 batters also take ball 4 and the same thing happens. So there would be 27 outs with no one reaching 1B safely, and because no one would be charged with an at bat, nobody's batting average would change.

The guys who have monkeys working at typewriters say that eventually such a game will be played.

In 1964, I saw the Baltimore Orioles score only 1 run against the Yankees on a single, a triple, and 3 more singles.
