Siroky entered the day with a lifetime best 30.05 that she swam at 2025 US Summer Nationals during a swim off with Emma Weber. With that swim, Siroky punched her ticket to represent the U.S. at the 2025 World Championships.
The now 21 year old celebrated her birthday today. Her time from today would have been 2nd at the 2025 World Championships as Ruta Meilutyte won gold in a 29.55 and was the only sub-30 second swimmer of the meet. Siroky was 17th in the event in a 30.80.
This upcoming summer will be the 2nd summer that the rising Tennessee junior trains throughout. The 2025 World Championships marked her debut representing the U.S. at the international level.
Siroky now sits at #2 in the World so far this season as only Tang Qianting of China has been faster as she swam a 29.44 back in March.

This Lady Vol is nothing short AMAZING. Just a matter of time before she breaks the WR and exceeds her personal best 58 consecutive pull-ups.
Happy Birthday!
Meh. Don’t like her attitude and how she treated Emma last year.
What did she do to Emma?
She had the audacity to tie her in a final and then beat her in a swim off. This person is attempting to troll and is quickly becoming one of the worst commenters on this site.
“UVA Fan” makes it hard to be a UVA fan.
-signed a UVA alum
You must not be aware of her ready room behavior….
I heard she also caused the corona virus
Well she is a bible thumper so wouldn’t put it past her to disobey public health guidelines….
Again, I do not approve of this message nor the use of the moniker “UVA Fan.”
ugh that makes me like what they’re doing in theory, even tho in execution they’re p bad at it
I’m in this same dilemma which is why I had to call it out
On par with some of UVA’s critics. Although admittedly they have declined.
What a great way to spend your birthday! Happy birthday Siroky!!
