Michael Phelps has company. Caeleb Dressel won his seventh gold medal of the world championships on Sunday, putting the US team ahead to stay with another dominating swim in the 4x100m medley relay.

A day after becoming the first swimmer to win three golds in one night at a major international meet, Dressel joined Phelps in another elite club with seven golds at swimming’s second-biggest competition after the Olympics.

Phelps had seven victories at the 2007 worlds — a prelude to his unprecedented eight golds the following year at the Beijing Olympics, although Phelps competed in an era before mixed gender relays.

Dressel matched the feat along the banks of the Danube, looking like America’s next great swimming star. The 20-year-old University of Florida student won three individual golds and was part of four winning relay teams.

It was a big night all around for the Americans.

Lilly King took her breaststroke rubber match with Yulia Efimova — and set another world record for good measure. The brash King knocked off her second record of the world championships, touching first in the 50m breaststroke Sunday. King eclipsed the mark of 29.48sec set by Lithuania’s Ruta Mielutyte at the 2013 worlds in Barcelona.

King added the 50m mark to her record-setting performance in the 100m breaststroke. This was essentially the deciding match of her duel with Efimova, who won the 200m breaststroke while King finished fourth. Efiomova settled for silver in the 50m at 29.57, while another American, Katie Meili, took the bronze in 29.99.

“I always think Lilly has a world record in her,” Meili said. “Yeah, I knew she was going to go really fast. She’s been incredible this meet. Totally lights on her every time she gets in the pool, so I’m very very proud of her.”

Despite hard feelings between King and Efimova, sparked last summer when King griped that the Russian should not be allowed to compete because of doping violations, the two hugged each other and even appeared to joke around a bit after the race.

Chase Kalisz completed a sweep of the individual medleys to carry on the tradition of the American dominance, even after Phelps’ retirement and Ryan Lochte not being allowed to compete in Budapest because of his shenanigans at the Rio Olympics. Kalisz romped to victory in the 400m medley on the heels of his victory in the 200m IM.

The US finished with 18 golds and 38 medals overall — a huge improvement over the previous worlds two years ago in Kazan, where the Americans managed just eight golds and 23 medals.

There was success for the US in men’s diving too, where Steve LoBue capitalized on a mistake from Gary Hunt in the last round to win gold. Diving from a 27m platform into a temporary pool on the Danube river, Hunt was leading going into the fourth round, but the British diver over-rotated his entry. He picked up only 70 points and finished fifth.

“I definitively felt the pressure. My last dive is relatively new for me, and after four competitions in four weeks, I felt my legs shaking a bit. I had enough power on top of the board, but I had to fight with the G-force in my legs,” Hunt said.

LoBue had made no mistake, earning a round-best 113.40 points for a total of 397.15. “It’s a surreal moment. Hundreds of hours of your life come together in three seconds. I couldn’t be happier,” the American said. “It takes a very special person to jump from 27m. We do help each other a lot, as we all understand and respect the fear.”

LoBue has good reason to — in May 2015 he struck his head on the platform during a diving meet in La Rochelle, France. “Some other people would have resigned or succumb to the fear, but I competed two weeks later and I realized that it was a sort of freak accident. You have to overcome your fear,” LoBue said. “After that, I changed my program to include more somersaults instead of twists.”
