U.S. Olympic Swimming Trials are taking place June 13-20 in Omaha, Nebraska. Saturday's finals session can be seen live on NBC at 9 p.m. ET, as well as streamed on NBCOlympics.com [HERE] and the NBC Sports App.

The two brightest stars in the sport of swimming look to qualify in their signature events Saturday night at the U.S. Olympic Swimming Trials.

Caeleb Dressel leads off Night 7 with the final of the men’s 100m butterfly, the event in which he holds the world record at 49.50. He challenged that mark in Friday’s semifinal, coming up just 0.26 seconds short.

Perhaps Dressel will have an extra gear in the final, though he’ll need to conserve some energy for the semifinals of the 50m free taking place later in the session. Dressel clocked the top time in the prelims at 21.29.

Meanwhile, to say Katie Ledecky is a safe bet to qualify for her fourth individual event in the women’s 800m freestyle is an understatement. Ledecky owns the 23 fastest women’s 800 times in history and is the two-time defending Olympic champion in the event. Prior to her four-gold medal performance in Rio, a 15-year-old Ledecky won the 800 at the 2012 London Olympics, her first international meet.

Ledecky has already qualified in the 200, 400 and 1500m freestyle events. A top-two finish in the 800 would set her up for an unprecedent distance sweep in Tokyo, where the women’s 1500 will make its Olympic debut.

Elsewhere, Regan Smith is a favorite to add the 200m backstroke to her Olympic schedule which already includes the 100 back and the 200 fly.

Finally, two swimming icons will attempt to keep their Tokyo hopes alive in the semifinals of the men’s and women’s 50 free. Neither eight-time Olympic medalist Nathan Adrian nor four-time medalist Simone Manuel qualified for the final of their respective 100m freestyle events, but both can do so in the splash-and-dash semifinals Saturday.

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

The race really was between Caeleb Dressel and Caeleb Dressel (of two years ago).

The world record holder was ahead of his own 2019 World Championships pace through 75 meters but ultimately touched in 49.87, just 0.37 off the record.

With the record-setting win, Dressel clinched qualification in his second individual event for the Tokyo Olympics where seven gold medals could be at play. He hopes to round out individual qualification in the 50m freestyle this weekend, then could compete on as many as four relay teams this summer.

Tom Shields, who finished second in the 100 fly at the 2016 edition of Trials, repeated the feat in 51.19 to qualify for his second Olympics.
