4 & More Teams - Round Robin - Page Playoff Format


In 50+ and older, 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.



Team Rosters (for use in Event #1) must be submitted prior to May 13th, 2018. Maximum roster size is 20 Players. 


Teams may adjust this Roster for each Event, but an Event's Roster must be submitted by the Wednesday before each Event. A Player may be on only one Roster in a division, but may be on a team in a different division. A Player may only play in one division in any Event.


Rosters are frozen as of July 16th (after the 3rd Event).


Grandfather Age Rule

A maximum of two (2) 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.


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 12 Players and they can only add to take their team up to a maximum of 12 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 2018 season of the Masters Circuit, SPO will follow the USSSA Bat Certification Program. Composite bats must be marked with the new "USSSA BPF 1.20" logo on the taper of the barrel (known as the "Thumbprint").  Random bat testing will occur during all Events.
