In the 50+ and older divisions, if categories/divisions need to be combined, the Equalizer Rule may be used.

Equalizer Rule: The older or lower division team will be given the choice of the following: (a) 5 Runs (1 per inning through innings 2-6); or (b) 11 Players on Defense and is the visiting team.

Team Rosters for Event #1 must be submitted a minimum of two (2) weeks prior to the Event. Maximum roster size is 20 Players.

Teams may adjust this Roster for each Event, but an Event's Roster must be finalized by the Wednesday before each Event.

Rosters are frozen as of August 9th (after Event #2).

Grandfather Age Rule

1)  In the 50+ to 65+ divisions, a maximum of two (2) Players that are one (1) calendar year younger than the division age will be permitted on each team.

2)  In the 70+ division, a maximum of three (3) Players that are one (1) calendar year younger than the division age will be permitted on each team.

3)  In the 75+ division, a maximum of four (4) Players that are one (1) calendar year younger than the division age will be permitted on each team.

These Players cannot have an A or B rating. Current and previous year’s Rosters will be used in determining a Player’s rating.

If a team is below 14 players they can request to use a player two (2) years younger. This request must be done by email to and approval is needed.

Short Bench Rule
A Player will be permitted to play on a team in a lower division along with his own team in the same tournament. This can only be done if a team is below 14 Players and they can only add to take their team up to a maximum of 14 Players. Any addition must be done in writing and submitted to the Registration Desk prior to the first game of the Event - it cannot be done during an Event. If a Player is ejected, they will not be able to play on either team until they sit out a game from the division they were ejected from. If a Players gets ejected from the team's last game of an Event and if their other team is still playing, they will have to sit out that next game and then would be eligible. A Player may be on more than one short-handed list. Please Note: This rule has been implemented in an effort to increase participation. Please do not abuse this initiative.

For the 2021 Super Series season, all bats used must adhere to the USSSA Licensed/Approved Bat Policy. To be legal, they must be marked with the “USSSA BPF 1.20” mark on its taper (known as the “Thumbprint”).  SPO will be using an aggressive Random Bat Testing Program.
