Watch: Daniel Diehl Lowers 17-18 NAG Record from Prelims with 53.07 100 Back in Final

2022 U.S. OPEN SWIMMING CHAMPIONSHIPS

FRIDAY FINALS HEAT SHEET

Daniel Diehl lowered his own boys’ 17-18 NAG record from prelims in the men’s 100-meter backstroke final on Friday night, clocking a 53.07 to shave .04 seconds off his mark from this morning. 

MEN’S 100 BACKSTROKE – FINAL

  • World Record: 51.60 – Thomas Ceccon, ITA (2022)
  • American Record: 51.85 – Ryan Murphy (2016)
  • U.S. Open Meet Record: 52.51 – Nick Thoman, USA (2009)
  • U.S. Open Record: 51.94 – Aaron Piersol, USA (2009)
  • 2024 Olympic Trials Cut: 55.69

PODIUM:

  1. Daniel Diehl (CUY) – 53.07
  2. Evangelos Makrygiannis (UN) – 54.41
  3. Tommy Janton (ND) – 54.96

Diehl won the race by over a second ahead of Evangelos Makrygiannis. Notre Dame’s Tommy Janton touched third, only .06 seconds off the lifetime best he swam at YMCA Nationals in July 2022.

Diehl, who recently turned 17 in October, was out a bit slower than he was in prelims, turning in 26.00 before coming home in a blazing 27.07. His swim this morning broke a nine-year-old NAG record set by Ryan Murphy in 2013 (53.38), but that mark lasted less than a day.

Split Comparison

Diehl, Junior Pan Pac prelims Diehl, Junior Pan Pac final Diehl, U.S. Open prelims Diehl, U.S. Open final
25.69 25.57 25.87 26.00
53.40 (27.71) 53.27 (27.70) 53.11 (27.24) 53.07 (27.07)

When asked after the race about his goals for the next year, Diehl said he has sights set on the world junior record of 52.53 belonging to Russia’s Kliment Kolesnikov.

“52.53 — that’s the world junior record. That’s what I’m looking for,” Diehl said.

“This was the focus meet for a while,” he added. “I’m just excited to be here.”

Diehl also posted a personal best in the 200 IM on Thursday night when he clocked the first sub-2:00 time of his life and placed third with a 1:59.89. He’ll have a chance for another personal best on Saturday in the 200 back. 

In the boys’ 17-18 NAG rankings for the 100 back, Diehl now stands more than three-tenths of a second clear of any other swimmer ever.

After placing 31st in the 100 back at the 2021 U.S. Olympic Trials at the age of 15, Diehl has made a massive leap over the last year and a half. After his 15-16 NAG record swim in March, he finished eighth in the 100 back at the International Team Trials in April, and then won the event at the Junior Pan Pacs in August while adding three more gold medals on the American relays.

Gunner grant is not a name I would have remembered for top 5 LCM 100 bk at that age. I looked him up. He’s a junior at Harvard now. 46.3/1:41.2. 53.8/1:59.9 lcm. Didn’t even make ncaas last year since Dean was their backstroker on relays. Now I know…

Glory days

Unfortunately, this happens more often than most like to admit. Some swimmers who are insanely fast during their high school years, tend to not improve much or some not at all in college. Of course, there’s always exceptions, but there are a lot of college swimmers who are still trying to beat their high school times.

Masiuk went 52.58 at worlds this year, anyway Diehl looks amazing.

In Paris there might seriously be 7 guys going 51 (Ceccon, kolesnikov, Masiuk, Coetze, 2 of the Americans big 4, Christou) 😲
