Dizzy Dean Baseball has chosen Camp Jordan in East Ridge to host the six-year-old and 11-year-old tournaments in 2010.
Kevin Wright, who heads the Camp Jordan baseball and softball program, said some 100 teams will take part.
He said it will mean a $3 million economic boost for East Ridge.
The last time East Ridge hosted a Dizzy Dean world series it brought in $1.5 million in local spending, he said.
Wright said one factor in landing the tournament was the fact that Camp Jordan has been outfitted with much-improved lighting.
He said the park will also host a softball tournament with 75-100 teams following the Dizzy Dean world series next summer.
