How do you explain this to an 11 year old?

I am one of those people that firmly believes there is no shame in losing if you give a solid effort and do your best. Of curse we all like to win. I also believe you should never blame the officials for a loss. There is always an error, a strike out, a missed shot or dropped pass that could have made a difference.

Last night our 11 year old all star team finished second in the state baseball tourney. They lost because there was a totally incompetent umpire. He missed four key Calls that cost us two runs. We lost by one run. Even the opposing coach turned around and said "oh my God, that is unbelievable" after one of the calls. When your competitor thinks you are getting screwed, it must be bad.

This guy was horrible for the entire tournament, coaches from every team were complaining about his terrible calls. How do you explain to an 11 year old, that knows he was cheated, that it is OK, he played his best? We will get them next year rings a little hollow when the season is ended not by a better team, but by an umpire.
