In the last two nights, Chase Kalisz set a personal best in the 200m breaststroke and posted the fastest time in the world this year in the 400m individual medley in Atlanta.
Kalisz, the Olympic 400m IM silver medalist, is setting up well for the U.S. Championships next month and the world championships in Budapest in July.
On Friday, Kalisz won the 200m breast in 2:10.74, lowering his personal best in the event at a second straight meet. Kalisz came into the year with a 200m breast best of 2:12.43 from 2014.
Kalisz rarely races the 200m breast and might not contest it at nationals, where the top two per event qualify for worlds. Kalisz now ranks third in the U.S. in the 200m breast this year.
“My endurance is kind of getting back to where I want to be,” Kalisz, coming off his senior season at the University of Georgia, told media Friday night. “Last year, I was consistent almost every single day, and I’m finally back to that level.”
Kalisz came back Saturday and won the 400m IM in 4:09.43, the best time in the world this year by .58 of a second. The 400m IM is his signature event. Kalisz is looking to duel Japan’s Kosuke Hagino and Daiya Seto, the Olympic gold and bronze medalists, and Hungarian Dávid Verrasztó at worlds.
Kalisz’s time Saturday was his fastest-ever outside of a major international meet or a U.S. Championships by 1.58 seconds.
Also Saturday, Katie Ledecky won for the second straight night.
The four-time Rio Olympic champion took the 200m freestyle in 1:56.26 after dominating the 400m free on Friday.
Ledecky was 1.44 seconds slower in the 200m free than at this same meet last year but also said she was “racing a little bit tired” due to recent hard training. She ranks No. 4 in the world in the 200m free this year, while leading the 400m and 800m free rankings.
Simone Manuel, the co-Olympic 100m free champion, followed her 100m free win from Friday by taking the 50m free on Saturday. Manuel clocked 24.73 seconds, not her best time this year, but still broke the pool record set by Amy Van Dyken at the 1996 Olympics.
Ryan Murphy, who swept the backstrokes in Rio, won the 200m back Saturday in 1:55.82, dousing Rio Olympic finalists Jacob Pebley (1:56.43) and Ryosuke Irie (1:57.85). Murphy ranks third in the world in the 200m back this year.
The meet concludes Sunday, with finals streamed on NBCSports.com/live and the NBC Sports app from 7-8:30 p.m. ET.
