National Team Tracker

Interested in what our projected finish orders would mean for the five major international travel teams being selected this summer? We’ve got you covered, with this updating spreadsheet of national team rosters and selection priorities for all five meets.

Here’s how to read it: The colors refer to selection priorities, helping us re-order the sheet as we go to see which athletes will be selected first. We’ll use our projected finish orders to show who should make which team. Be patient, as this is a complex process that may require some time after previews go live to update our projected roster.

Selection criteria:

  • Blue: Priority #1
  • Red: Priority #2
  • Green: Priority #3
  • Yellow: Priority #4

We’ll update these as soon as we can after each new preview is posted. Remember that 2019 Worlds selections also include the results of 2018 Pan Pacs, which is why we’ll keep those roster spots in bold – they are tentative until Pan Pacs has wrapped, and all 2019 projected rosters are assuming that finish orders stay exactly as our Nationals finish predictions at Pan Pacs. Since our top 8 picks don’t often feature a lot of juniors, the Junior Pan Pacs roster projections will be pretty thin. We’ll be doing some extra coverage on the top Junior Pan Pac contenders next month.

Update: We’ve published a compilation of the top times by Junior Pan Pacs eligible swimmers over the Nationals qualifying period in every event. We’ll continue to add any junior athletes picked inside our top 8 to the Junior Pan Pacs roster below, but we’ll fill out the remainder with swimmers from those rankings to give an even better idea of Junior Pan Pacs roster spot predictions.

There is no World Championships this year. If you are predicting for next year, I don’t think Hagino will beat Kalisz in both IMs. And Sun won’t win the mile.


I don’t see watanabe winning 2 breast either he’s too much of a wild card


First day as a swim fan?




Yep and every dog has its day ……


Sun Yang WR in the 1500?


These predictions aren’t that bad they don’t need to be hated on !


Why are Caleb and MA in red in the 50 free on the last day?

(Couldn’t decide on 1breast or 2free)


You have Andrew over Cody Miller or Andrew Wilson? Yeah ok


Both of their best times are pretty much a full second faster than MA’s. Doesn’t make any sense.

How many kicks will they be allowed this year? Asking for a friend.


Caeleb will have more than 3 individuals, meaning he will have more than 3 first places 😉
