When I coached 13u it was my first year of travel only baseball. Before that travel was providing potential LL all stars better weekly competition. We were invited to fourteen 13u "World Series." We were a highly regarded team in the region. Then I found out anyone and everyone was invited to the same tournaments.
The only relevant World Series are the ones a team needs to qualify to attend. In USSSA there was a regional tournament to win to qualify for Orlando. At 13u we finished third in the region. It was enjoyable to beat teams who traveled to our region after losing in theirs. None of these teams finished in the top five in ours.
