Mallory Comerford Smashes U.S. Open Record with 52.81 to Win 100 Free


Louisville’s Mallory Comerford popped a blistering 52.81 to set a new U.S. Open Record and National Championships Meet Record. In doing so, she out-touched reigning Olympic champion Simone Manuel, who was also under the former U.S. Open Record in 53.05 for 2nd place.

Comerford took down the former U.S. Open Record of 53.12 set by current world leader Sarah Sjostrom at the 2016 Arena Pro Swim Series in Austin. The former Nationals Meet Record stood at a 53.26 done by Comerford in prelims. Before today, it was a 53.28 set by Abbey Weitzeil at the 2016 U.S. Olympic Trials.


Comerford’s swim was also just .11 shy of the American Record, which was set by Manuel at the Rio Olympics. This is the first time the Americans will ever send 2 women to a major international meet who have lifetime bests below 53 seconds. Comerford is just the 2nd American ever to break the 53 barrier.

Splits Comparison: Women’s 100 Free

Swimmer 1st 50 Split 2nd 50 Split Final Time
Mallory Comerford (2017 Nationals finals)  25.54  27.27  52.81
Mallory Comerford (2017 Nationals prelims) 25.67 27.59 53.26
Sarah Sjostrom (2016 Austin PSS) 25.83 27.29 53.12

Coach Arthur Albiero on Comerford’s Swim:

“We always talk about putting ourselves in the position to ‘shock the world’  and I guess we did that tonight. Tonight was a paradigm shift for our program,” said UofL head coach Arthur Albiero. “What a swim by Mallory and for Kelsi Worrell too. She guaranteed her spot on the relay. We will wait for final selections for Team USA Junior Worlds and Team USA World University Games, but we believe we should have a few more selected.”

Link to race video anyone?:)

It is hard to say what training stage Simone Manuel is at. If she hasn’t expected any competition and hasn’t at least rested for this meet then 53.05 is a very impressive time. I hope that not winning National Championships won’t hurt her pride and she will come to Budapest mentally strong. Losing to Sjostrom or to Campbell or even to Oleksiak won’t be taken that painfully as losing to the compatriot after being by far the fastest ever American sprinter with a big margin.


Remember she lost to Weitzel last summer at trials.


I don’t know if you remember but one year ago at this time Abbey Weitzeil was #1 American sprinter and #1 American hope in sprint. Simone Manuel at that time was a swimmer who averaged at 53mid -53high with only one two years old under 53.5 race (53.24). Her raise to prominence was very strong and kind of unexpected (to me at least). Her record in 100y cemented her status as indisputable leader in sprint. And as sudden her rise was as sudden and completely unexpected she became #2 nationally. Such swings can be damaging.
But again, if 53.05 is not rested and not tapered then she is fine feeling that some resources hasn’t been used yet.




Really hate to see Simone looking so upset & acting like a poor loser. Didn’t even smile or act happy for Mallory having a great swim!!


oh please…


Congratulating the winner is not a requirement to those who got upset. I remember how Sarah Sjostrom left the pool in Kazan when she has beaten Cate Campbell but has lost to her sister. But it is nice when a swimmer who lost the race makes an effort to recognize the winner. I was actually touched when Cate Campbell congratulated sincerely Sarah Sjostrom with her 52.08
But Mallory Comerford has beaten Simone Manuel for the second time in the shirt period of time in the races of prestige. It can get annoying.


Please just Remove the word Hate – because in truth , u dont hate it – u just feel sorry for her attitude . thats all


Comerford looked amazing. Good for her. We needed another great sprinter with Weitzeil not being on her game
