Tan, 16, set new personal best times in the girls’ 100 and 200 breaststroke, and she also collected victories in the 100 fly and 200 IM.

In the 100 breast, Tan broke 1:09 for the first time in 1:08.74, improving on her previous best of 1:09.18, set at last summer’s World Juniors, to rank her 17th all-time in the girls’ 15-16 age group. Her previous PB ranked her 25th.

Tan, who represents San Ramon Valley Aquatics, put up a time of 2:28.11 in the 200 breast, which chips two one-hundredths off her previous best time of 2:28.13, set at last summer’s U.S. Speed Junior National Championships, to maintain her spot as the 17th-fastest girl ever in the 15-16 age group.

Tan also won the 200 IM in a season-best of 2:17.28, just over two seconds shy of her best time (2:15.20) to rank her 4th in the 15-16 age group this season. She also clocked 1:01.92 in the 100 fly, good for 8th in the age group this season, narrowly missing her lifetime best of 1:01.86.

On the boys’ side, top-ranked recruit and multi-time NAG record holder Luka Mijatovic was in action, nearing his PB in one of his best events, the 1500 free, while hitting a new lifetime best in the 200 breast.

In the 1500 free, Mijatovic logged a time of 15:17.02, the third-fastest swim of his career and just over a second shy of the 15:15.95 personal best he set at the 2024 Junior Pan Pacific Championships, which ranks him #7 all-time in the 15-16 age group. He now ranks 1st in the 15-16 age group and 4th overall in the country so far this season.

Over the last two years, Mijatovic has gradually shifted to more of a mid-distance focus, especially in long course, as evidenced by the fact that this was only his second LCM 1500 since the summer of 2024. He broke through and qualified for the U.S. World Championship team last summer in the 400 free, and nearly earned a berth on the 800 free relay after becoming the fastest 18 & under American ever in the 200 free at U.S. Nationals.

Racing the long course 200 breast for the first time in two years, Mijatovic took down his lifetime best of 2:30.36 in 2:27.89 to rank 25th in the 15-16 age group this season.

The Pleasanton Seahawks product also swam the 50 free (24.56), 100 back (1:00.54) and 100 fly (56.33). His personal bests in those events stand at 23.98, 59.15 and 54.60, respectively.

This was his first long course meet of the 2026 calendar year, but not his first of the season, having competed at the U.S. Open in December (where he didn’t swim any of the same events).

Ayden Tan, Mikayla Tan‘s younger brother, had some noteworthy performances despite failing to register any personal bests.

The 13-year-old clocked 59.87 in the 100 fly, just shy of his 59.71 best time to rank 4th this season in the boys’ 13-14 age group, while he moved to 5th in the 100 back in 1:01.72, narrowly missing his lifetime best of 1:01.31.

He also went 2:13.18 in the 200 IM, less than four-tenths off his best time (2:12.80) to rank 7th this season in the 13-14 age group, and he also went 25.61 in the 50 free and 55.65 in the 100 free, with his best times standing at 24.95 and 54.91, respectively.

OTHER HIGHLIGHTS

• Pleasanton Seahawks’ product Eli Kim, 13, had a standout showing by going seven-for-seven in personal best times, highlighted by his performances in the 400 free and 200 IM. He dropped more than six seconds in the 400 free, clocking 4:17.18 to rank 9th this season in the 13-14 age group and 2nd among 13-year-olds, while in the 200 IM, he dropped three and a half seconds in 2:17.61, ranking him 13th this season in the 13-14 age group and 4th among 13-year-olds.
• Santa Clara Swim Club’s Aya Gillis-Pade clocked 1:04.15 in the 100 back to rank her 2nd in the girls’ 13-14 age group this season, while her 200 back time of 2:18.92 ranks 3rd. Her personal bests stand at 1:03.47 and 2:15.63, respectively.
• Winning the girls’ 100 back over Gillis-Pade was Daniela Linares-Danzos, the 15-year-old Pleasanton Seahawk who clocked 1:03.15 for the victory. Linares-Danzos set a personal best of 1:00.97 at the Westmont Pro Swim in March, which ranks her 2nd in the girls’ 15-16 age group this season.
• John Sita, a 26-year-old Orinda Aquatics member who previously raced for the University of California College Club Team, put up a notable best time of 29.02 in the 50 breast, which ranks him tied for 37th among American men this season.
