How these lists are ranked
Everything on this page comes from the same season files the charts draw, with standings read as each day ended. All 92 charted MLS races from 30 finished seasons enter: every conference and Supporters' Shield race from 1996 to 2025. Wild card races are not ranked; their story is the playoff cutoff, not first place. The 2026 season joins these lists when it ends. When the same two teams finished first and second in more than one charted race in the same season (a division and its conference, or a conference and a league-wide race), the narrower race keeps the row; that folds away 12 repeats here.
Tightest finishes ranks races by the final gap between first and second place, in points. Ties are broken by how late the winner took first place for good, then by lead changes, then oldest first. Two teams the standings cannot separate are shown as level, with no winner named; where the league settled such a race another way, the linked race page tells that story. A margin of zero with a winner named means the race was decided on points per game, the league's rule for uneven schedules, or on wins.
Most lead changes counts a change only when a new team passes the leader outright. A day spent tied on top stays with the team already leading, so a tie can never inflate the count.
Most days within three points counts the days on which this race's teams played and the top two ended the day within three points of each other, the most a single result can make up. Days a league stood idle (a strike, a pause) are not counted: a frozen gap says nothing about a race.
Only finished seasons are ranked. Seasons shortened by strikes or other stoppages count as played; every irregularity in the record is listed in the data notes.
