RSPA Rule Changes For 2025
Updated January 4, 2025Waiting for any possible rules changes resulting from the switch to NSA.
RSPA Possible Rule Changes for 2025:
• We have to look at is which rules we want to adopt from NSA
and any existing RSPA rules that we want to change.
With the merge of SPN-SPOA and the rule changes there, they are not that far off from NSA rules.
But we will look at all rules and see which rules we want to adopt.
• We will discuss the following possible rule change:
- going to 1 and 1 count; using "big ball-small ball"; pitchers mask mandatory; distance between bases 65’ or 70';
female batter option to walk; male/female pitcher-catcher combination; pitching arc 6’-10’ or 6’-12’;
bunting; stealing; home run rule change from an out to a single.
We sent out a survey to all RSPA team reps and the response was
to keep rules as they were for all suggested rule changes.
Other Rule Changes for 2025:
• ONLY ONE RSPA MEETING FOR 2025: Tuesday, April 29 at location TBA.
A representative from every team MUST attend the RSPA meeting.
If balls and/or team packages are not picked up, the team will forfeit their supply of balls.
• Team uniform rule (matching color shirts) is in effect for 2025.
• The official ball for 2025 will be the Louisville Slugger NSA Canada 12"
COR.52/300 Softball Optic Yellow- LSSB52CALYL. Teams may use up Worth "Hot Dot" balls.
(Based on the responses to the rules survey it is very unlikely that we will switch to small ball-big ball).
