World record holder Lilly King became the first woman to qualify outright for a U.S. Olympic team in the 100m breast in back-to-back Games since Tracy Caulkins in 1980 and 1984 with win Tuesday night in Omaha at the U.S. Olympic Swimming Trials. 

King, 24, went 1:04.79, still a ways off of her own world record of 1:04.13. Teenager Lydia Jacoby finished second in 1:05.28, likely also qualifying for Tokyo -- and becoming the first swimmer from Alaska to make a U.S. Olympic Swim Team. King's teammate Annie Lazor was third in 1:05.60.

"[Jacoby's] awesome. We swim completely different races, but I tried to mess with her a little bit in the ready room and she wasn't having it, so I respect that," King told NBC's Michele Tafoya.

Although the Rio Olympics were her first major international meet, King quickly embraced the spotlight and became a fan favorite for her outside-the-pool antics. Her "finger-wagging" at an image of Russian rival Yuliya Efimova went viral, and King later called out Efimova for having served a doping ban.

King remains one of the more outspoken athletes in the world when it comes to cheating. Ahead of Trials, she expressed concern that some countries may have taken advantage of a decrease in drug testing during the COVID-19 pandemic.

The Indiana native is set to race in the 200-meter breaststroke later this week, where she owns the No. 5 time in the world this year.
