USSSA Fastpitch pitching rules

That is not a gap in the rulebook. It is how most softball organizations work: the decision belongs to your league. So whatever your league requires is the rule, and if your league requires nothing, nothing applies.

USSSA sets pitching limits in baseball but not in fastpitch. Individual tournament directors may impose their own — check the event rules, which can differ from one weekend to the next.

USSSA also runs another program

USSSA's rules are not the same across its programs, and the difference is a real one rather than an oversight on this page: USSSA Fastpitch sets no pitching limit while USSSA Baseball does. If you coach both, expect them to behave differently — because the books do. See USSSA Baseball.

Your league is the rule

With nothing set nationally, whatever your league's bylaws say is the whole of it — and leagues vary widely. A survey of fifteen published league and tournament rule sets in September 2026 found per-game caps ranging from two innings to nine, weekly caps from six to thirty, some leagues counting outs rather than innings, and eleven of the fifteen publishing no limit at all. There is no common figure to quote you.

So the honest thing a planning tool can do is ask you and then hold you to your own answer. Even Innings does that: tell it once what your league requires and it tracks and enforces it everywhere — the lineup sheet, the arms box and the practice plan — and prints on the sheet that the limits are yours, not USSSA's.

Even Innings is a planning aid, not a compliance system. It cannot know what happened in a game, and it does not replace your rulebook or your league's own bylaws. Always confirm current-year specifics with your own league.
