  1. The dropped third-strike rule does not apply. Whether or not the 3rd strike is caught, the batter is out. The ball is still live, and runners may steal 2nd and 3rd bases. Runners may not advance to home on a dropped third strike.
  2. Base stealing is permitted under the following rule exceptions:
    • Runners may not steal home or advance to home as part of stealing a base or bases.
    • Runners may steal one or more bases per pitch, including a batter who receives a base on balls.
    • Runners starting at third base may not steal home but are liable to be put out if they are off the base when a play is made on them. See rule #4 below for clarification on how runners may score a run.
  3. A 5-run limit per inning shall be imposed for the first two innings of the game. All subsequent innings shall have no run limit.
  4. Runners may only score on:
    • A batted ball
    • A base on balls or hit by pitch with bases loaded – the runner on third is forced to home under this situation.
    • An awarded base when the ball goes out of play to include a pitch that goes out of play

The Registration “Year”

We are currently in the 2024 season. The softball “year” for USSSA runs from August 1 to July 31. All tournaments scheduled after August 1 are considered the following year’s events, and in order to participate in them, a team must be registered for the current year (Ex. August 1, 2023, is part of the 2024 Season). In short, all the created teams and all submitted rosters for a season expire on July 31.

Under the USSSA website, a manager establishes a one-time account, and then creates teams under that account from year to year. On or shortly after July 1, managers should create their team for the upcoming season, particularly if they plan on playing any USSSA tournaments between August and December. Otherwise, they can wait until next year to create their team.

Before a manager can create a team, he/she must complete a background check through their manager’s account. Once that is cleared, he/she can then create their team. Managers must enter their roster online each year, print the roster, and have each player and parent sign it. One thing that makes entering your roster easier the second time around is that any player that previously played on a team that the manager has under their account will already be in the system. If the manager wants to retain that player from a previous year, then all he/she has to do is highlight the player under the “Add Former Player” section and hit the submit button.

NOTE: If a player has played a prior season with USSSA, do not create another account for this player. Please make sure the correct spelling was used from the prior season. If a player cannot be located, please email [email protected]

Roster Age Eligibility

The age cut-off is still based on the calendar year. The age eligibility for teams changes on August 1, the annual start of a new season.

It may be easier to think of it in these terms: What is the age of the player as of December 31 of the current calendar year? That is the roster age for the player in the season that will start on August 1.

Below is a breakdown of age eligibility. Managers must be aware of the age eligibility cut-off in order to properly classify the age of their team for the fall season.

Insurance Requirements

Proof of adequate insurance must be filed with the State Office two weeks before the team’s first tournament. The insurance need not be issued through USSSA but must provide at least $1 million in liability coverage. Every year some teams think that they’re adequately covered when they either have no liability insurance at all (only accident coverage) or have very low liability limits.
