Don't They Have the Mercy Rule in this Little League?

A friend of SportsProf e-mailed to say that if SportsProf was short on content, he should report that this software executive coached his kids' second-grade Little League team to a 26-3 win last night (in the Dallas area). Which led to a question: don't they have the mercy rule, so that if you're up by more than 10 runs after 5 innings, they call the game? I posed this to a colleague of mine who's a native of the Midwest, who replied, "They don't have the mercy rule down there. It's Texas."
