Simulating 2026 USTA League Nationals - 18 & Over 3.0 Men

It is that time of year!  The first USTA League Nationals for 2026 begins this weekend, and with that, it is time to publish the summaries of my simulations.

This weekend was supposed to have five events, but with the possible hurricane hitting the Gulf coast causing a postponement of all the events scheduled for Mobile this weekend, we have just the 18 & Over 3.0 in Orlando and 18 & Over 3.5 in Surprise.

I've been doing simulations since 2018 and have found that the four semi-finalists are usually in the top six to seven projected teams, and more often than you might think, I project the four semi-finalists perfectly.  There are surprises sometimes and a mid-pack team overachieves and advances, that is why the matches are played on the courts and not on a computer.  Still, it is interesting to do these simulations and see how the projections do.

Why do these simulations you ask?  The primary reason is that the format for USTA League Nationals is now a flight-less random round-robin where each team plays four other random opponents.  This introduces significant variations in schedule strength, the possibility of an undefeated team not making the top-4, and teams vying for the top-4 perhaps not having played head-to-head and unfortunate tie-breakers being used.  The simulations aim to educate folks on how it all works and look at what may happen.  Also see this write-up for some things to know about Nationals.

Like I've done in recent years, I'll be primarily just giving the data from the simulation and not writing a bunch of words.  Most of it is self-explanatory, but the favorites and contenders will be listed in alphabetical order.  The strengths are based on played averages.  Contact me if you want to learn more.

I've done the 18 & Over 3.5 men and women, and 3.0 women, now the 3.0 men that had a late change with Intermountain no longer on the schedule.

Teams: 15

Chance of 3 undefeated: 19%
Chance of 4 undefeated: 2.7%
Chance of 5 undefeated: <1%

Chance of tie for last spot / most likely size: 73% / 4

Strongest / weakest team strength: 3.23 / 2.99
Toughest / easiest schedule: 3.16 / 3.04
Favorites: Caribbean, Midwest, NorCal, Texas
Contenders: Southwest

Have a chance: SoCal

Record to make semis: 3-1 / 12-8

Two teams are far and away favorites, with two more joining them to meet the criteria.  Just one contender and barely another that has a chance.  This looks pretty top-heavy.

There should be two 4-0 teams with a good chance of three, but perhaps not four.

What do you think?
