Softball standings are ranked like baseball’s: winning percentage first (W ÷ games played), with games back to show the gap to the leader. Leagues that allow ties, usually because of time limits, count a tie as half a win and half a loss.
Because softball games are short (seven innings) and blowouts are common, run differential matters more than in most sports. Tournaments seed bracket play from pool play records, and when teams are level the run differential decides it, which is why so many cap it per game: a 15–1 win counts for no more than the cap.
Fast-pitch and slow-pitch keep the same table. The difference is the scoring rate — slow-pitch scores are higher and run caps per inning are common, which changes how far apart run differentials end up.
