Chase Kalisz leads a host of Olympic medalists and world champions at a USA Swimming Pro Series meet in Atlanta starting Thursday and airing live on NBCSN, NBCSports.com/live and the NBC Sports app.
The meet is the second of six in the Pro Series leading to the U.S. Championships in Irvine, Calif., in late July.
The U.S. Championships are generally a qualifier for this year’s major international meet — the Pan Pacific Championships in Tokyo in August — though USA Swimming hasn’t confirmed that for this season yet. Nationals and Pan Pacs also usually serve as the two qualifiers for the 2019 World Championships in South Korea, the biggest meet between now and the 2020 Olympics.
