I never could see what they were even calling in the replays. They looked far more legal than all the others that are known offenders. Awesome game though. I think I would have walked Bell. The pitch she went yard on was a great pitch and 90% of most batters couldn't have even made contact with it much less put it over the wall. There's a reason Bell has the number of hits she does.....pitchers need proceed with extreme caution.
I've been hearing from the local college umps that they have been told to enforce having both feet on the pitching rubber at the start of the pitch. I have been seeing quite a few calls where the pitcher is either stepping back or forward or even just slipping off the rubber and creating a visible gap before the pitch starts. Apparently this is the pitching sin they want enforced for this college season.
Leaping around like a kangaroo is still not getting called all that often unless it is either really obvious or the coaches start chirping about it. Though honestly I have seen more legal pitchers this year than I have seen in past years.
