Tom Shields claimed the second spot on the U.S. team by touching next in 51.19. Shields was an Olympian in 2016, taking gold as part of the 4×100 medley relay.
Dressel, who had already made the Olympic team with a victory in the 100 freestyle, made it 2-for-2 on the night when he returned a short time later to win his heat in the semifinals of the 50 free.
Dressel is hoping to swim three individuals events in Tokyo and perhaps all four relays, giving him a shot at joining Michael Phelps, Mark Spitz and Matt Biondi as the only swimmers to win seven swimming medals at the Olympics.
At the last world championships, Dressel became only the second swimmer after Phelps to win eight medals at a major international competition. The 24-year-old Floridian claimed six golds and two silvers, though two of those were in non-Olympic events.
He said there’s room for improvement in the 100 fly.
“I was a little too excited coming home,” he said. “I was a little sloppy at the end.”
With Phelps now retired, the burden is on Dressel and Ledecky to step up at these pandemic-delayed Olympics.
Grimes wasn’t the night’s only surprise. Regan Smith, who has already won the 100 back, faded to third in the 200 back to miss out on a second individual event in Tokyo.
Rhyan White took the victory in 2:05.73, with 18-year-old Phoebe Bacon claiming the second spot in 2:06.46.
Smith finished third in 2:06.79, more than 3 seconds off her personal best.
White and Bacon are both headed to the Olympics for the first time.
Two Olympic veterans bounced back from disappointing performances to keep their Tokyo hopes alive.
Simone Manuel, who revealed that she was diagnosed with overtraining syndrome after failing to advance from the semifinals of the 100 free, moved on to the final of the 50 free with the third-fastest time (24.50).
“I’m just trying to race as best as I possibly can with whatever my body has,” Manuel said. “I’m a person that fights to the end. I’ll never know what the 50 is going to be if I don’t go out there and give it a try.”
Nathan Adrian is facing the same predicament in the men’s 50 free after failing to qualify in the 100.
The eight-time Olympic medalist was third-fastest in the semifinals at 21.78, trailing only Dressel (21.51) and Michael Andrew (21.55).
Adrian must finish in the top two in Sunday final to make his fourth Olympic team.
The first Black woman to win an individual gold medal in swimming, Manuel won’t get a chance to defend her historic title in the 100. But revealing her health and mental struggles relieved some of the pressure she was feeling coming into the trials.
“I’ve gotten a lot of nice messages and responses from people,” Manuel said. “It makes me think that I’m not alone.”
She added, “I just want to see whatever I’ve got. I want to walk away with my head held high after this meet.”
Abbey Weitzeil was fastest in the women’s 50 free, posting a personal best of 24.27 to take the top seed into the final. She already won the 100 free at these trials.
“I’m super excited. I haven’t done a best time since 2015,” the 24-year-old Californian said. “I was really shocked when I saw the screen, but I can’t let my guard down.”
