So the ending, and moral, of the story is that karma did indeed bite, but not too hard.

The opponent took illegal batting practice off tees, which is specifically prohibited by the CIF playoff rules. We called and reported it to CIF and played the game under protest. Naturally the batting practice was filmed by multiple pissed off parents.
Once they found out, then we were told about the confirmation and that half of the team would be gone. You know, you could have told us the reason the day before and maybe we could have worked something out. We were also told that the use of the tees was a mistake and that the coaches weren't there to supervise the girls, who had set out and used the tees on their own. Well, the film proves the truth. The team did start practice one their own, with one adult who spent the entire game in the dugout with the team and was wearing a team shirt (but of course he was not a coach). However, once the actual coaches arrived, they stood there and watched the batting warm ups off the tees, doing nothing to stop it. Once the blues got there they then hid the tees.
We lost on the field. Two fielding errors that cost us at least two runs. More runs scored due to the lack of no back fence; but even with a fence those two runs would still have been scored. The other team was hitting well that day. We didn't get blown out even though we heard the opposing coach tell the team to beat us 20-0. It was two errors that cost us the game. It was a pretty well matched game, with each team getting on base; but we just couldn't get the big hits.
Our girls made their graduation in time and the rest of the team is finally on summer vacation having taken their last finals today.
As for karma, we did report it to CIF, but specifically told them it was not a formal protest and that we were not seeking a forfeit. Hope the coaches get a reprimand or at least some sort of punishment. So karma did come back to bite them, but not too hard.
