Standings over time

Daily standings ordered by winning percentage (wins over decisions) at the end of each day. Teams tied on percentage share the same rank, so lines can overlap. Official tiebreakers such as head-to-head records are not applied to the daily series.

Win-loss calendar

A tall dark cell is a win, a short light cell a loss, and a thin line a tie - the heights keep the chart readable even without color. Doubleheaders split the day's cell vertically.
