What is Appendix G? NCAA rule allowed UCLA home run vs Tennessee in WCWS – USA Today

Tennessee softball’s elimination game against UCLA in the 2025 Women’s College World Series on Sunday at Devon Park in Oklahoma City sent fans across the country to a place few would have anticipated when they tuned into the matchup — the NCAA rule book.
With the Lady Vols leading the Bruins 4-2 in the top of the seventh inning with two outs, Megan Grant smacked a two-run, game-tying home run off Tennessee flame-thrower Karlyn Pickens. 
What initially appeared to be a straightforward — albeit incredibly consequential — play soon became a subject of controversy.
After rounding third base, Grant headed home, with her teammates waiting there to mob her. Grant, however, did not initially touch home plate and only did so several seconds later after teammate Alexis Ramirez prompted her to do so.
Umpires prompted a lengthy video review, which ultimately resulted in the call on the field being upheld, even though Grant had not originally touched the plate and had been assisted to go back and make contact. However, the play wasn’t reviewable according to Appendix G. The decision sent the game into extra innings.
The ruling led to frustration and outright anger from the Tennessee dugout, but for those watching the game, it created some understandable confusion. What, exactly, is Appendix G?
Here’s a closer look at Appendix G and how it factored into the umpiring crew’s decision in Sunday’s WCWS game between UCLA and Tennessee softball:
Tucked away in the 185-page 2025 NCAA Softball Rule Book is Appendix G, which legislates video review in the sport.
The appendix, which covers two pages in the rule book, details what plays are subject to video review and criteria for using video review.
Appendix G outlines 12 different plays and scenarios that can be reviewed. While there is a section for flagrant and malicious contact, that doesn’t appear to include actions like Ramirez nudging her teammate to ensure she touches home plate.
Here’s a list of the plays subject to video review, according to the NCAA rule book:
Note: The crew chief may not initiate a review of runners leaving early on a pitch. This review is only allowed by a coach’s challenge.
