Day and night divide the home schedule, and so do weekend and weekday. The road line is a different question.

By season

Every home game this season was played with no crowd admitted. The zero is the season, not a missing number — which is why it is shown rather than left out. Seasons before attendance was carried into the lake are absent from the trend rather than shown as zero.

By season

Regulation games only, in minutes. 186 minutes this season.

Elapsed time from first pitch to final out. The feed does not itemise delays, so a rain delay is inside these numbers with no way to subtract it. Games called early are excluded — five innings in ninety-three minutes is not a short game — but they still count in attendance, because the crowd turned up.

Record versus run differential

Arizona Diamondbacks are 25-35, a .417 win rate, while their -26 run differential implies .458. That is about 2 wins behind it, which tends to regress upward.
