As for the recovered balls there was another (different) MD C team that was not affected by the heat, using all their bumps with relative ease. A different team collect HR balls that the alleged team left behind and cut the covers off of them. They scored plenty of runs on Saturday but was way down after the accusation Sunday. Hasn't been much updated on this other than that.
Bob and Carol require teams to use particular balls (Gold dot extreme's for E&D) which they sell at every event. I'm not sure what C and up have to use currently. (I'm just a lowly D coach)
