The U.S. Swimming Championships are in two weeks, and it’s arguably the second-most important domestic meet of the Olympic cycle.
Nationals will not only determine the team for the year’s major international meet — August’s Pan Pacific Championships — but also partially determine the team for the 2019 World Championships. The selection procedures all but assure the top two per individual event at nationals make Pan Pacs with third-place finishers also strongly in the running. Heck, some fourth-place finishers made the 2014 Pan Pacs team.
The 2019 Worlds team is made up by best times between nationals and Pan Pacs (top two per individual event).
