Night 2 of the 2024 U.S. Olympic Swimming Team Trials presented by Lilly featured the crowning of a pair of first-time Olympic team members, as well as the triumph of a savvy veteran.

Gretchen Walsh opened Trials with a bang on Night 1 when she broke the world record in the women's 100m butterfly. However, she still had to navigate a stacked final that included Torri Huske and Regan Smith to clinch her place in Paris.

In the men's 400m IM, Carson Foster felt a wave of emotion after making his Olympic dream a reality, beating the defending gold and silver medalists in the process to do so.

Experience proved to be the key in the men's 100m breaststroke, where 30-year-old Nic Fink emerged from a close final to lock in his second Olympic appearance on a night that saw plenty of star power elsewhere in the pool, from Katie Ledecky to Ryan Murphy to Simone Manuel.

See below for event-by-event results, recaps and highlights.

Cincinnati, Ohio's Carson Foster barely missed out on a trip to the Tokyo Olympics when he finished third in the men's 400m IM at the 2021 Trials. This time, the Texas Longhorn would not be denied his ticket to the Games.

Foster finished in 4:07.64 to win the first final of Night 2, beating out the two men that bested him (and went on to finish 1-2 in Tokyo) last time. 

Tokyo gold medalist Chase Kalisz touched second behind Foster, and will almost certainly get a chance to defend his Olympic title in Paris.

Jay Litherland, the silver medalist in Tokyo, managed a third-place finish this time.

FINAL RESULTS:
1) *Carson Foster | 4:07.64
2) **Chase Kalisz | 4:09.39
3) Jay Litherland | 4:12.34
4) Ian Grum | 4:15.06

After breaking the world record in the semifinals, Gretchen Walsh backed up her history-making swim with another special performance to cement her status as a force to be reckoned with in Paris.

Walsh punched her ticket to the 2024 Olympics with a time of 55.31, just 0.13 off her record pace from 24 hours prior. She now holds the top-two times in history in the event.

"Making the team was the biggest goal, but setting a world record was absolute insanity," Walsh said of her breakout weekend.

Torri Huske, the swimmer thought to be the favorite coming into Trials, likely secured her place in Paris by edging out friend and fellow U.S. star Regan Smith. Smith will be the favorite in the 200m butterfly, as well as in the backstroke events, where she is often at her best.

FINAL RESULTS:
1) *Gretchen Walsh | 55.31
2) **Torri Huske | 55.52
3) Regan Smith | 55.62
4) Claire Curzan | 57.47
5) Kelly Pash | 57.72
6) Beata Nelson | 57.80
7) Lillie Nordmann | 57.92
8) Emma Sticklen | 58.44

The stage is set for an uber-tight final after three swimmers finished within a half-second of each other across the two men's 200m freestyle semifinals.

Tokyo 400m free bronze medalist Kieran Smith set the pace at 1:45.39, with both Luke Hobson and Drew Kibler close behind.

A half-dozen men could secure their spots on the Olympic team in Monday night's final. As many as six swimmers could be chosen to compete on the U.S. 4x200m freestyle relay team in Paris.

Both Aaron Shackell and Daniel Diehl finished in a tie for eighth with identical times of 1:47.00. In an exciting swim-off later in the evening, Shackell chased down Diehl to win the last lane by 0.21.

ADVANCING TO FINAL:
1) Kieran Smith | 1:45.39
2) Luke Hobson | 1:45.58 
3) Drew Kibler | 1:45.82
4) Jake Mitchell | 1:46.43
5) Blake Pieroni | 1:46.52
6) Brooks Curry | 1:46.60 
7) Chris Guiliano | 1:46.83
8) Aaron Shackell | 1:47.00

In front of a home crowd, Indiana native and 2016 Olympic gold medalist Lilly King showed why she's still among the best in the world in the 100m breaststroke. King posted the top time of the semifinal stage by nearly a full second, and looks to be the clear favorite for Monday night's final.

The battle for the presumptive second Olympic slot, however, appears to be wide open.

In the first semifinal, University of Virginia junior Emma Weber upset reigning Olympic gold medalist Lydia Jacoby, who advanced as the fourth-seeded swimmer.

Oregon native Kaitlyn Dobler finished closest to King's time in 1:06.42.

ADVANCING TO FINAL:
1) Lilly King | 1:05.57
2) Kaitlyn Dobler | 1:06.42
3) Emma Weber | 1:06.48
4) Lydia Jacoby | 1:06.66
5) Kaelyn Gridley | 1:06.67
6) Alex Walsh | 1:06.87 
7) Ella Nelson | 1:07.41
8) McKenzie Siroky | 1:07.73

Olympic gold medalist and 2024 world champion Hunter Armstrong narrowly avoided disaster in the second semifinal when he slipped at the start.

Armstrong found himself in a massive early deficit, in last place at the 50-meter mark. But the 23-year-old kept his foot on the gas pedal and recovered to finish second in the heat and crucially earn himself a spot in Monday's final.

There, he'll meet four-time Olympic gold medalist Ryan Murphy, who paced the field at 52.65 seconds in the first semi.

ADVANCING TO FINAL:
1) Ryan Murphy | 52.65
2) Adam Chaney | 53.08
3) Jack Aikins | 53.23
4) Hunter Armstrong | 53.57
5) Tommy Janton | 53.61
6) Jack Wilkening | 53.70
7) Justin Ress | 53.78
8) Will Modglin | 53.83

Nic Fink, 30, who balances his swimming career while working full-time as an engineer, will become a two-time Olympian this summer.

Fink, the 2024 world champion, won an extremely tight 100m breaststroke final in 59.08 seconds. The New Jersey native represented Team USA in Tokyo in the 200m breaststroke.

Charlie Swanson finished less than a tenth behind Fink to likely become a first-time Olympian.

FINAL RESULTS:
1) *Nic Fink | 59.08
2) **Charlie Swanson | 59.16
3) Josh Matheny | 59.23
4) Liam Bell | 59.40
5) Noah Nichols | 59.69
6) Jake Foster | 59.84
7) Luke Rodarte | 59.85

Katie Ledecky won the second women's 200m freestyle semifinal to earn a middle lane for the final in an event she may not elect to race in Paris, should she qualify. However, Ledecky is well on her way to earning a spot on the U.S. 4x200m relay team, where she has excelled in her career.

Paige Madden touched first in the first semifinal, which also featured two-time Olympic gold medalist Simone Manuel. Manuel finished with the eighth-best time, just good enough to secure a lane in the final.

ADVANCING TO FINAL:
1) Katie Ledecky | 1:55.25
2) Claire Weinstein | 1:55.86
3) Paige Madden | 1:56.36
4) Erin Gemmell | 1:56.53
5) Katie Grimes | 1:57.19
6) Alex Shackell | 1:57.42
7) Anna Peplowski | 1:57.55
