Baseball · WBSC / Rule 07
WBSC event formats and extra innings
WBSC · 2025–2026In short
The supplied appendix sets different lengths and tie-break rules by event.
Event length and tie-break
U-12 World Cup games use 6 innings; U-15, U-18, U-23 and Women’s World Cups use 7; Premier12 uses 9. If tied afterward, every extra inning starts with runners on first and second and no outs. The batting order continues, with the preceding batting-order players occupying the bases.
Run-difference endings
For U-12, a deficit of 15 after batting through 4 innings, or 10 after 5, ends the game. The other listed World Cups use 10 after 5. These run-difference rules do not apply to the championship game, but do apply to bronze-medal games. The appendix does not state that same run-difference rule for Premier12.
Independent explanations and translations, not official federation publications. Based on the supplied WBSC Official Rules of Baseball 2025–2026, including its event-specific appendices.
