Their are a bunch of great umpires in this SC state. Fortunately our team gets them, so it is very hard to comment on what 3A is getting. But the bottom line is, since it is a double elimination tourney, calls will go your way sometimes and against you sometimes.
Unless there is a clear and definitive argument for BIAS, your team simply has to rise above and win. If a softball game comes down to one "bad" call, then your team did not do enough to win.
Again, this poster is the wrong to ask, for from my perspective the umpiring I have seen has been the best in SC, and in the Nation.
If you want to see "homer" umpiring, just go to TN and play a tourney like we did this year. The one (1) loss (out of 2 L's) Boiling Springs had happened in TN, against a top team. I am convinced it was a completely rigged game, much like a wrestling match. We took our lumps, walked away proud, and went home to our much preferred state of SC.
And did not really complain about it, except on this post a month later.
