It was an exciting four days of competition at the 2022 U.S. Open Championships in Greensboro, NC. From World Junior records, meet records, and National Age Group records, there were seven different major records broken. Four of those record-breaking swims belong to Regan Smith and Chase KaliszThat’s notable because this was both of their first major meets in ASU caps; earlier this year, they moved their training bases to join Bob Bowman‘s pro group.

The calendars changed to December in the middle of the meet but it was still Summer time in Greensboro, as 16-year-old Summer McIntosh continued to impress, throwing down a blistering 4:28.61 in the 400 IM. That swim marks new World Junior, Commonwealth, Americas, and U.S. Open records as well as makes her the #3 all-time performer. The butterfly leg of her swim is particularly impressive–she split 59.40, which would have finished fourth in the individual 100 fly.

You can watch these record-breaking races and more below.

Katie Ledecky Out-Touches Summer McIntosh in 400 Free for New U.S. Open Meet Record

The rematch between Katie Ledecky and McIntosh lived up to the hype. After McIntosh out-touched her by .08 at the Toronto stop of the FINA World Cup, Ledecky got her revenge, winning by that same margin in Greensboro. Both swimmers dipped under 4:00, with Ledecky resetting her own championship record, which she had set in 2021.

Many were expecting a tight race between veteran Chase Kalisz and teenager Baylor Nelson, but Kalisz earned this win decisively, finishing 2.62 seconds ahead of the field for a new championship record. Kalisz owned the old record as well, which he’d set in 2019.

Coming out of prelims, it was clear that this was McIntosh’s race to lose. Not only did she win by a huge margin, she swam a sizzling 4:28.61. That swim is the fourth fastest performance all-time, and makes her the third fastest performer in history. It also rebreaks her world junior record which she set in summer 2022, and earns her Commonwealth, Americas, and U.S. Open records.

Chase Kalisz Sets Second U.S. Open Meet Record in Two Days


  • World Record: 4:03.84 – Michael Phelps, USA (2008)

  3. Landon Driggers (TENN) – 4:20.85

Following McIntosh’s swim, Kalisz continued his winning and record-breaking ways by setting another championship record in the 400 IM. There were rumors this summer that Kalisz was done with the 400 IM and wanted to focus on other events, but he clearly isn’t done with it quite yet.

His swim breaks Sebastien Rosseau‘s record in 4:11.11, which had stood for nine years.

When asked after the race what her results were showing her, Smith responded that it showed her that she made the right decision moving to train with Bob Bowman and the ASU pro group.

Chase shows it how it is done in IM! As he said after both races, it goes best if you have the best IM coach! ASU’s Bob Bowman! Who, for you young swimmers, was also Michael Phelps coach and is also currently Leon Marchan’s coach! One coach two of the top current IM swimmers and Michael Phelps!
