Saw it - thought the same thing.
One thing I found interesting; They called illegal pitch on Jackie Traina a couple of times because she didn't have her hands together for 2 seconds ("International Rules") yet there's also a rule that the batter can't step out of the box during her entire At Bat. Presumably the batter's rule is to speed up the game. I think that the pitcher's rule kinda offsets any time gained by the first rule...
Don't ever believe anything these so called "expert" commentators have to say about the rules of the game!
This is the same bunch that mangled the substitution rules during the college World Series, commonly interchanges the words "obstruction" and "interference" as if they are the same thing and have repeatedly made idiotic comments like "the hands are part of the bat".
International Softball Federation (ISF) rules DO NOT require the batter to stay in the box between pitches. ASA rules do, with some exceptions (after swinging, if forced out by a wild pitch, if catcher goes to talk to the pitcher, and a few others).
I'm not sure what the announcers were claiming, but the ISF rule is that the pitcher must hold her hands stationary, in front of the body, for not less than two and no more than five seconds prior to starting the pitch. This differs from ASA, high school, NCAA, etc. in that none of those require the hands to be held still when brought together. They allow the hands to be in motion before, during and after they are joined.
