U.S. Olympic Swimming Trials are taking place June 13-20 in Omaha, Nebraska. Tuesday's finals session can be seen live on NBC at 8 p.m. ET, as well as streamed on NBCOlympics.com [HERE] and the NBC Sports App.

Four consecutive finals highlight Night 3 at the United States Olympic Swimming Trials, where a handful of defending Olympic gold medalists and rising superstars will attempt to lock in their places on the Tokyo team.

Kieran Smith, already Tokyo-bound in the men’s 400m freestyle, can become the first American swimmer to double-qualify for this summer’s Olympics with a strong performance in the men’s 200m freestyle.

Tuesday night’s second final could bring the fireworks. The women’s 100m backstroke features three of the five fastest athletes in the event since the start of 2021. University of Alabama senior Rhyan White and winner of this event at 2016 Trials, Olivia Smoliga, are both in the hunt for an Olympic spot, but neither are likely to out-touch Regan Smith. The 19-year-old phenom will be on world record watch Tuesday, after hers from the 2019 World Championships was eclipsed over the weekend by Australian Kaylee McKeown.

The men take their turn at the 100 back in the night’s third final. Rio 2016 gold medalist Ryan Murphy leads a field that also includes the London 2012 Olympic champion, 36-year-old Matt Grevers.

And in the women’s 100m breaststroke, Lilly King looks to make things official in the event she’s dominated for half a decade, while 2019 Pan American Games champion Annie Lazor and 17-year-old Alaska native Lydia Jacoby aim for their first Olympic Games appearances. 

The evening session also features Katie Ledecky in the semifinal of the women's 200m freestyle, along with semifinals in the men's 200m butterfly and women's 200m individual medley.

Follow along here for up-to-the-minute highlights and results as the action unfolds.

Katie Ledecky is well on her way to qualifying in her second event for the Tokyo Olympics. The defending gold medalist in the event led all semifinalists with a time of 1:55.83 to advance as the top seed in Wednesday’s 200m free semifinal.

It sets up a uniquely busy night for Ledecky, who will also swim the final of the 1500m freestyle on Wednesday after advancing from this morning’s prelims.

Former NCAA champion Paige Madden, who contracted the COVID-19 virus in the spring and is still battling lasting effects, finished second to Ledecky in Heat 1 and will swim beside her in the final as the second seed.

London 2012 gold medalist Allison Schmidt won the second semifinal with a time of 1:57.53, putting her in fourth going into the final.

1. Katie Ledecky - 1:55.83

Kieran Smith is USA Swimming’s first two-time qualifier for this summer’s Tokyo Olympics.

After winning Sunday night’s final of the 400m freestyle – and, importantly, hitting the Olympic time standard in the event – Smith touched first in the 200m free to book his second event in Tokyo.

And he will be part of a third. The Florida Gator will compete for the U.S. in the men’s 4x200m freestyle relay in Tokyo, alongside the man who finished second in Tuesday’s final, Townley Haas.

The Rio 2016 gold medalist earned the second and final individual spot for the event in Tokyo with a time of 1:45.66. Drew Kibler and Andrew Seliskar just missed out on the individual places but will represent the U.S. alongside Smith and Haas on the U.S. relay team.

RESULTS:

1. Kieran Smith - 1:45.29

2. Townley Haas - 1:45.66

3. Drew Kibler - 1:45.92

4. Andrew Seliskar - 1:46.34

5. Zach Apple - 1:46.45

6. Patrick Callan - 1:46.49

7. Blake Peironi - 1:46.57

8. Carson Foster - 1:46.67

When Regan Smith set a then-world record at the 2019 World Championships, she said after that nothing hurt.

That wasn’t the case Tuesday, but the 19-year-old phenom confirmed her spot at her first Olympics anyway, finishing first in the final of the 100m backstroke in 58.35.

“It started to hurt really bad,” Smith said after the race. “I could see girls on both sides of me and I just knew I had to get my hand on that wall as fast as I could.”

University of Alabama’s Rhyan White claimed the other probable Olympic position with a time of 58.60.

2016 Olympian Olivia Smoliga just missed Tokyo qualification.

RESULTS:

1. Regan Smith - 58.35

2. Rhyan White - 58.60

3. Olivia Smoliga - 58.72

4. Katharine Berkoff - 58.82

5. Isabelle Stadden - 59.37

6. Phoebe Bacon - 59.58

7. Catie DeLoof - 59.87

8. Lisa Bratton - 1:00.24

Ryan Murphy is off to Tokyo to defend his Rio 100m backstroke gold.

