A player switching between travel ball and high school will notice a few differences. USA Softball needs four pitches for an intentional walk, while high school awards it without pitching. USA Softball's JO play allows an extra player, ends games on a 15, 12 or 8-run lead, and tournaments often play to a time limit. High school leaves the run rule to each state.

Many players play high school softball in the spring and travel ball under USA Softball rules in the summer and fall. The two rulebooks agree on almost everything. The table above lists the rules side by side; these are the differences that come up in games.

Intentional walks

In high school, the coach, pitcher or catcher just asks the umpire, and the batter goes to first with no pitches thrown. In USA Softball, the pitcher still has to throw four legal pitches, and the ball is live, so a wild one can let runners move up.

Bigger lineups in travel ball

Both allow the DP/FLEX. USA Softball’s girls’ (JO) play also allows an extra player (EP), a tenth batter, with or without the DP/FLEX, and in pool play a team may bat its whole roster. High school has no extra player.

Re-entry

In both, a player who leaves can come back in once, in her original spot in the batting order. See re-entry.

How games end

  • USA Softball: 7 innings, ended early by a lead of 15 runs after 3 innings, 12 after 4 or 8 after 5. National championships also stop starting new innings after 1 hour 40 minutes, and local tournaments often set 1:30 or 1:40.
  • High school: 7 innings, with no time limit. The run-ahead rule is set by each state association. See the run rule.

Equipment

Both require a face guard on the batting helmet. High school allows metal cleats at every level; USA Softball allows them from 14U. Bat rules differ too: high school accepts three certification marks, and USA Softball has its own approved and non-approved lists.

The same in both

Leaving on the pitcher’s release, the look-back rule, the legal leap and illegal crow hop, the dropped third strike, courtesy runners for the pitcher and catcher, and the 43-foot pitching distance for 14U and up.
