Age group sensation and national teamer Luka Mijatovic is in action in central California at the Roseville Sectionals. The Texas commit is in striking range of several 15-16 NAGs to add to his already-impressive collection. Though he did not get any on the first full night of competition, he got tantalizingly close in the 400 IM on the end of a tough double.

Splitting 50.26/56.31/1:03.50/50.07, Mijatovic topped the 400 IM final by ten seconds with a time of 3:40.14. This puts the Pleasanton Seahawks swimmer less than half a second off Maximus Williamson’s 3:39.83 NAG mark from 2022. The time also beats his previous best, which already put him #2 all-time in his age group, of 3:40.96.

This 400 IM effort came after Mijatovic had already won the 200 free. His time yesterday evening in that event was 1:33.27. This marks his second fastest time ever, trailing the 1:32.73 he produced last December at CA/NV December sectionals. Thomas Heilman remains the event’s 15-16 NAG holder at 1:32.46.

The 400 IM/200 free double on the girl’s side was also quite newsworthy. Sacramento Aquatics’ Lauren Lonsdale had a massive breakout swim in both events at 14 years of age. First, she won the 200 free with a time of 1:46.49, annihilating her previous best of 1:48.26 and moving her up to #2 among 13-14 girls this season. After that swim, Lonsdale put up a 4:12.62 in the 400 IM. This catapults Lonsdale to #3 in the country this season among her age group and marks a seven-second drop from two months ago. 

Another 13-14 sensation in Roseville was Ayden Tan. At 13 years of age, Tan beat a final of high schoolers in the 50 back with a 22.94. It was Tan’s first sub-23 effort and sits over a second ahead of the next-fastest 13-year-old backstroker in 2025-2026 (Jett Hatchard – 24.29). Tan competes for San Ramon Valley Aquatics.