The Ponte Vedra Beach, Florida, native finished first in Tuesday’s final with a time of 52.33.

He turned at the 50-meter mark under world record pace but was put under pressure in the final 15 meters by the unheralded Ohio State Buckeye Hunter Armstrong, who claimed a second place finish and a potential trip to Tokyo.

Matt Grevers, the 36-year-old London 2012 gold medalist, finished eight-tenths shy of another Olympics appearance.

RESULTS:

1. Ryan Murphy - 52.33

2. Hunter Armstrong - 52.48

3. Shaine Casas - 52.76

4. Bryce Mefford - 52.91

5. Justin Ress - 53.00

6. Matt Grevers - 53.27

7. Hunter Tapp - 53.45

8. Michael Andrew - 53.59

Lilly King handled business and Lydia Jacoby made her mark in the final of the women’s 100m breaststroke.

King is headed to her second Olympic Games in her signature event. The 24-year-old Indiana native outpaced the field in the women’s 100 breast, finishing in a time of 1:04.79. She’ll hope to defend her Rio 2016 gold medal in Tokyo.

That was expected. Jacoby setting the second-fastest mark in the world of 2021 at 1:05.28, was not. The 17-year old accomplished the feat and likely punched her ticket to Tokyo despite King’s attempts at throwing her off track, something King is always known to try.

“I kinda tried to mess with her in the ready room but she wasn’t having it,” King half-joked.

Jacoby is all but guaranteed to become the first Olympic swimmer in history from the state of Alaska.

Annie Lazor, the second-fastest in Monday’s semifinals, missed out on the Olympic positions by 0.32.

RESULTS:

1. Lilly King - 1:04.79

2. Lydia Jacoby - 1:05.28

3. Annie Lazor - 1:05.60

4. Bethany Galat - 1:05.75

5. Kaitlyn Dobler - 1:06.29

6. Micah Sumrall - 1:06.84

7. Molly Hannis - 1:07.26

8. Emily Escobedo - 1:07.31

9. Miranda Tucker - 1:07.44

A tie for the top time across both semifinals of the men’s 200m butterfly sets up an intriguing Wednesday night final.

Nineteen-year-old Luca Urlando, a University of Georgia swimmer, set a mark of 1:55.21 in Heat 1, which World Championships veteran Zach Harting matched in Heat 2.

Trenton Julian took the third seed at 1:55.35. Julian led Heat 2 at the 150m mark, but Harting closed a gap of over two seconds in the final lap to earn a center lane in the final.

Tom Shields, a 2016 Olympian in the event alongside Michael Phelps, did not advance out of the semifinals.

ADVANCED TO FINAL

~1. Luca Urlando - 1:55.21

~1. Zach Harting - 1:55.21

3. Trenton Julian - 1:55.35

4. Gunnar Bentz - 1:55.42

5. Nicolas Albiero - 1:56.29

Fresh faces abound among the eight swimmers advancing to Wednesday’s women’s 200m IM final. Of the group, only Melanie Margalis, who advanced with the fifth-best time, is a veteran of an Olympic Games.

A pair of 19-year-olds will hold the center lanes in the final thanks to their performances in the semifinals. Alex Walsh, the defending Pan American Games champion in the event, posted the top time at 2:08.87. Kate Douglass followed suit at 2:09.99.

ADVANCED TO FINAL:

1. Alex Walsh - 2:08.87

2. Kate Douglass - 2:09.99

3. Meghan Small - 2:10.09

4. Madisyn Cox - 2:10.22

5. Melanie Margalis - 2:11.25

6. Torri Huske - 2:11.42

7. Emma Barksdale - 2:11.52

8. Beata Nelson - 2:11.55

After all scheduled event concluded, Jake Mitchell stepped up to the blocks solo. Mitchell, who finished second in the 400m freestyle final Sunday night but did not meet the Olympic time standard to qualify, was given an opportunity to rectify that in a time trial.

He did not waste the chance. Mitchell broke the standard of 3:46.78 by less than a second.

He finished in 3:45.86 to a huge ovation from the crowd, all but guaranteeing he will join Kieran Smith in the 400 free competition in Tokyo.
