This is probably a dumb question but I could not find any info on how many teams from each region advance to USTA team national championships. Is it just the team that won each section or do larger sections get more than 1 team (TX, Socal etc)?
There are some cases, typically at the 5.0 level, where enough sections don't send a team that a wildcard or two may be given out to try to fill the flights. I think they always tried to have 15 teams in the past (there are 17 sections) so they had either:
17 teams - Four flights of 5, 4, 4, 4
16 teams- Four flights of 4
15 teams - Three flights of 5 with one wildcard from the 2nd place teams advancing to the semis
Now, with the new flightless Nationals format, there is no longer a need to have 15, 16, or 17 teams, so perhaps the days of this rare wildcard are gone.
