The players whose season belongs to this club, by position and then by dbWAR. A player traded mid-season is listed with the club he played most of his games for, so a deadline arrival may appear on his other club’s page instead.
Each rectangle is a player, sized by his share of the team's hits; darker means a larger share. Top 30 contributors. Select a different statistic above, or click a player for his page.
Day and night divide the home schedule, and so do weekend and weekday. The road line is a different question.

Announced gate — tickets distributed, which is the figure every reference publishes and is not the same as people through the turnstile. A game the feed reports no gate for is left out rather than counted as empty. 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. 175 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
Seattle Mariners are 89-73, a .549 win rate, while their -34 run differential implies .478. That is about 12 wins ahead of it, usually a mix of bullpen sequencing and one-run luck.
