2023 Swammy Awards: Age Group Swimmer Of The Year – 11-12

See all of our 2023 Swammy Awards here.


Editor’s note: because of ongoing challenges with the USA Swimming results database, identifying all of the top candidates for this year’s age group awards in an objective way has been challenging. We’ve done our best to find them, but it’s possible that we missed someone obvious. If that’s the case, please let us know in the comments!

Huge congratulations to the talented Miss Adalyn! She is a force to be reckoned with 100%! We sincerely hope she and her father can sit back and enjoy this great honor. We hope there is less of him yelling during her races, less tears by the warm down pools and more smiles than frowns on deck simply because she added a half second. She is just 12.This reminds us of another superstar who started at Brea many years ago… It’s sad to see so many swim parents not realize how they can potentially destroy a talented kid’s love of the sport. We hope to see Adalyn continue her rise in the most positive way possible.

Lots of girls on the historical list have become absolute super stars. Men’s list more hit or miss. Makes sense
